Iron fertilizer: Although the amount of use is not small

Iron is the most abundant trace element in crops. It has the highest content in crop roots, followed by the lower leaves and stems. The role of iron in the crop body is to promote the formation of chlorophyll, promote nitric acid reduction in the roots of the crop, and participate in nodules nitrogen fixing of legumes. Although the use of iron fertilizer is small, the effect is not small.

2 Iron fertilizer can promote the metabolism of nitrogen fertilizer. Iron and copper fertilizers play a catalytic role in the conversion of nitrate nitrogen to ammonium nitrogen.

3 Iron is closely related to the redox process of crops. This is similar to the effect of iron in human body.

4 Iron can enhance disease resistance. It is very important to ensure that the iron fertilizer of crops enhances the disease resistance of crops. If a certain amount of iron fertilizer is applied in mid-June and early August, the disease-resistance capability will be greatly enhanced. This will have a significant effect on the treatment of Verticillium wilt.
