Microbial biomass-C determined using CaCl2 and K2SO4 as extraction reagents

Plant, Soil and Environment, 2005
Microbial biomass-C [MBC] was determined by re-hydration [RHD] technique using two very similar salt solutions in dissociation potency (0.5 mol/l K2SO4 [MBC-K] and 0.01 mol/l CaCl2 [MBC-Ca]) in forest, grassland, arable Cambisols [Inceptisols] and ...

Effect of a Trench Combined With Exclosure on Recovery of Herbaceous Biomass in Degraded Mountain Areas in Hawasa Watershed, Southern Ethiopia

Land Degradation &Development, EarlyView.
ABSTRACT The objective of this study was to evaluate the restoration of herbaceous biomass in degraded mountain lands by comparing the impact of trenches established alongside exclosures (EX‐SWC) to exclosures alone (EX). To achieve the objective, herbaceous biomass was collected from areas restored using EX‐SWC and EX over three consecutive years ...
