tailieunhanh - Study of nitrogen release potential of Entisol and Vertisol as influenced by various sources of nitrogenous fertilizers

The experiment was conducted to study the nitrogen release potential of Entisol and Vertisolas influenced by the treatments of neem coated urea (NCU), DAP, NPK briquette, NP briquette, urea briquette and crotonylidene diurea (CDU). The application of all the sources of nitrogenous fertilizers increased the N release potential by % to % over the control in Entisol and by % to % over the control in Vertisol. The application of NCU in Entisol( mg kg-1 day-1 ) and the application of NPK briquette in Vertisol ( mg kg-1 day-1 ) showed the highest N release potential. The NPK briquette and NP briquette are identified as the best slow nitrogen releasing fertilizers followed by the neem coated urea and urea briquette. | Study of nitrogen release potential of Entisol and Vertisol as influenced by various sources of nitrogenous fertilizers
