Abstract: Slow release fertilizers are designed to enhance crop yield and minimizing the loss of nitrogen (N) to environment. However, N release in leaching and loss in ammonia emission from bag controlled release fertilizers have not been previously evaluated under the standardized conditions in soil. Accordingly, a laboratory study was conducted to evaluate the c...

This dispersion, sometimes occasional, sometimes by the influence of man, reaches proportions today that, in some cases, affect the development of natural ecosystems and their sustainability. Thus, becomes imperative t...
