Abstract:

Solar radiation and the incorporation of compost into soil is a practice for disinfecting soil that could have some other effects on spinach cultivation. The quality of spinach leaves after two types of soil disinfection, non-amended soil (NAS) and compost-amended soil (CAS), was compared in order to find biomarkers of both types of disinfection. These practices did not show significant differences in nutrient composition (N-P-K) compared to the control soil (CS). However, the amount of harmful nutrients such as NO2− was significantly lower in CAS (65.74 mg kg−1 FW) and NAS (49.99 mg kg−1 FW) than in CS (114.39 mg kg−1 FW). In addition, NO3− levels did not exceed the EU-recommended limit (<3500 mg kg−1 FW). Both types of disinfected soils produced higher concentrations of total phenols and more individual flavonoids in spinach leaves than the control. Combined chemometric analysis of the HRAMS data showed different clustering depending on the type of disinfection (NAS and CAS). Fifteen metabolite compounds could be identified, seven of which are beneficial for health and were more abundant in spinach grown in CAS compared to that grown in NAS or CS. Such beneficial metabolites measured with non-target analysis as markers of CAS-grown spinach. However, more studies are necessary in order to determine the differences between the metabolites of spinach grown in NAS or CAS.

Abstract:

Soil is a favorable environment for many microorganisms, pathogenic bacteria, fungal spores, insect eggs due to the presence of nutrients and moisture in it. Soil treatment from pests and pathogens of agricultural crops for disinfection can be carried out by chemical, energy, thermal, biological methods. The most common method is thermal. This is because many pests and pathogens have a protein structure that is easily destroyed when the temperature increases, and the thermal effect can be obtained from various heat carriers. (Research purpose) The research purpose is in developing an energy-efficient method of soil disinfection using infrared radiation. (Materials and methods) The article shows the relation between the spectral thermoradiation characteristics of soil with characteristics of infrared emitters, namely the amount of applied heat, temperature, conductivity, soil moisture, and exposure time, to justify the rational mode of operation for decontamination of the soil. The article presents a mathematical model for this purpose based on known laws that determine the relationship between the necessary parameters. (Results and discussion) Authors offered a plant for soil disinfection with infrared radiation. It was found that the high energy efficiency of the installation is achieved by a high efficiency of infrared burners and infrared radiation affects directly the object of treatment, the soil. The article presents structural-logical and mathematical models of infrared power supply. (Conclusions) Analysis of the heating kinetics equation showed that the maximum permissible speeds for the process of infrared heating of the soil depend on its thermophysical properties, the maximum permissible temperature, the area and the required depth of warming of the soil. It was found that infrared heating and a device for disinfecting the soil in this way will allow energy-efficient, convenient and fast processing.

Abstract:

Replant syndrome (RS) is a global problem characterized by reduced growth, production life, and yields of tree fruit/nut orchards. RS etiology is unclear, but repeated monoculture plantings are thought to develop a pathogenic soil microbiome. This study aimed to evaluate a biological approach that could reduce RS in peach (Prunus persica) orchards by developing a healthy soil bacteriome. Soil disinfection via autoclave followed by cover cropping and cover crop incorporation was found to distinctly alter the peach soil bacteriome but did not affect the RS etiology of RS-susceptible ‘Lovell’ peach seedlings. In contrast, non-autoclaved soil followed by cover cropping and incorporation altered the soil bacteriome to a lesser degree than autoclaving but induced significant peach growth. Non-autoclaved and autoclaved soil bacteriomes were compared to highlight bacterial taxa promoted by soil disinfection prior to growing peaches. Differential abundance shows a loss of potentially beneficial bacteria due to soil disinfection. The treatment with the highest peach biomass was non-autoclaved soil with a cover crop history of alfalfa, corn, and tomato. Beneficial bacterial species that were cultivated exclusively in the peach rhizosphere of non-autoclaved soils with a cover crop history were Paenibacillus castaneae and Bellilinea caldifistulae. In summary, the non-autoclaved soils show continuous enhancement of beneficial bacteria at each cropping phase, culminating in an enriched rhizosphere which may help alleviate RS in peaches.

