Abstract
Controlled release technology is one of the most efficient techniques to reduce environmental hazards accompanied with fertilizers and herbicides. In the present work, new formulations for controlled release of urea fertilizers were prepared based on biodegradable polymers and agricultural waste. The release behavior of urea fertilizer from the superabsorbent composite was estimated using UV/Vis spectrophotometer. The effect of the pH of the soil on the release rate was also investigated.
