Aug 01, 2021  1. Introduction. Maintaining and increasing soil organic matter (SOM) contents is key to carbon (C) sequestration and climate change mitigation (Paustian et al., 2016).Apart from root exudates, plant litter is the major parent material for SOM formation (Kögel-Knabner, 2002).This litter enters the soil through the turnover of roots, via bioturbation, or as dissolved organic matter (DOM).

Plant Litter - an overview ScienceDirect Topics

Ground Litter. Plant litter represents a major source of organic carbon in forest soils (Anichkin and Tiunov, 2011; Berg et al., 2001). The decomposition of plant litter is a complex process that involves mineralization and transformation of organic matter. Decomposition of plant litter is a key step in nutrient recycling.

May 06, 2021  Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that govern its cycle are not well-described. To promote a holistic understanding of soil N dynamics, we need an integrated model that links soil organic matter (SOM) cycling to bioavailable N in both unmanaged and managed landscapes, including agroecosystems.

Building Soil Organic Carbon With Plant Roots

Building Soil Carbon. Typical soils range from 1-5% percent soil carbon by weight. Because of carbon cycling by microbes, building soil carbon is complex and does not simply equal the carbon inputs from roots and plant litter. Typically, we expect more degraded soils with lower carbon levels to have the capacity to build soil carbon faster, as ...
