Microbial biomass in paddy soil [PDF]
The authors investigated the role of microorganisms in paddy soil ecosystems and the influence of fertilizer and manure applications on the soil microbial biomass in paddy soils based on direct count using a fluorescence microscope. The results are summarized as follows.

Tree species composition influences enzyme activities and microbial biomass in the rhizosphere: a rhizobox approach. [PDF]
Monoculture causes nutrient losses and leads to declines in soil fertility and biomass production over successive cultivation. The rhizosphere, a zone of usually high microbial activities and clearly distinct from bulk soil, is defined as the volume of ...

Soil Microbial Biomass Across a Gradient of Preserved Native Cerrado
The different physiognomies and soil conditions across the Cerrado gradient may influence soil microbial biomass. The present study evaluated the soil microbial biomass and enzyme activity across a preserved Cerrado gradient and correlated these with ...

Biobased Materials from Microbial Biomass and Its Derivatives [PDF]
There is a strong public concern about plastic waste, which promotes the development of new biobased materials. The benefit of using microbial biomass for new developments is that it is a completely renewable source of polymers, which is not limited to climate conditions or may cause deforestation, as biopolymers come from vegetal biomass.

Change in soil microbial biomass along a rural-urban gradient in Varanasi (U.P., India)
Soil microbial biomass has been used as an early indicator of change in soil properties resulting from urbanization. We analyzed the effect of urbanization along a rural–urban gradient on soil microbial biomass and physico-chemical properties of the soil.

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