The soil is a favorable environment for many microorganisms, pathogenic bacteria, fungal spores, insect eggs due to the presence of nutrients and moisture in it. Soil treatment from pests and pathogens of agricultural crops for the purpose of disinfection can be carried out by chemical, energy, thermal and biological methods. The most common method is thermal. The article proposes to use infrared heating as an alternative energy source. (Research purpose) The research purpose is developing energy-resource- saving installations for disinfection of soil and substrate. (Materials and methods) The article presents three devices and their capabilities for disinfection of soil and substrate with infrared radiation. (Results and discussion) One of the options for progressive scientific and technical developments is the development of software management of soil and substrate disinfection for the implementation of energy-saving electrical technologies, which regulates parameters depending on the set values: heating time, height of the frame with IR burners above the ground, humidity, porosity, soil temperature, ambient temperature and power of infrared burners. (Conclusions) During the analysis of the state and prospects for the tillage before planting, the need for the development of scientifically based devices for disinfection of soil and substrate was justified. The proposed use of software control of soil and substrate disinfection will allow setting and maintaining the required level of treatment depending on the technological process, type of soil, open or closed ground. The use of an automatic disinfection control system will make it possible to achieve optimal processing parameters and increase productive indicators.

Abstract:

Manure as an organic fertilizer in practice of agriculture is allowed to use only if it does not contain pathogenic microorganisms. Upon detection in manure and chicken droppings of pathogens of infectious diseases is carried out their disinfection. Choosing method of disinfection is carried out at the direction of veterinary service taking into account danger of arising of epizootic situation, type of pathogen of disease, presence and type of chemical reagents and technical means. For disinfection of animal by-products by chemical method we use a large number of disinfecting agents potentially hazardous for the environment which is associated with the content in their composition of xenobiotics, in particular aldehydes, chlorine, phenols, etc. The paper presents results of biotesting of soils polluted by disinfecting agents used for disinfection animal by-products, in particular, bioethanol, Novochlor-Extra (contain such active substances how inorganic chlorine compounds and alkali) and Dezaktin (organic chlorine compounds, anion SAS and sodium tripolyphosphate). The assessment was carried out under laboratory conditions through biotesting with the use of spring barley (Hordeum vulgare L.). It is established, that after five-day cultivation of barley seeds in soils containing 1.0, 10.0 and 100.0 mg/kg of such agents as bioethanol, Novochlor-Extra and Dezaktin there was gradual reduction of mass of stem to 10.2% compared to a control. When the content in soils was 1.0, 10.0 and 100.0 mg/kg of investigated disinfectants gradual reduction of length of stem of barley by an average of 12.2% was observed. At pollution of soil investigated agents in the number of 1.0, 10.0 and 100.0 mg/kg we observed the small increase of length of longest of root by an average of 7.8%, which indicates to stimulating influence on the growth of root system and absence of phytotoxicity. When the content of disinfectants bioethanol and Novochlor-Extra in soils was in a quantity of 1000 mg/kg, there was reduction of mass, length of stem and longest root of an average of 19.1, 30.5 and 16.8%, respectively. At pollution of soil at the level of 1000 mg/kg agent of Dezactin we observed reduction of mass of stem to 61.8%, its length on 72.0% and length of longest of root to 67.4% that demonstrated to phytotoxic influence. At the hit of disinfectants with disinfected animal by-products in soils in a quantity of ≥1000 mg/kg it is possible to predict negative impact on morphometric indicators of plant what probably will lead to worsen of their development. The method of determination of pollution of soils by delay growth of root of plants is informative express method for ecological assessment of content in them the disinfectants used for disinfection of animal by-products.

Abstract:

Concerns about the widespread use of pesticides have been growing due to the adverse effects of chemicals on the environment and human health. It has prompted worldwide research into the development of a replacement to chemical disinfection of soil. The efficiency of steam sterilization, an alternative to chemical methods, has improved as technology has advanced, and the Agricultural Research and Extension Service in Korea recommends the use of steam sterilization. However, few studies have been conducted on the effects and operating conditions of high-temperature steam disinfection. In this study, we present the optimum operating conditions of a high-steam disinfector, to maximize the cost-effectiveness and removal efficiency of total nematodes and total bacteria in soil using the Box−Behnken design. The experimental data were fitted to a second-order polynomial equation using multiple regression analysis, with coefficients of determination (R2) for each model of 0.9279, 0.9678, and 0.9979. The optimum conditions were found to be a steam temperature of 150.56 °C, running speed of 1.69 m/min, and spray depth of 15.0 cm, with a corresponding desirability value of 0.8367. In the model, these conditions cause the prediction of the following responses: nematode removal efficiency of 93.99%, bacteria removal efficiency of 97.49%, and oil consumption of 70.49 mL/m2. At the optimum conditions for the steam disinfector, the removal efficiencies of nematodes and bacteria were maximized, and the oil consumption was minimized. The results of our study can be used as basic data for efficient soil disinfection using high-temperature steam.

