Abstract:

Shade trees undergo periodic dehydration because the rate of absorption of soil water lags behind the rate of transpirational water loss from tree crowns. The rate of absorption of water from wet, warm, and well-aerated soil is controlled largely by the rate of transpiration. However, absorption of water often is impeded by low soil moisture content, a small or slow-growing root system, poor soil aeration, low soil temperature, a high concentration of the soil solution, or combinations of these. As the soil dries down from field capacity, the rate of absorption of water is reduced because of i

A nutritional survey was conducted to study the influence of variety and rootstock on interactionamong K+, Ca++, Mg++and Na+ ions in grape during 2012-14. Soil cation contents did not correlatewith their respective contents in petioles indicating a strong antagonism among them. Quadraticrelationship of soil cations with the absorption (ratio of petiole content to soil content) of otherions revealed that the antagonism among cations was observed in case of soil K+ with Ca++ andNa+ absorption on 110R and Dog Ridge rootstocks, soil Ca+ with K+ and Mg++ and Na+ in Sonakavariety and Na+ in own root

Abstract The aim of the present work is to investigate the radiation absorption capacity of different soil samples in Turkey. For this purpose, we used a γ ray transmission geometry to measure the mass attenuation coefficients of eight soil samples collected between Bingöl city and Solhan district, Turkey at different γ-ray energies in the range of 13.94–88.04 keV. The radioactive sources utilized in the experiment were 241Am, 109Cd and 133Ba.

A two-year study was conducted to determine how soil texture affects calcium (Ca) absorption and partitioning in potted ‘Hass’ avocado trees. Trees were planted in 200 L pots in one of four soil types: clay (C), clay loam (CL), sandy loam (SL) or sand (S). Prior to planting, Ca content in each soil was in the normal range of availability, although the Ca concentration was highest in C soil. After two years of tree development, dry weights of shoots and roots were significantly higher in the SL and S soils than in C soil. Trees in the C soil had higher wood dry weight than trees in SL or S soil

Abstract:

The hydrological and mechanical behavior of soil is determined by the moisture content, soil water (matric) potential, fines content, and plasticity. However, these parameters are often difficult or impractical to determine in the field. Remote characterization of soil parameters is a non-destructive data collection process well suited to large or otherwise inaccessible areas. A ground-based, field-deployable remote sensor, called the soil observation laser absorption spectrometer (SOLAS), was developed to collect measurements from the surface of bare soils and to assess the in-situ condition

The experimental plots were established in natural forest stands of mature and overmature ages in different edatopes of forest growth – A2, B2, B3, C2, C3, D2 (according to Alekseev-Pogrebnyak's edaphic net). Forest stands formed mainly by Pinus sylvestris L. and / or Quercus robur L. The investigated natural forest stands are characterized by high forest plant effect, which can be explained by the favorable values of the soil’s physicochemical properties (pHH2O, pHKCl, amount of absorbed bases, absorption capacity, degree of saturation of bases).The analysis of physicochemical properties of s

Abstract:

The determination of a transport mechanism for genistin (genistein-7-O-glucoside) across the tonoplast was performed on vacuoles from a cell culture of Trifolium pratense L. Genistin levels were examined in vacuoles as well as in an assay medium by HPLC (high-performance liquid chromatography) after treatment with various substances. MgATP increased the uptake of added genistin by 25%, but the nucleotide-free samples also contained this glycoside. Applying bafilomycin A1, an H<sup>+</sup>-ATPase inhibitor, indistinctly inhibited genistin absorption. However, vacuolar absorption of

The problem of soil parameters modeling and input data preparation are considered in the article. The use of Soil and Water Assessment Tool was analyzed. The question of the soil water content and basic soil agronomic characteristics was considered. The SWAT project was created for the period of 2014-2017 years and could be prolonged. A soil map and cartographic information were digitized for the analysis of soil characteristics. An assessment of soils moisture absorption in different key areas was made in the course of the research.

Tithonia diversifolia is arobust shrub that has high ecological plasticity and adaptability, high capacity of nutrient absorption and high nutrient contents. These characteristics make Tithonia diversifolia be considered as a multi-purpose plant, such as for animal feed, soil decontamination and soil restorer. Likewise, it is a plant with high ecological plasticity and adaptability. The study of the nutrient absorption and the fertilization represent an important advance in the development of productive systems focused on maximizing forage productivity, which guarantees the soil sustainability

Abstract:

The paper considers the information and energy assessment of soil fertility. It is shown that soil cultivation is accompanied by an increase in soil humus content, absorption capacity, content of biophilic elements, accumulation of energy in the soil, optimization of information relationships in the soil. Thus, the energy content in poorly and well cultivated sod-podzolic soils was 351.7 and 510.7 million kcal/ha, respectively. When cultivating soils, the content of mobile forms of biophilic elements in them increased, the relationship between soil properties and crop yield became more stable.

Oil spills have been one of the greatest environmental problems worldwide. The contamination of soils due to oil spills generates an oil migration down the soil until reaching groundwater. The research focused on remediation of oil-contaminated soils by Ecuadorian natural and acid-surfactant modified zeolites of the Cayo Formation. The natural and modified zeolites were characterized by wavelength dispersive X-ray fluorescence, X-ray powder diffraction, environmental scanning electron microscopy, attenuated total reflectance Fourier transform infrared spectroscopy, and solid-state magic-angle

Abstract:

Fires can alter the hydraulic properties of burned soils through the consumption of organic matter on the ground surface. This study examined the effects of rainfall on the presence of soil pore clogging with varying ash layer thickness using laboratory rainfall simulator experiments. The image analysis with resin impregnation showed that rainfall impact caused plugging of soil pores at 22.2% with soil particles and 14.3% with ash particles on near surface soils (0–5 mm below). High rainfall intensities enhanced soil pore clogging by ash particles, particularly at shallow soil depths (0–10 mm)
