Abstract:

The long-term application of excessive chemical fertilizers has resulted in the degeneration of soil quality parameters such as soil microbial biomass and nutrient content, which in turn affects crop health, productivity, and soil sustainable productivity. Organic manuring and Integrated nutrient management system (INMS) gained importance in maintaining the soil health and fertility. The continuous application of vermicompost (VC) for ten years @ 15t /ha under wheat-guar cropping system at Bawal in sandy soils had beneficial effects on soil microbiological properties compared to conventional system using only chemical fertilizers. Organic C and total N increased from 0.163 to 0.270 and from 0.012 to 0.076%, respectively. The total P, available P and available N were 152, 8.0 and 29 mg/kg soil, respectively. The amount of total K varied from 1530 to 2019 and Zn from 126 to 175 mg/kg soil. The C mineralization rate and potentially mineralizable nitrogen were 6.8 and 41.5 mg/kg soil, respectively and were highest in treatment receiving VC @15t /ha. Microbial biomass C (MBC), microbial biomass N (MBN) and microbial biomass P (MBP) were 320, 40 and 12 mg/kg soil. The biomass C/N ratio ranged from 6.4 to 8.0 and C/P ratio from 20.0 to 26.6, and was highest treatment with VC @15t /ha.
