Zinc Sulfate/Zinc
Overview:
The white flower seedlings are easy to appear in maize due to zinc deficiency. When the zinc deficiency is serious, the seedlings will stop growing or even die.
Especially for some sandy loam soil or fields with high pH value, zinc fertilizer such as zinc sulfate should be applied. The increase of zinc fertilizer also has the effect of increasing yield.
