Iron fertilizer: a small amount is not a small effect

Iron is the one with the highest content of trace elements in crops, and the highest content in crop roots, followed by lower leaves and stems. The role of iron in crops is to promote the formation of chlorophyll, promote the reduction of nitric acid in crop roots, and participate in the nitrogen fixation of leguminous crop root nodules. Although the amount of iron fertilizer is small, the effect is not small.

â‘ It is beneficial to the synthesis of chlorophyll. If there is no iron, chlorophyll is prone to disintegration. After the disintegration of iron-deficient chlorophyll, the leaves will appear severe chlorosis. This is more common in grape fields, such as a white flower of grape leaves. Just because of iron deficiency and without chlorophyll, plants cannot perform photosynthesis.

â‘¡Iron fertilizer can promote the metabolism of nitrogen fertilizer. Iron fertilizer and copper fertilizer play a role in promoting the conversion of nitrate nitrogen into ammonium nitrogen.

â‘¢ Iron is closely related to the redox process of crops, which is similar to the role of iron in the human body.

â‘£Iron can enhance disease resistance. It is very important to ensure that the iron fertilizer of the crops can enhance the disease resistance of the crops. If a certain amount of iron fertilizer is applied in the middle of June and early August, the disease resistance will be much enhanced. This will have a ****** effect on the ****** of Verticillium wilt.
