Plant secondary metabolites, including phenolics, represent a large quantity of organic material that enters soil and contributes to the formation of soil organic matter (SOM). The process of phenolics forming SOM remains poorly understood. One possible mechanism is oxidation of the phenolic compound catalyzed by redox active metals such as manganese (Mn) and iron (Fe) in soils. In this work, we report how three phenolic compounds react with a redox active environmentally relevant metal, Mn(IV).

For variable charge soils, acidity is a property that is of equal importance as the surface charge. These two properties may affect each other, with the effect of the former on the latter more remarkable than the reverse. In the previous chapters it was shown that pH affects many other properties of the soil by affecting the surface charge. Therefore, soil acidity is more significant than surface charge in some aspects. Owing to a similar reason, the importance of acidity for variable charge soils may exceed that for constant charge soils. Soil acidity generally manifests itself in the form of

Integrated agricultural practices contribute to increasing and restoring the fertility of washed lands, reducing water erosion of soils on the slopes. When cultivating eroded soils, it is necessary to introduce organic and mineral fertilizers into the arable layer, enrich it with nutrients and eliminate the acid reaction. To do this, you need to carry out deep plowing up to 30 cm with the simultaneous introduction of organic matter and mineral fertilizers. If the soil is acidic, then liming is necessary. This will help to create a better soil environment and better absorption of fertilizers.

Abstract:
Because of the very low level of 90Sr in the environmental soil samples and its determination by beta counting may take several weeks, we developed a procedure for ultratrace determination of 90Sr using collision reaction cell-inductively coupled plasma tandem mass spectrometry (CRC-ICP-MS/MS, Agilent 8800). Soil samples were dried at 105 °C and then heated in a furnace at 550 °C to remove any organics present. 500 g of each soil samples were aliquoted into 2000 ml glass beakers. Each Soils samples were soaked in 2 ppm Sr solution carrier to allow determination of chemical yield. The solid to

Abstract:
Because of the adverse effects of elemental mercury and mercury compounds upon human health, the U.S. Department of Energy (DOE) is engaged in an on-going effort to monitor and remediate mercury-contaminated DOE sites. In order to more cost effectively implement those extensive remediation efforts, it is necessary to obtain an improved understanding of the role that mercury and mercury compounds play in the ecosystem. We have conducted pilot scale experiments to study the bioavailability of mercury sulfide in an Armuchee (eastern US) soil. The effects of plants and incubation time on chemical

Abstract:
A new peptide thrombin inhibitor was found in the Streptomyces griseus strain 254 isolated from a soil sample from Tongan, Fujian province, China, the inhibitor being a secondary metabolic product. The production of the inhibitor reached a maximum after 3 days culture of bacteria at 28°C in a rotary shaker. The inhibitor excreted in the culture filtrate was purified by absorption on macroporous resin, followed by ion exchange chromatography on DEAE-52, CM-32 cellulose, affinity chromatography on the immobilized thrombin and high performance liquid chromatography.

Prolonged application may result in P accumulation up to levels that impair plant nutrition, increase P loss, and promote eutrophication in downstream waters. This study aims to shed light on the RW- and BS-P forms in soils and to follow the processes that determine P reactivity, solu

Abstract:
In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purpo

Abstract:
The sol-gel transition of tetra-coordinated spirosilicate via hydrolysis and condensation under acidic and basic conditions is examined to elucidate the effect of catalyst, reaction time and temperature on the properties of obtained gel. The main advantage of this process is the low temperature employed, producing a solid network with a high specific surface area. FTIR spectroscopy and TGA analysis were used to characterize the formation of siloxane bonds (Si-O-Si). It is found that spirosilicate can be hydrolyzed under both acid and base catalyzed conditions.

Abstract:
Atmospheric deposition can alter biological communities through a variety of pathways. Atmospheric nitrogen (N) deposition causes some plant and animal species to increase growth and/or abundance. Other species then can be outcompeted and eliminated from the biological community. Deposition of reactive N (Nr) to watersheds can impact both aquatic and terrestrial ecosystem elements and contribute to eutrophication and acidification effects. Atmospheric sulfur (S) deposition has been the primary driver of soil and surface water acidification of acid-sensitive ecosystems, resulting in adverse eff

Abstract:
The Bingham Canyon Mine, located near Salt Lake City, Utah, is surrounded by more than 6 billion tons of waste rock developed over the open cut mining history from 1903 to present; the surface area of the waste rock is approximately 5000 acres. Waste rock dumps have a thickness of more than 1 200 feet from crest to toe. From 1930 to 2000, selected portions of the waste rock dumps were commercially leached using a ferric-sulfate-based lixiviant to extract copper, whereas other portions have only received meteoric leaching. From 2011 to present, Rio Tinto Kennecott has studied the evolution and
