Effect of Crop Residues on Weed Emergence [PDF]

Agronomy, 2021
Weed behaviour in crop fields has been extensively studied; nevertheless, limited knowledge is available for particular cropping systems, such as no-till systems. Improving weed management under no-till conditions requires an understanding of the interaction between crop residues and the seedling emergence process.

Linking changes in the soil microbial community to C and N dynamics during crop residue decomposition

Journal of Integrative Agriculture, 2021
Crop residues are among the main inputs that allow the organic carbon (C) and nutrients to be maintained in agricultural soil. It is an important management strategy that can improve soil fertility and enhance agricultural productivity. This work aims to

Changes in chemical composition of cover crops residue during decomposition

Ciência Rural, 2021
: Crop residues decomposition are controlled by chemical tissue components. This study evaluated changes on plant tissue components, separated by the Van Soest partitioning method, during cover crop decomposition.

Production of indigenous mushrooms spawn using crop residues as substrates [PDF]

, 2022
Indigenous oyster mushrooms occur naturally when conditions are favourable. Achieving good quality spawn is a major challenge to small-scale farmers in Kenya, who strive to domesticate indigenous mushrooms.

Obtaining more benefits from crop residues as soil amendments by application as chemically heterogeneous mixtures [PDF]

, 2020
Crop residues are valuable soil amendments in terms of the carbon and other nutrients they contain, but incorporation of residues does not always translate into increases in nutrient availability, soil organic matter (SOM), soil structure, and overall ...

Soil physical and chemical quality as influenced by soil tillage managements under double cropping rice system of southern China

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020
This study aimed to determine short-term effects of soil tillage and crop residues on soil quality and grain yield of rice in a double-cropping paddy field of southern China. The experiment included four soil tillage treatments: conventional tillage with

Roots contribute more to refractory soil organic matter than above-ground crop residues, as revealed by a long-term field experiment [PDF]

, 2011
We revisited the well documented and ongoing long-term 'Ultuna continuous soil organic matter field experiment' which started in 1956 at the Swedish University of Agricultural Sciences.

A methodology for estimating the ammonia emission from crop residues at a national scale

Atmospheric Environment: X, 2019
Crops and crop residues contribute to pollution of the environment by ammonia (NH3) volatilization. This study focusses on the volatilization from crop residues, defined as residues after a management action or frost i.e.
