Integrated effects of vermicompost, climatic factors and soil mixing on selected soil fertility indicators

A field experiment was carried out to investigate the effects of vermicompost (0, 10, and 15 tha-1), climatic elements i.e. soil moisture (50%, 70%, 100%) elevation temperature (1 20C) on physico-chemical properties nutrient availability post-harvest calcareous-acid mixed soils after rice production. total 18 treatments assembling afore-mentioned doses applied. The analyses demonstrated significant variation in (p ≤0.05) both available status physicochemical soils. Except for sulfur; pH, EC, organic carbon (OC), nitrogen, phosphorous, potassium, calcium, sodium were detected higher amounts 1:1 (calcareous : acid-soils) than those 1:3 counterpart initial conditions. highest levels OC, P Zn determined treatment T13. Whereas, T6 proved be best dose Ca Mg. T1, T2, T11, T16 recorded have lower N, P, Ca, Mg, S contents In particular, Na found lesser all subplots. a nutshell, most exerted favourable influence maintaining healthy level parameters owing their inherent characteristics.
