How feedback loops between meso- and macrofauna and organic residues contrasting in chemical quality determine decomposition dynamics in soils

open access: yesHeliyon, 2023
The concept of feedback loops between changes in chemical quality of decomposing organic residues and changes in faunal communities was employed in studying how such feedback loops, representing distinct ecological successional stages, determine ...

Is pre-biological treatment of organic wastes the best option for recycling organic matter to soil? [PDF]

open access: yes, 2004
Organic wastes are produced from a variety of sources such as agriculture, horticulture, forestry, industry, sewage treatment and households. These wastes are mainly derived from crops grown on land and contain elements, such as N, P, K, and S ...

SOIL ORGANIC MATTER (SOM): STATUS, TARGET AND CHALLENGES IN NEPAL [PDF]

open access: yesMalaysian Journal of Sustainable Agriculture, 2021
Changes in soil organic matter (SOM) are slow and difficult to monitor, usually apparent after few decades. Recent changes in the agriculture had its influence on soil, including the soil organic matter content.

Application of Remote Sensing in the Estimation of Soil Organic Matter Content

open access: yesChemical Engineering Transactions, 2018
This paper uses remote sensing technology to estimate the content of soil organic matter. It samples the soil, test its organic matter content, and analyzes the correlation between the reflectance of bands of various wavelengths and the content of ...

The Increase of Soil Organic Matter Reduces Global Warming, Myth or Reality?

open access: yesSci, 2021
The soil has lost organic matter in the past centuries. Adding organic matter to soils is one of the management practices applied to recover the levels of soil carbon of the past and to improve soil properties.

Possible role of organic matter in radiocaesium adsorption in soils [PDF]

open access: yes, 2002
The aim of this review is to examine the hypothesis that organic matter decreases the adsorption of radiocaesium on clay minerals. The factors that determine radiocaesium mobility and bioavailability in soil are briefly outlined to show why a ...

The effects of soil organic matter on seedling emergence in sunflower (Helianthus annuus L.)

open access: yesPlant, Soil and Environment, 2004
Seedling emergence is one of the most important factors in the establishment of optimum plant density for a maximum yield. Seed quality and seedbed conditions affect seedling emergence.

Study of the trace metal ion influence on the turnover of soil organic matter in cultivated contaminated soils [PDF]

open access: yes, 2006
The role of metals in the behaviour of soil organic matter (SOM) is not well documented. Therefore, we investigated the influence of metals (Pb, Zn, Cu and Cd) on the dynamic of SOM in contaminated soils where maize (C4 plant) replaced C3 cultures. Three

Modelling soil organic matter turnover [PDF]

open access: yes, 2004
This thesis investigates various ways of determining and predicting soil carbon quality. The continuous-quality theory was used to study soil carbon quality changes under perturbations and to explain soil C:N ratios. Also, using the framework of the same

Effect of different planting pattern arrangements on soil organic matter and soil nitrogen content under a maize/soybean strip relay intercropping system

open access: yesFrontiers in Plant Science, 2022
Assessing the spatial distribution of organic matter and total nitrogen in soil is essential for management and optimum utilization of fertilizers. Therefore, the present field experiment was conducted to evaluate the impact of different planting pattern
