Secondary salinity effects on soil microbial biomass [PDF]
Biology and Fertility of Soils, 2010 Secondary soil salinilization is a big problem in irrigated agriculture. We have studied the effects of irrigation-induced salinity on microbial biomass of soil under traditional cotton (Gossypium hirsutum L.) monocul- ture in Sayhunobod district of the Syr-Darya province of northwest Uzbekistan.

BIOMASSA MICROBIANA E SUA CORRELAÇÃO COM A FERTILIDADE DE SOLOS EM DIFERENTES SISTEMAS DE CULTIVO
Colloquium Agrariae, 2010 The role of microorganisms in the soil is to mediate processes related to management the ecological balance. Thus, they can be sensitive indicators of changes in soil quality. Microorganisms have the ability to quickly respond to changes in soil quality,

Predictive model of soil molecular microbial biomass
Ecological Indicators, 2016 Abstract Preservation and sustainable use of soil biological communities represent major challenges in the current agroecological context. However, to identify the agricultural practices/systems that match with these challenges, innovative tools have to be developed to establish a diagnosis of the biological status of the soil.

Soil microbial biomass in organic farming system [PDF]
Ciência Rural, 2010 Agricultural production systems have to combine management practices in order to sustain soil's profitability and quality. Organic farming is gaining worldwide acceptance and has been expanding at an annual rate of 20% in the last decade, accounting for over 24 million hectares worldwide.

Microbial Biomass Responses to Soil Drying-Rewetting and Phosphorus Leaching
Frontiers in Environmental Science, 2019 Soil drying-rewetting is known to enhance soil phosphorus leaching, which in part is due to osmotic shock and lysis of microbial cells upon rewetting.

Tree species composition influences enzyme activities and microbial biomass in the rhizosphere: a rhizobox approach. [PDF]
PLoS ONE, 2013 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 ...
