ABSTRACT

The neem bark powder coated urea fertilizer samples were prepared by adapting the spray technique and characterized by using FT-IR and SEM studies. Incubation study was carried out to study the Nitrogen-release pattern with the help of Micro kjeldahl method. SEM studies revealed the presence of Neem bark powder coating on urea. The increase in percentage of coating showed a slow nitrogen-release pattern holding the promise for further studies in this line.