Abstract:

With the increasing level in the intensification of agricultural production in China, continuous cropping obstacles have become a problem that needs to be solved. The use of vertical rotary tillage technology and soil disinfection technology is an effective solution. In this paper, a vertical rotary soil-tilling variable disinfection combine was developed and an on-board control system with STM32 as the control core was designed to realize the real-time acquisition of powder monopoly torque information and the variable application of soil disinfection chemicals. Based on the obtained experimental soil parameters, a discrete element soil particle model was established, and orthogonal experiments were conducted to analyze the single-blade roller tillage process, and the optimal operating parameters were finally selected as 500 mm powder monopoly depth, 320 r/min knife roller speed, and 0.26 m/s forward speed, respectively. The field experiment found that the average tillage depth of the implement was 489 mm, the stability coefficient of tillage depth was 94.50%, the uniformity coefficient of soil disinfection was 85.57%, and the applied amount and the speed ratio coefficient of the given flow were linearly related, respectively. This research provides a technical reference for the deep tillage and soil disinfection of the powder monopoly.

Abstract:

Growing greens is always accompanied by the development of pests and diseases, the fight against which is an integral part of obtaining a high and high-quality harvest. Heat treatment is one of the best ways to combat plant diseases and pests. Allows you to quickly create the necessary sterile conditions without the use of chemicals. For heat treatment, a device is being developed for disinfecting soil and substrate in a thin layer using IR radiation on a conveyor belt. The prepared soil mixture from the supply hopper falls onto the conveyor belt in a thin layer. An IR emitter with adjustable power within the range of 4...10 kW is installed above the conveyor belt. The movement of the conveyor belt should ensure that the surface of the soil mixture is heated to 100 °C. This is controlled by a temperature sensor, which sends a signal via a programmable relay to the conveyor motor and regulates its movement. The disinfection process makes it possible to achieve high energy efficiency through software regulation, taking into account optimal modes and control of the processing temperature.

Abstract:

Microbes survive for an extended period of time on fomites. With new strains of pathogens constantly emerging, it is important to understand their survival and spread and to evaluate the efficiency of new disinfection methods. The purpose of this study was to determine the occurrence of pathogens on fomites, and evaluate different disinfection methods (household bleach and steam vapor). Fomites were sampled in a variety of environments for the presence of pathogens including methicillin intermediate- and resistant- Staphylococcus aureus, Clostridium difficile, Penecillium brevi-compactum, Alternaria alternata and novel H1N1 influenza A. Samples were assayed using both cultural and genetic techniques to determine the microbial occurrence. In disinfection studies, samples were collected before and after disinfectant application. Steam vapor was effective at reducing microbial occurrence by>90% with a minimal contact time of 10-20 seconds on hospital fomites. The material and shape of the surface had an effect on the reduction rate, due to access of the disinfecting agent. In addition, low levels of initial contamination limited the reduction rate. Many surfaces had a starting contamination level of less than 3 log10 and after disinfection the contamination levels, in 69% of the samples, were at or near the limit of detection. This suggests a higher reduction is feasible. Household bleach reduced the presence of mold spores and mycelium by >99% on gypsum-wall board. Reduction rates were influenced by the growth stage of mold, with the mycelium requiring additional disinfectant application to achieve the 99% reduction rate. Novel H1N1 influenza A was not recovered on any surfaces in day care facilities and elementary schools. This is consistent with previous studies looking at H1N1 influenza occurrence in similar environments, though it is different from H3N2 influenza A studies. Survival differences among varying influenza strains are expected to have an impact on pathogen spread and human health risks. Differences can be quantitatively evaluated and used to develop more advanced risk assessment models. Steam vapor and household bleach are effective at reducing risks of pathogens in the environment and are critical interventions in an overall strategy to minimize exposure and prevent disease.

