Different organic manures and inorganic sources of phosphorus as influenced on nutrient availability in calcareous soil

Author(s): Padghan GV, Kamble BM, Gajbhiye PN and Nakhate PR
Abstract: A laboratory incubation experiment of 90 days was carried out at Division of Soil Science and Agricultural Chemistry, RCSM College of agriculture, Kolhapur under MPKV, Rahuri, during 2021-22 to study the effect of organic manures on chemical properties viz. pH, EC, Organic carbon, CaCO3, Available N,Available P, Available K and micronutrients DTPA Fe, Zn, Mn and Cu. The experiment was laid out in a Factorial Completely Randomized Design (FCRD) with three replications and fifteen treatments combination of organic and inorganic fertilizers. The treatment comprised of Control, FYM, VC, POL, PMC, SSP, DAP, SSP+ FYM, SSP +VC, SSP + POL, SSP + PMC, DAP+ FYM, DAP+VC, DAP+ POL, DAP+ PMC. The results indicated that incorporation of organic manures and inorganic fertilizers to soil significantly influenced soil properties. Among organic manures the treatment receiving PMC recorded significantly lowest pH (8.20). However, it was at par with POL (8.22). The significantly highest EC was recorded with the application of all organic manures. The soil pH decreases whereas, the electrical conductivity increases due to application of organic manure alone or in combination with inorganic fertilizer. The organic carbon content in soil remains unaffected while the calcium carbonate level decreases gradually due to soil treatment with organic, inorganic or in combination. The soil nutrient status including major (N, P and K) and micronutrients (Fe, Zn, Mn and Cu) improved due to organic manure and combination treatments. DAP as an inorganic source of phosphorus was beneficial in increasing availability of nitrogen, potassium, zinc and manganese, iron alone or in combination with PMC and POL.
