| dc.description.abstract | The effect of slow release fertilizers in coconut growing laterite soil by using different slow release N-carriers was evaluated. The results indicated that the Urea-N was maximum at the first day when fetilized with urea, whereas it was comparatively low for slow release sources. With the progress of time, the concentration of urea-N gradually decreased to a low value by the 15th day in urea, 60th day in neemcake coated urea and urea formaldehyde and 120th day in the case of coir dust coated urea. The ammoniacal-N was maximum for urea followed by coir dust and neemcake-coated urea. Urea formaldehyde treatment had relatively low NH4-N on first day and progressively increased upto 60 days. The NH4-N content showed a gradual decrease in the urea treated soils whereas a gradual increase from 1 to 120 days when treated with neemcake coated urea and coir dust coated urea. The nitrate nitrogen concentration progressively increased upto the 15th day in the case of other treatments. The present study reveals in general, the slow release nature of ureaformaldehyde and nitrification inhibition property of neemcake and coir dust. | en_US |