Soil-borne diseases is a problem farming must face. To maintain agricultural products under the premise of quality, agricultural facilities start being applied. In cultivation of agricultural facilities to guard against climate change, natural disasters and pests, and effectively manage the environment for crop growth through automation. Modern agriculture mostly uses pesticides and other chemical additives to resist and suppress a variety of pests and diseases. In addition to the efficacy of being easily absorbed by soil particles, if it fail to be managed and used properly, it would not only cause permanent damage to the soil but also indirectly threaten other creatures such as bees living environment. The deduction of bees has an impact on the opportunities for bees to pollinate plants. Therefore, a vicious cycle poses a threat to biology and environment. Actually we may attribute the disasters to man-made factors. The target of this research is to convert a conversational microwave oven into a movable one and to record the speed and wattage microwave machine at the time of microwave soil sterilization that measured by the heat treatment process. After comparing soil depth with temperature through the data, soil insects harmful bacteria with rising temperature of the elimination of levels. We expect to apply microwave technology in the prevention of job processing of agricultural land management. This study of literature case in 1946, Raytheon Company (Raytheon) radar engineer Percy Spencer, the test generating microwaves 'magnetron', the unexpected discovery pocket candy dissolved, presumably wave having a heating function, leading to the invention of the microwave oven. In this study, case studies, examples of microwave heating of the soil, using the energy directly into the technology. Of "medium" for disinfection, for the effects of combustion or decomposition of the constitution concerns the impact, which save space and time and energy purposes, sterile and achieve consistent operation of the production line. In this study, experimental analysis of the scientific research methods of experiment. Starting in 1920, created by the mathematician Ronald Fisher. As an experimental method which operates under the control of the academic research environment variables to test the hypothesis. As deemed appropriateness, the use of methods necessary for the performance of this study. Confirmed by this study that the conclusions are as follows: Conclusions first, In order to reduce the harm effects of pesticides on soil environment, the present study the experiment proved that due to the soil via microwave for 2 to 3 minutes, can lower soil depths of 10 cm reached a temperature of Celsius 50 to 55 degrees, by the present study demonstrated that temperature can kill In addition to pathogens and nematode populations. Use the heat treatments characteristics for reaching and solving the impact of pet disaster. Conclusion second, the wattage of the microwave heat treatment temperature level of influence, the experiment proved that the present study, increasing the relative humidity of the soil, can reach temperature microwave heat treatment to enhance the soil. Conclusion third, after the experiment that, to maintain the soil temperature time up sterilization effect, can be used with spray and soil vapor after forming of silicon production industry microwave.

Abstract:

Indiana University-Purdue University Indianapolis (IUPUI)
Organic-rich substrates such as soil provide an excellent carbon source for bacteria. However, hydrocarbons such as those found in various ignitable liquids can also serve as a source of carbon to support bacterial growth. This is problematic for fire debris analysis as samples may be stored at room temperature for extended periods before they are analyzed due to case backlog. As a result, selective loss of key components due to bacterial metabolism can make identifying and classifying ignitable liquid residues by their chemical composition and boiling point range very difficult. The ultimate goal of this project is to preserve ignitable liquid residues against microbial degradation as efficiently and quickly as possible. Field and laboratory studies were conducted to monitor microbial degradation of gasoline and other ignitable liquids in soil samples. In addition to monitoring degradation in potting soil, as a worst case scenario, the effect of soil type and season were also studied. The effect of microbial action was also compared to the effect of weathering by evaporation (under nitrogen in the laboratory and by the passive headspace analysis of the glass fragments from the incendiary devices in the field studies). All studies showed that microbial degradation resulted in the significant loss of n-alkanes and lesser substituted alkylbenzenes predominantly and quickly, while more highly substituted alkanes and aromatics were not significantly affected. Additionally, the residential soil during the fall season showed the most significant loss of these compounds over the course of 30 days. To combat this problem, a chemical solution is to be immediately applied to the samples as they are collected. Various household and commercial products were tested for their efficacy at low concentrations to eliminate all living bacteria in the soil. Triclosan (2% (w/v) in NaOH) proved to be the most effective at preserving ignitable liquid residues for at least 30 days.

