dc.description.abstract | The investigation on the impact of crop rotation on soil fauna in organic farming ecosystem was carried out at the ZARS, University of Agricultural Sciences, GKVK, Bangalore, during 2013. Soil application of 20 tonnes of FYM/ha+introduction of native fauna recorded significantly higher soil mesofauna, soil total Acari, cryptostigmatids, other Acari, other invertebrates and macro fauna like ants and beetles compared to other treatments during the cropping season. The highest population of total soil mesofauna was noticed 105 days after germination. Application of 20t of FYM ha"' significantly increased the soil organic carbon content(0.82%), available phosphorous(68.80 Kg/ha), available potassium(314.36 Kg/ha), exchangeable calcium(6.58 meq/lOOg), exchangeable magnesium(3.58 meq/lOOg), microbial biomass carbon(l 10.90 pg /g), microbial biomass nitrogen(10.87 pg /g), Dehydrogenase (296.37pg TPF/ g soil). Acid phosphatase (32.57pg PNP/ g soil). Alkaline phosphatase (15.77pg PNP/ g soil) and urease(l 11.54pg NH4"'/ g soil) in the soil compared to recommended fertilizer alone treatment. The same treatment also recorded higher plant biomass, root biomass, Rhizobium nodulation and grain yield(16.01 q/ha) compared to recommended package practices (12.90 q/ha) and recommended fertilizer alone(11.48 q/ha). Soil mesofauna abundance recorded a significant positive relationship with available phosphorus, exchangeable calcium, exchangeable magnesium, soil pH, microbial biomass carbon, Dehydrogenase and urease. Abundance of mesofauna played an important role in the formation of available phosphorus, potassium. Ex calcium. Ex magnesium and alkaline phosphatase. Soil moisture and atmospheric minimum temperature showed significantly positive and negative relationship with the abundance of soil mesofauna. These factors together with rainfall exhibited significant influence on the abundance on the mesofauna(67%). | en_US |
