Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth. This over-fertilization by farmers, driven by the desire for higher yields, does not always contribute to high yield but it has recently become a common practice for farmers in China nonetheless. Unfortunately, over-fertilization decreases the efficiency of nutrient use and causes a series of economic and environmental problem. Careful use of fertilization technologies is important because excess nutrients can be detrimental. Fertilizer burn can occur when too much fertilizer is applied, resulting in damage or even death of the plant. Fertilizers vary in their tendency to burn roughly in accordance with their salt index.
