Saha D.
Oil cakes are the residues left after extraction of oil from oil seeds, which occupy an important position in agricultural economy of India. Oil cakes obtained as by-product of oil mills are mostly used as cattle feed and manure. The manurial value of cakes lies mainly in their N-content although, they contain small quantity of P2O5 and K2O. Knowledge of N-mineralization from organic matter was obtained from studies that measured only the net change in the amount of exchangeable NH4+ and soluble NO3- in the soil.
