The N, P, S, K, Ca, Mg is an essential nutrient mineral elements in plants. C is a basic element. Main elements: refers to the former 6 kinds of elements in a large number of elements, namely C, H, O, N, P, S, accounting for about 97% of the total plasma. Mineral elements: except C, H, O, the main absorption from the soil by the root element. The essential elements required for plant life elements. It must meet the following conditions: first, due to the lack of this element, plant growth disorders, cannot complete life history; second, removal of the elements show specific deficiency, and this deficiency can be prevented and recovery: Third, the element should show direct effect on plant nutrition physiology, indirect the effect is not due to physical, chemical and microbiological conditions of soil or mediu
