Soil organic matter protects US maize yields and lowers crop insurance payouts under drought

Environmental Research Letters, 2021
Higher levels of soil organic matter improve soil water retention, meaning they could mitigate agricultural yield losses from drought. Yet evidence to support such claims is mixed and incomplete.

Rhizodeposition and litter decomposition of Phragmites australis play important roles in composition and properties of soil dissolved organic matter

Ecological Indicators, 2022
The dynamics of composition and properties of dissolved organic matter in soil depend on plant carbon inputs and microbial degradation. However, uncertainties remain regarding the relative contributions of different plant carbon inputs sources, i.e ...

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 ...

The turnover of organic matter in soil [PDF]

Biochemical Journal, 1968
There is little quantitative data on the turnover of soil organic matter even for parts of the world where long-term field experiments have been carried out. Comparisons of turnover under different climatic conditions, under different systems of agriculture, under different plant associations, at different pH's, in soils differing mechanical ...

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

A Method of Soil Moisture Content Estimation at Various Soil Organic Matter Conditions Based on Soil Reflectance

Remote Sensing, 2022
Soil moisture is one of the most important components of all the soil properties affecting the global hydrologic cycle. Optical remote sensing technology is one of the main parts of soil moisture estimation.

Pyrolysis Dynamics of Biomass Residues in Hot-Stage

BioResources, 2015
Original data for mass, element, and methane dynamics under controlled pyrolysis are presented for several biomass feedstocks. The experimental system consisted of an environmental (low-vacuum) scanning electron microscopy (ESEM) with a hot-stage and ...

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.
