contributions of roots and organic matter to soil the root of the matter linking root traits and soil organic matter stabilization processes book summary abstract plant roots contribute substantially to the formation of stable soil organic matter (som), and there is evidence that species differ in their contribution to som stabilization. however, it remains unclear what specific root traits contribute to the three som stabilization

the microbial efficiencymatrix stabilization (mems while the stabilization mechanisms operate regardless of om origin, som stabilization can be indirectly promoted by microbial processing of plant material, through the beneficial effect of microbes on aggregate formation and subsequent effects on organomineral stabilization.

mineralization an overview sciencedirect topicsmineralization technologies have the advantage that they can also cocapture so x, no x and particulates, along with co 2, avoiding additional investment costs in scrubber or carbon capture units. carbonate products can be used in a variety of applications from agricultural fertilizer to aggregates, specialist construction materials to cements.

organic matter mineralization in different soil aggregate the mineralization rate of the organic matter (om) in the aggregate fractions of a gray forest soil separated by repeated sieving through sieves with different mesh sizes was assessed. the samples of the soil aggregate fractions were incubated for 141 days under constant temperature and moisture, and the cco 2 emission rate

activities of nitrogenmineralization enzymes associated aggregates of different sizes provide diverse microhabitats for microorganisms and therefore in uence soil enzyme activities. our objective was to test the hypothesis that activities of n mineralization enzymes increase with aggregate size and in notill compared with tilled systems.

aggregate and soil organic carbon dynamics in south recalcitrance of the soc did not appear to largely affect soc stabilization. statistical correlations between extractable amorphous al contents, aggregate stability and c mineralization rate constants were encountered, supporting this hypothesis.

carbon sequestration and mineralization in soil aggregates thus, evaluating soc mineralization and stabilization in aggregates is key to understand the mechanisms of longterm soc sequestration (rabbi et al., 2014). conventional tillage (e.g., moldboard plowing followed by secondary tillage operations) disrupts aggregates and reduces c sequestration (zhao et al., 2015, somasundaram et al., 2017).
