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 ...

Plant litter - Wikipedia

Litterfall, plant litter, leaf litter, tree litter, soil litter, or duff, is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground.This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic").