Titanium dioxide (TiO2) is extensively used as a photocatalyst due to the strong oxidizing power of its holes, high photostability and redox selectivity. The anatase phase TiO2, in particular, has been greatly studied due to its high photocatalytic activity for the decomposition of various organic pollutants in the environment and the disinfection of microorganisms. In this work, nanometer-sized TiO2 was synthesized using Ti[O(C4H9)]4 as a precursor of TiO2 and acetic acid (CH3COOH) as a peptizer. The initial sol was hydrothermally treated at 200 ºC for 5 h, followed by calcination for 1 h at three different temperatures (600、700 and 800 ºC). The as-prepared TiO2 samples were coated on to glass substrates and evaluated for their bactericidal ability against Staphylococcus aureus. The commercial Degussa P-25 was included in the study for comparison. The death rate of S. aureus was found to follow the first order kinetics: log (Nt/N0) = -kt (Nt: the number of viable cells at time t, N0: the initial cell counts, k: rate constant), and the rate constant k decreased with increasing calcination temperature. The results show strong correlation between the hydrothermal treatment conditions and the properties of the resulting TiO2 particles, such as structure evolution and particle size of the TiO2 samples and their germicidal activity. High calcination temperature resulted in aggregation, as well as phase transformation from anatase to rutile. By drying the initial sol prior to the calcination step, the hydroxyl groups on the TiO2 surface were greatly reduced, resulting in less aggregation and smaller particle size of the resultant TiO2. The bactericidal activity was also improved. Therefore, it is concluded that the anatase phase and surface area are two dominate factors that control the disinfection activity of TiO2 under the given experimental conditions.

Abstract:

AbstractHydroponics is a method to grow crops without soil, and as such, these systems are added to aquaculture components to create aquaponics systems. Thus, together with the recirculating aquaculture system (RAS), hydroponic production forms a key part of the aqua-agricultural system of aquaponics. Many different existing hydroponic technologies can be applied when designing aquaponics systems. This depends on the environmental and financial circumstances, the type of crop that is cultivated and the available space. This chapter provides an overview of different hydroponic types, including substrates, nutrients and nutrient solutions, and disinfection methods of the recirculating nutrient solutions.

Abstract:

The demand for the development of eco-friendly, sustainable, and adaptable technologies for the disinfection of the environmental contaminants is increasing nowadays. Nano-bioremediation is one such technique that has made possible the use of biosynthetic nanoparticles for soil pollution remediation. It is an effective, efficient, and feasible method for revitalizing soil potential and rendering it pollution free. Pollutants present in soil are a great threat to soil biota, environment, and in fact human health. Nanomaterials exhibit the unique chemical and physical properties because of which they have always received attention in the growing era of bioremediation. Use of nanotechnology for bioremediation is one such technology as it focuses mainly on the interaction between the contaminants, the microorganisms, and the nanomaterials being used for both the positive (i.e., stimulating) and negative or toxic environmental effects. Thus, this chapter focuses on the need to recover the polluted soil and application of nano-remediation technology for restoring soil's cultivation capacity.

Full text

Abstract:

Humic substances are the main constituents of natural organic matter, found in both aquatic and terrestrial environments. Humic substances are a complex, dispersed, and heterogeneous mixture of various organic compounds synthesized from organic matter residues, decomposed by microorganisms. Most scientists indicate that humic substances are as a supramolecular association of small heterogeneous molecules stabilized by weak intermolecular bonds. When these substances are presented in water intended for drinking or industrial use, it can have a significant impact on the treatability of this water and on the success of chemical disinfection processes, due to possible formation of organic compounds harmful to human health. Moreover, the humic substances can be used of several ways such as fertilizer to help in the development of plants, to improve soil erosion and to removal of organic compounds and metals from soils and waters. In addition, humic substances suggest an important role in mitigating areas degraded by the phytoremediation technique. The purpose of chapter is to provide an overview of humic substances and to discuss their concepts, chemical characteristics, ecological effects and technological applications for soils and aquatic systems.

