Abstract:

The present investigation was carried out to study the effects of long-term application of inorganic fertilizers and organic amendments on soil organic matter level, soil biological properties and plant nutrient reserves. The continuous application of organic amendments for the last ten years under cotton-wheat cropping system at CCS H.A.U, Hisar had beneficial effects on soil chemical, arginine ammonification and nitrification activity as compared to application of chemical fertilizers. The soil pH ranged from 7.02 to 7.60. The electrical conductivity (EC) of soils increased from 0.24 to 0.40 dS/m. The organic carbon increased from 0.359 to 0.689% with application of phosphor-vermicompost + N through organic source. Total P (Phosphorus) varied from 80.2 to 179.3 and available P from 20.9 to 37 mg/kg soil with the application of phosphovermicompost + N through organic source. Arginine ammonification activity ranged from 0.52 to 1.02 µg NH4+- N/g soil/h and nitrification from 21.2 to 84.0 µg NO3-- N/g /day and were found highest in treatments with 75% RDN through vermicompost + Azotobacter + P requirement through rock phosphate and were lowest with inorganic fertilizers.
