Differential Effects of Organic Amendments on Maize Biomass and Nutrient Availability in Upland Calcareous Soil

The current study is focuses on a sustainable agricultural ecosystem for soil fertility and human health improvement. To estimate the effects of applying organic amendments (compost, vermicompost, biochar, manure rapeseed cake) crop growth maize nutrient uptake in calcareous soil, eleven treatments were studied, which included compost (CM), cow vermicompost (CMV), pig (PMV), biochar (BCV), (BC), conventional synthetic fertilizers (NPK), CMV addition to NPK (CMV + NPK), PMV (PMV (OM), cake (RC) control without any fertilization (CK). Maize above belowground biomass analyzed glass greenhouse experiments. results showed that nitrogen carbon contents significant differences among treatments. Vermicompost significantly higher as compared inorganic except RC. All also better availability CK. In conclusion, with all substrates are recommended application fertilizers. Our will help promote alone or combination rather than only environmental sustainability.
