Organic Amendments for Pathogen and Nematode Control

Annual Review of Phytopathology, 2020
The loss of methyl bromide as a soil fumigant and minimal advances in the development and registration of new chemical fumigants has resulted in a resurgence of interest in the application of organic amendments (OAs) for soilborne plant pathogen and plant-parasitic nematode management. Significant progress has been made in the characterization of OAs,

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 transformation and dynamics of microorganisms under different organic amendments

Science of The Total Environment, 2021
Organic amendments (OAs) application is a practical strategy to improve soil organic carbon (SOC) in agriculture. The present study evaluated the impact of different OAs on the transformation of carbon and the dynamics of microorganisms in a 77-day incubation experiment.

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)

Changes in soil organic matter chemical properties after organic amendments

Chemosphere, 2007
Organic inputs are used to improve soil physical and chemical properties, but the corresponding changes in soil organic matter (SOM) chemical properties are not well known. In this study, we compared some characteristics of the SOM of a soil receiving either no organic inputs, or two different amendments during 15 years (straw or conifer compost ...

L-glutaminase Activity of Organic Amendments

2011
High contents of organic matter are present in composts of urban wastes, part of which are easily hydrolysable and mineralisable by soil microorganisms. The metabolic use of this organic fraction depends on the activity of hydrolytic enzymes produced by soil microbial communities, especially those related with N cycle, in which L-glutaminase plays an ...

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.

Crop Residue Management and Organic Amendments

2017
Cultural practices like the type and quantity of crop residues and incorporating organic amendments to soil have a direct impact on plant health and crop productivity. These practices influence the release of biologically active substances from both crop residues and soil microorganisms.

Organizing to Amend Antidiscrimination Statutes in Maryland

Journal of Gay & Lesbian Social Services, 2004
SUMMARY Federal law and statutes in most of the 50 states prohibit discrimination in housing, employment, and public accommodations on the basis of race, creed, sex, and national origin. However, only 12 states and the District of Columbia have statutes which include prohibitions of discrimination based on sexual orientation.
