Weather disturbances such as torrent with consecutive drought soil degradation or erosion and organic matter not so much. The efficiency of chemical fertilizer, the more will go lower. Chemical fertilizer will accelerate the degradation rate of the organic matter to the structure of clay and decay is not hard to absorb water. The chemical fertilizer containing nitrogen too much will make the soil is acid. The use of chemical fertilizer core element (N P K) of each other will cause problems such as the lake of secondary element of iron, zinc, copper, manganese, magnesium. Farmers invest increased use of chemical fertilizers to maintain productivity, affecting the production cost and prices of agricultural products due to the uncertain. Chemical fertilizer also affect health, such as causing skin irritation, toxic residues in the output. Chemical fertilizer didn’t result only in agriculture, but also affects the climate of the world, especially nitrogen oxides gas (N2O) which will destroy the ozone layer, which serves to absorb and filter wave infrared.
