Nutrient losses due to leaching, volatilization and fixation and the activated risk of nitrate leaching after fertilizer addition to the soil may be reduced through the use of slow-release fertilizers. Turmeric, a long duration and high yielding commercial crop consumes greater amount of nutrients from the soil as well as from applied fertilizers for a prolonged period. A field experiment was c...

Slow-release fertilizers are gaining acceptance to increase fertilizer use efficiency and reduce environmental impact. The release of nitrogen from methylene urea, a common slow release N fertilizer, is controlled by microbial decomposition. An enzyme hydrolyzing slowrelease nitrogen fertilizer, methylene urea, was purified from Rhizobium radiobacter (Agrobacterium tumefaciens) to homogeneity u...

This research aims to formulate and characterize the alginate-starch micro beads as a slow release urea fertilizer, using CaCl2 extrusion technique. experiment also investigates effect of alginate starch composition on color, swelling ratio, biodegradability, entrapment efficiency release. The result study showed that turned darker in color diameter its wet dry ranges between 3.18-3.40 mm 1.12-...
