What is it about?
The present investigation entitled “Effect of Phospho compost and Nitrophospho-Sulpho compost on soil chemical and biological properties under soybean in Vertisols" was conducted at Research farm, Dr. PDKV, Akola during Kharif 2016. The experiment was laid in Randomised Complete Block Design with eight treatments and three replications. The treatments used were control,100% Recommended Dose of fertilizers (RDF) [30:75:30 NPK/ha] in form of Diammonium Phosphate and Muriate of Potash, 50% P through Phospho Compost +Remaining RDF through mineral Fertilizers, 25% P through Phospho Compost +Remaining RDF through mineral fertilizers, 50% P through Nitro PhosphoSulpho compost +Remaining RDF through mineral Fertilizers, 25% P through Nitro PhosphoSulpho compost +Remaining RDF through mineral Fertilizers,100% P through Phospho Compost, 100% P through Nitro PhosphoSulpho compost. An organic source like Phospho compost and Nitrophospho- Sulpho compost were applied. The result revealed available nutrient status of Nitrogen (253.60 Kg ha-1) Sulphur (15.73 mg Kg-1) were recorded the highest values significantly under 100% application of P through Nitrophospho-Sulpho compost, numerically higher available P (21.77 Kg ha-1) with 25% P through Nitrophospho-Sulpho compost + remaining RDF through mineral fertilizers and available K (407.29 Kg ha-1) was recorded with 100% RDF. In case of biological properties Soil Microbial Biomass Carbon (227.85 and 230.60 mg Kg-1), Soil Microbial Biomass Nitrogen (43.90 and 47.20 mg kg-1) at flowering and pod formation stage of soybean 100% P through NPS recorded highest values respectively. Hence, the combination of organics and inorganics showed better soil available nutrients and biological properties

Why is it important?
soil health point of view its important
Perspectives
The present investigation will be helpful in monitoring effect of phospho-compost and nitrophospho-sulpho compost on soil enzymatic activity and yield of soybean. Combined application of manures and fertilizers improves enzymatic activity, soil health and productivity of crop. Use of organics like composts plays a role to improve the biological activity and soil health. It will be benefit to farmers , extension personnels and research workers to have combination of organics with inorganics to obtain sustainable yield and maintain soil health for long time.
