Abstract

Urea fertilizers are widely used in agriculture as they are an affordable and effective source of nitrogen for plant growth. However, they can also have negative impacts on the environment, as they release ammonia that can contribute to air and water pollution. To address this issue, this project investigates the potential of using cassava starch as a binder to slow the release of ammonia from urea fertilizers. The study aims to determine the effect of different ratios of cassava starch and urea fertilizer in urea granules on the growth of corn seedlings. Three types of urea granules with varying ratios of cassava starch and urea were used in the experiment. The growth of corn seedlings treated with these granules was observed and measured over 65 days. The results showed that the optimum ratio of cassava starch and urea was 48% urea concentration and 2wt% cassava starch concentration. Urea granules with this ratio resulted in reduced release of ammonia and pH value, which in turn promoted the growth of corn seedlings. These findings suggest that cassava starch can effectively slow the release of ammonia from urea fertilizers while promoting plant growth. The use of cassava starch as a binder in urea fertilizers can potentially have positive impacts on the environment. The study contributes to the limited research on the use of cassava starch as a binder in urea fertilizers, and further research can explore its potential in other types of fertilizers and its long-term effects on plant growth and soil health.
