Impact of Multi-Nutrient Briquettes on Movement of Nitrogen and Phosphorus in Soil

Abstract

Application of chemical fertilizers leads to the loss of soil fertility due to the imbalanced use of fertilizers which have adversely affected agricultural productivity and caused soil degradation. For sustainable agriculture scientific and efficient use of fertilizers is important. A number of investigators have shown that there is a definite and nearly constant requirement of nitrogen and phosphorus for the production of high yielding varieties of the crop. The movement of nutrient N was maximum in treatment receiving recommended dose of fertilizer through fertigation at all depths followed by the application of briquette in root rhizosphere. The movement of nutrient P was observed at a lower magnitude; however, the P movement was maximum in soluble fertilizers and briquettes.
