Abstract:

An incubation experiment was conducted to study the release pattern of nitrogen fractions in Entisol and Vertisol as influenced by the various sources of nitrogenous fertilizers viz. neem coated urea (NCU), DAP, NPK briquette, NP briquette, urea briquette and crotonylidene diurea (CDU). The total N content was ranged from 16.10% N in DAP to 43.05% N in NCU among the various fertilizers. The NH4+-N was highest at zero day of incubation (DOI) and then showed continuous decreasing trend up to 90 DOI. The NCU and CDU showed higher amount of NH4+-N in Entisol while DAP, NPK briquette, NP briquette, and UB showed higher amount of NH4+-N in Vertisol. The release pattern of NO3--N showed steady increasing trend from zero to 75 DOI. The NCU and CDU showed relatively better performance in Entisol whereas the DAP and briquette fertilizers showed relatively better performance in Vertisol. Similarly the mineral N showed steady increase from zero to 75 DOI except at 45 DOI. The Vertisol released the higher amount of mineral N than Entisol. The briquette fertilizers and NCU maintained higher release rate of mineral N in both of the soils for longer period of time. Among the different nitrogenous fertilizers, NPK briquette and NP briquette are identified as the best slow nitrogen releasing fertilizers.
