Zinc chelates are often used in agriculture as a source of zinc for plants. They are particularly useful in soils with high pH levels, as zinc is less available to plants in alkaline soils. Zinc chelates are also used as a foliar spray, which allows the zinc to be absorbed directly by the plant leaves.

Zinc chelates are organic compounds that contain zinc ions bonded to organic molecules. These organic molecules act as a carrier for the zinc ions, protecting them from binding with other soil elements that could render them unavailable to the plant. The organic molecules also help to increase the mobility of the zinc, allowing it to move more easily through the soil to the plant roots.

Zinc chelates are often more effective in delivering zinc to plants, particularly in soils with high pH levels. They are also effective in treating zinc deficiency in plants, which can lead to stunted growth, reduced yields, and poor crop quality.

Overall, zinc chelates are a valuable tool in agriculture for ensuring that plants have adequate access to this important micronutrient, particularly in soils that are deficient or have high pH levels.
