Abstract:

Knowledge of the nutrient release from organic residues helps in optimizing nutrient effciency in agricultural crop production systems. A laboratory incubation experiment was conducted in Completely Randomized Design to assess the release of Ammonical-N, Nitrate-N, available Phosphorus and Potassium in soil incubated with two organic sources viz. farmyard manure and pressmud compost (T0= Control, T1= 5 MT ha-1 organic manure, T2=10 MT ha-1 organic manure, T3= 15 MT ha-1 organic manure, T4=20 MT ha-1 organic manure) at different days (0,30,60,90,120) after incubation under controlled aerobic condition. The study revealed that NH4-N content showed decreasing while NO3-N showed increasing trends whereas available phosphorus and potassium content increased from 0 to 30 DAI and then decreased gradually up to 120 DAI.


Keywords: Farmyard manure, Pressmud compost, Incubation, Ammonical-N, Nitrate-N, available Phosphorus and available Potassium
