The effects of grinding on microbial and non-microbial ...

Grinding killed about a quarter of the biomass in both soils. Carbon from killed organisms accounted for a quarter of the extra CO2–C evolved after grinding in the arable soil and almost half in the grassland soil. The extra non‐biomass organic matter decomposing after grinding amounted to about 0.5% of the soil organic carbon in both soils.

2019-10-24  Conversion of soils supporting native vegetation to agricultural production has led to a loss of soil carbon stocks. Replacing a portion of the lost stocks will sequester atmospheric carbon with the concurrent benefit of enhancing soil sustainability. The ability of the fine fraction of soils (≤50-µm fraction) to adsorb organic carbon (OC) is considered a key mechanism capable of ...

2020-1-8  Phosphorus (P) is an essential, non-replaceable nutrient in biology, with finite global reserves. Whereas soils may contain pools of P that could be several thousand times higher than required for plant growth, only a small soluble fraction is available for plant uptake (Smil 2000; Sohrt et al. 2017).This is due to complex edaphic processes and interactions with soil components such as iron ...
