The Crucial Role of Soil Organic Matter in Satisfying the Phosphorus Requirements of Olive Trees (Olea europaea L.)

Agriculture, 2021
Under high organic matter content, even under low extractable soil P concentrations, sufficient or over-sufficient foliar P levels may be found. This multi-year study aimed at examining the effects of organic matter content and irrigation management on ...

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

, 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 ...

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 ...

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 ...

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 ...
