Slow release fertilizers are fertilizers with high nutrient content, releasing nutrients for each stage of development and growth of plants. Slow-release fertilizer to help farmers not fertilizer supplement other single fertilizers to meet the development needs of the crop. With the NPK fertilizers produced by old technology materials and NPK fertilizer plant very quickly dissolved when not promptly absorb the necessary nutrients have been leached. This kite wasteful and expensive for farmers. Furthermore, NPK melt will generate polluting weeds and soil toxicity.

Through many studies have shown that when using slow release fertilizer, economic efficiency is improved remarkably. Immediate effectiveness can easily see the cost farmers invest significantly reduced; specifically, farmers fertilize only a slow release NPK fertilizer by about 70% compared with the annual average amount of yield and increased 8.0% compared with the control area. In addition, when using slow release NPK fertilizer will reduce the cost of hiring fertilizer, transportation and warehousing relieved area. Moreover, caring for plants with slow release fertilizer to the soil to help retain moisture, reduce the amount of toxins in the soil and environment friendly.
