The Potential of Biochar Made from Agricultural Residues to Increase Soil Fertility and Microbial Activity: Impacts on Soils with Varying Sand Content

Agronomy, 2021
Different types of soil respond variably to biochar amendment. Soil structure and fertility are properties which strongly affect the impacts of biochar on soil fertility and microbial activity.

Effects of heavy metals on soil microbial biomass carbon [PDF]

MOJ Biology and Medicine, 2019
This study was aimed at evaluating the effect of heavy metals on soil microbial processes. The effects of Lead (Pb) and Cadmium (Cd) at different concentrations were investigated over a period of eight weeks. Chloride salts of Pb and Cd were added singly and in combination to soil samples at room temperature (270C) in different polythene bags.

Microbial responses to doses of cover plant straw in cerrado piauiense oxisol

Bioscience Journal, 2020
Carbon and nitrogen from the soil microbial biomass play a significant role in the rotation of C and N, and promote nutrient cycling. Thus, the objective of this study was to evaluate changes in the soil microbial biomass with growing doses of cover ...

The changes in microbial biomass C and N in long-term field experiments

Plant, Soil and Environment, 2008
Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. A positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in ...

Short-term winter snow reduction stimulates soil nutrient leaching without changing the microbial biomass in an alpine fir forest

Global Ecology and Conservation, 2021
Winter snowpack maintains a relatively warm environment for soil microorganisms and modulates soil biogeochemical cycles in cold ecosystems; however, snowpack reduction induced by climate warming may change soil dissolved nutrient leaching and microbial ...

Soil Microbial Biomass And Activity In A Cork Oak Savanna [PDF]

, 2010
Cork oak savannas are composed by a sparse tree canopy (30-70 trees/ha) and a grassland understory predominantly composed of C3 annuals that survive the hot and dry Mediterranean summers as seeds in the soil.

Representation of Dormant and Active Microbial Dynamics for Ecosystem Modeling [PDF]

, 2013
Dormancy is an essential strategy for microorganisms to cope with environmental stress. However, global ecosystem models typically ignore microbial dormancy, resulting in major model uncertainties.