Abstract:

Bacterial soft rots of banana and plantains involve two different diseases caused by related but distinct pathogens: rhizome soft rot or head rot by Pectobacterium carotovorum. subsp. carotovorum and pseudostem wet rot and rhizome rot - in some parts of the world called rhizome necrosis and corm rot-, caused by Dickeya paradisiaca. Although considered minor diseases, they cause losses of individual plants, yield reduction and raise the cost of production. Bacterial soft rots are found in wet humid soils with poor drainage, and high pH, during prolonged wet periods. Affected plants show poor shoot emergence, dwarfing, scorching of the lower leaves, and wilting and rot of the youngest emerging leaves. Rhizome infection causes a pseudostem wet rot progressing upward from infected rhizome and from petioles downward and a spongy necrotic collar at the union of rhizome with the pseudostem. Bacterial soft rot pathogens can be diagnosed by microbiological and molecular techniques. Disease management relies on use of healthy planting material, plant to plant tools disinfection and improving soil drainage and cropping practices.

Abstract:

Improvements in nuclear magnetic resonance (NMR) instrumentation, magnetic field strength, pulse sequences, and computer technology and software have increased the range of applications and specific elements available for study by NMR. The five chapters in this Part clearly indicate the benefits of these advances, especially regarding studies of aquatic, environmental significance. Each of the studies focuses on environmentally significant issues. For example, chlorination is widely used to disinfect drinking waters, a method that can produce undesirable disinfection by-products. This was first recognized in 1974 with the discovery of trihalomethanes in most finished drinking waters where hypochlorite was used for disinfection. Chapter 7 examines the chlorination of alanine and relates it to the chlorination reactions of acetaldehyde and ammonia, a topic of importance with respect to drinking water disinfection. Aluminum is also widely used in drinking water treatment, and understanding its hydrolysis chemistry and complexation behavior is of great importance to aquatic chemistry. In addition, the aquatic chemistry of aluminum is important because acid rain can release soluble aluminum ions from clay into soil water, possibly damaging terrestrial plant life. Aluminum may eventually reach and accumulate in hydrological systems where it can be toxic to aquatic life. Chapters 8 and 9 focus on 27Al NMR in defining aqueous aluminum speciation in a mildly acidic solution or in the presence of complexing organic compounds. Furthermore, aluminum is of environmental and geochemical significance since it is an integral component of clays, another ubiquitous constituent of natural waters (surface and ground). Interaction between clays, cations, and internal water molecules can be significant in understanding the fate and transport of chemicals through the environment. Since colloidal suspensions of clay materials frequently represent challenges to water and wastewater treatment, understanding of physical and chemical processes are of tantamount importance to the environmental scientist and engineer. Chapter 10 explores cation behavior in clay matrices by using “uncommon” nuclei such as 7Li, 23Na, and 133Cs as probes. This is unique in that many NMR studies of complexation in clay have focused primarily upon the nuclei 27A1 and 29Si.

Full text

Abstract:

Humic and fulvic acids, which can be extracted from soils, are abundant in surface water because of their high discharges from runoff during torrential rainfall, storm events, and summer monsoon. Both humic and fulvic acids adversely affect water supply as they produce disinfection by-products (DBPs) during chlorination and serve as the sorbent for the binding of hydrophobic organic contaminants. In the present study, we conducted chlorination and phenanthrene sorption for humic and fulvic acids that were extracted from nine soil samples. We also analyzed and compared their characteristics by using elemental 13C NMR analysis, spectroscopy analysis, and size exclusion chromatography. Our results showed that the changes in their structural characteristic, their DBP formation, and phenanthrene sorption behavior differed critically between humic and fulvic acids. For chlorinated humic acids, high SUVA, low molecular weight, low N/C, and low O groups of aromatic C were associated with high trihalomethane (THM) formation. In comparison, low O groups of aliphatic C in fulvic acids were associated with both oxidation and incorporation in terms of THM formation. Humic acids exhibited higher sorption ability than fulvic acids due to their higher MWw, SUVA, and %THLF. These findings provide key information for monitoring water quality in rivers and lakes.

