In the micronutrient elements, except for chlorine, which is not lacking in the soil, several other nutrients Elements require the application of trace element fertilizers. Chemical fertilizers are fertilizers made by chemical methods that contain one or several nutrient elements needed for the growth of crops. The abbreviation of chemical fertilizers is called unit fertilizers that contain only one nutrient element that can indicate the content, such as nitrogen fertilizer, phosphorus fertilizer, Potassium fertilizers and minor macroelement fertilizers and trace element fertilizers, chemical fertilizers containing two or three of the three nutrients nitrogen, phosphorus, and potassium, and their contents can be indicated, are called compound fertilizers or mixed fertilizers.
