Methodological choices in size and density fractionation of soil carbon reserves - A case study on wood fiber sludge amended soils.

Soil organic carbon (SOC) is in the focus of research due to its central role in regulating climate and maintaining fertility and resilience of soils. Methodologically, shifting from whole soil C measurements to specific SOC fractions increases possibility to detect small changes in the vast SOC storage, and enhances estimation of SOC stability. However, SOC fractionation schemes are numerous and variable.

Slow pyrolysis liquid in reducing NH emissions from cattle slurry - Impacts on plant growth and soil organisms.

A substantial percentage of manure nitrogen (N) can be lost as gaseous ammonia (NH) during storage and field spreading. Lowering slurry pH is a simple and accepted method for preserving its N. Efficiency of slow pyrolysis liquid (PL) produced from birch (Betula sp.