Abstract:

Experimental selection of disinfectants for industrial disinfection of soil, ground, bottom sediments, and sewage sludge contaminated with helminth eggs is carried out in several stages. Laboratory tests have shown that only 2 products have an optimal disinfection effect out of 20 disinfectants of different chemical nature tested on soil samples contaminated with swine roundworm eggs. The soil disinfection modes established in laboratory conditions for selected disinfectants are not effective in disinfecting large volumes of soil. It is proposed that scaled tests of selected disinfectants be performed on soil samples contaminated with helminth eggs before industrial soil disinfection to develop disinfection technology for large volumes of soil. Using a device for scaled disinfectant testing that simulates the structure, density, physical, biological and chemical properties and characteristics of multi-layer soil in various ecosystems, technological modes are established for the disinfection of industrial volumes of soil. The established concentrating and timing parameters of industrial soil disinfection provide high-quality disinfection in various ecosystems and completely eliminate environmental pollution with ineffective disinfectants or ineffective concentrations of standard disinfectant solutions against helminth eggs.

Abstract:

Soil, bottom sediments, and sewage sludge are the main sources of infection of humans and animals with helminth eggs, and protozoan cysts and oocysts. For the disinfection of environmental objects, chemical disinfectants are successfully used. To identify the most effective disinfection means for soil and environmental objects, laboratory studies of the ovicidal activity of disinfectants are carried out on soil samples. Currently, laboratory practice has no standard methods available for determining the ovicidal efficacy of disinfectants in the soil. A device is offered for the experimental selection of disinfectants for disinfecting soil, geologic material, sewage sludge or bottom sediments contaminated with helminth eggs, and protozoan cysts and oocysts. The laboratory device is a three-segment steel column in the form of a cylinder with supports provided at the base, and a cover with a foam outlet and a filler neck located on the upper part, and a storage tank for collecting the spent disinfectant solution located in the lower part. The cylinder is filled with soil segment by segment, and microcontainers with bioagent are placed at the bottom of each segment. The soil is poured with a disinfectant; and the microcontainers are removed from the soil after various exposure periods to determine the ovicidal activity of the disinfectant.

Abstract:

This study aimed to identification of an ecological alternative for the chemical disinfection of soil in the greenhouses from Romania. Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops in the world. The carbohydrate, vitamins, salts of important mineral elements and organic acids content of tomato fruits is very important. Tomato crops are very sensitive to climatic vagaries, so fluctuation in climatic parameters at any phase of growth can affect the yield and the fruit quality. Grafting on Solanaceae is a method which has improved and spread quickly during the past years, a similar approach to crop rotation, a practice meant to increase productivity, resistance or tolerance to biotic and abiotic stress factors and at increasing fruit quality. The research was conducted in a glass greenhouse of the Horting Institute, Bucharest, Romania. The biological material used was a Romanian tomato hybrid (Siriana F1), a Dutch tomato hybrid (Abellus F1) and four rootstocks, a Dutch tomato hybrid (Emperador F1) and three Romanian tomato cultivars (L542, L543 and L544) obtained from the Research and Development Station for Vegetable Growing, Buzău, Romania. The rootstocks have had resistance to biotic stress factors (soil diseases and pests) and the chemical disinfection of soil has was eliminated. The result of this research are presented in this paper.

Abstract:

The results of many years of research revealed that in the conditions of the Udmurt Republic, in the soil on the territory of the ground runs of livestock enterprises, eggs of nematodes of the suborders Trichocephalata, Strongylata and Rhabdidata, and Eimeria oocysts were found. At the same time, Eimeria oocysts were stationary dominant in terms of quantity per 1 gram of soil (on average, from 204.4±13.9 to 267.4±15.7 pieces). Of the eggs of helminths, exogenous stages of representatives of the suborder Strongylata spp. were most often found, on average 166.1±9.2. In order to assess the effectiveness of soil disinfection on the ground runs, a hot solution of sodium hydroxide (caustic soda) was studied at a 5% concentration at a rate of 1 L/m2 with a 6-hour exposure and a Ligrocid at a 0.25% concentration at a rate of 0.25 L/m2 with 20-min. exposure. The results of our studies showed that when using Ligrocide, the intense-effectiveness of treatment against exogenous stages of helminths from the suborders Strongylata and Rhabdidata was 100%. However, despite its high efficiency, a single treatment does not completely destroy whipworm eggs and Eimeria oocysts. The degree of soil contamination with these parasites remains at the level of 5.6–16.8%. It was found that the soil disinfection on the ground runs of livestock enterprises with 5% sodium hydroxide was ineffective both against protozoan oocysts (intense-effectiveness, 65.6%) and nematode eggs (intense-effectiveness from 20 to 77.8%).
