Organic Molecular Markers in a Fluvisol Amended with Organic Ameliorants

Proceedings of the Bulgarian Academy of Sciences, 2022
Three types of organic ameliorants, sheep manure, sewage sludge from a waste water treatment plant and a plant compost were added to an Alluvialmeadow soil (Fluvisol). There was evidence for well-preserved biomarker signals and higher values of the carbon preference index (CPI) in the sludge and manure-treated soils, while lower values, typical of ...

Soil organic carbon is affected by organic amendments, conservation tillage, and cover cropping in organic farming systems: A meta-analysis

, 2021
Meta-analysis is often used to compare how soil health differs between organic and conventional farming systems. However, the burgeoning primary literature on organic farming now allows direct evaluation of the best management practices (BMPs) within ...

Carbon sequestration under different organic amendments in saline-alkaline soils

, 2021
Organic amendments are a recyclable resource and can improve soil quality and carbon (C) sequestration, however, the difference in their effects on soil aggregate formation and C sequestration in saline-alkaline soils are less studied.

Organic amendments affect soil organic carbon sequestration and fractions in fields with long-term contrasting nitrogen applications

Agriculture, Ecosystems & Environment, 2021
Organic amendments are widely used to both manage soil organic C (SOC) and improve soil fertility in agro-ecosystems. However, crop production and the mechanisms of SOC sequestration following organic amendment may be affected by long-term differential N

Terbuthylazine persistence in an organic amended soil

Journal of Environmental Science and Health, Part B, 2008
The aim of this work was to study the effect of the application of a solid waste from olive oil production (alperujo) on the movement and persistence of the herbicide terbuthylazine (N2-tert-butyl-6-chloro-N4-ethyl-1,3,5-triazine-2,4-diamine). An experimental olive grove was divided in two plots: (i) Plot without organic amendment (blank) and (ii) Plot

Interactions of diuron with dissolved organic matter from organic amendments

Science of The Total Environment, 2009
Diuron is frequently detected in some drinking water reservoirs under the Burgundy vineyards, where organic amendments are applied. The environmental effect of these amendments on pesticide transport is ambiguous: on the one hand it could enhance their retention by increasing soil organic carbon content; on the other hand, dissolved organic matter (DOM)

Influence of Organic Amendments on the Degradation of Endosulfan

Bulletin of Environmental Contamination and Toxicology, 2012
A laboratory experiment was conducted to study the effect of soil amendments with four different sources of organic matter on the dissipation rate of endosulfan. Farm yard manure (FYM), vermi compost, leaf compost and charcoal, dried, ground (

Influence of organic amendments on the mobilization of molybdenum in soils

Bulletin of Environmental Contamination and Toxicology, 1990
Recent attention has been focused on toxic levels of selenium (Se), arsenic, chromium, mercury, boron and molybdenum (Mo) accumulating in saline agricultural evaporation pond waters. Although this is an effective disposal practice for agricultural drainage water, the ponds attract wildlife and waterfowl which may create adverse environmental risks ...

Effect of Organic Amendments on Degradation of Atrazine

Bulletin of Environmental Contamination and Toxicology, 2009
Pesticide contamination of soil and ground water at or near the agricultural fields is a major problem world wide. The ability of several amendments like rice straw, manure, saw dust and charcoal were used to stimulate the degradation of atrazine in soil.
