| Abstract: | Using15 N tracer technique, the fate and efficiency of nitrogen in supergranules of urea as compared with that in powdered urea were studied in rice fields. The results obtained show that supergranules of urea were characterized by the slight N loss and high N recovery as well as by delayed but long lasting fertilization effects. It follows that the supergranules should be applied earlier and at a lower rate as compared with powdered urea. |
