Land–Use Changes Influencing C Sequestration and Quality in Topsoil and Subsoil

Agronomy, 2019
Soil capacity as a major carbon (C) sink is influenced by land use. Estimates of soil organic carbon (SOC) sequestration have mostly focused on topsoils [0−30 cm official Intergovernmental Panel on Climate Change (IPCC) soil depth]. We investigated

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

Heliyon, 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 ...

Impact of Soil Organic Matter Content on Soil Moisture and Temperature at Different Depths in the Central Qinghai-Xizang Plateau

Gaoyuan qixiang, 2022
Soil organic matter content is relatively high in the central and eastern Qinghai-Xizang Plateau， which may change the soil hydrothermal properties and thus affect the transport of soil water and heat.However， there is still a lack of systematic ...

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

Malaysian 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.

PEMETAAN BAHAN ORGANIK TANAH PADA SAWAH IRIGASI DAN TADAH HUJAN DI KECAMATAN TUREN, MALANG

JTSL (Jurnal Tanah dan Sumberdaya Lahan), 2020
Each land use has a different vegetation density and the litter input as a source of soil organic matter. Vegetation density index can be analyzed based on the NDVI equation using the GIS approach.
