Organic Amendment Effects on Microbial Population and Microbial Biomass Carbon in the Rhizosphere Soil of Soybean

Soil Quality Parameters and Yield of Green Gram as Affected by the Combined Application of Manures and Biofertilisers

“…Addition of organic manures increases the microbial biomass carbon because the organic manures act as a good substrate that provides a congenial environment for the microbial growth. Supply of readily available C resulted in higher microbial activity and ultimately higher microbial biomass in soil (Das and Dkhar, 2012). The results are also in close conformity with the findings of Das and Dkhar (2011) who have reported that the application of organic manures enhanced the microbial biomass carbon as compared to inorganic fertilisers and control.…”

Lignite amendment has limited impacts on soil microbial communities and mineral nitrogen availability

“…This supports the hypothesis that lignite is a relatively stable organic amendment, as microbial growth was not observed despite the large carbon input. As such, lignite shows more similarities to biochar amendments whose impacts on microbial biomass are slight (Watzinger et al, 2014), than compared with more nutrient-rich composts, animal or green manure, which tend to increase microbial biomass (Das and Dkhar, 2012;Peacock et al, 2001;Stark et al, 2008). Nevertheless, there were significant changes in microbial community composition at 30 and 60 d after lignite and urea application as demonstrated by PLFA composition.…”

Effect of agro industrial wastes compost on soil health and onion yields improvements: study at field condition

“…Most of the treatments showed an increment in pH after compost application. This increment in pH after compost amendment could be explained by decomposition of organic products release of K + , Ca 2+ and Mg 2+ (Das and Dkhar 2012) and OH − to the soil in resulting slight increase in the soil pH. Soil treated with 10 kg h −1 , 20 kg h −1 and 60 kg h −1 compost showed insignificant increment in electrical conductivity (p > 0.05).…”
