Effect of Trace Element Fertilizer on Crops





Principle 1: In addition to a large number of elements such as nitrogen, phosphorus and potassium, crop growth and development also needs trace elements such as iron, boron, manganese, zinc, molybdenum and copper. They are components of a variety of enzymes in crops and have an important impact on promoting normal crop growth and development, improving disease resistance, increasing yield and improving quality.



Principle 2: Most of the trace elements in the soil are in an invalid state that is difficult for plants to absorb. Applying trace element fertilizer to the soil is also easy to be fixed by the soil.


Principle 3: Although the content of trace elements in crops is small, it plays a vital role in plant growth and development. It is a component of enzymes or coenzymes in plants. It has strong specificity and is indispensable and irreplaceable for crop growth and development. Therefore, when plants lack any trace elements, their growth and development will be inhibited, resulting in reduced yield and quality.



Principle 4:​ When the plant has sufficient trace elements, its physiological function will be very vigorous, which is conducive to the absorption and utilization of a large number of elements by crops, and can also improve the colloidal chemical properties of cell protoplasm, so as to increase the concentration of protoplasm and enhance the stress resistance of crops to adverse environment. With the continuous improvement of crop yield and the large application of chemical fertilizer, the application of trace element fertilizer is becoming more and more urgent.
