Usage of agricultural grade zinc sulfate

Agricultural grade zinc sulfate is a common pesticide mainly used for preventing and treating zinc deficiency in soil and plants. The following is the usage method of agricultural zinc sulfate:

1. Determine the zinc content of soil and plants: Before using zinc sulfate, it is recommended to conduct zinc content tests on soil and plants. This can be done through a professional laboratory to determine whether zinc sulfate needs to be added.

2. Determine the application dose: Determine the application dose of zinc sulfate based on the zinc content of soil and plants. Generally speaking, the dosage of zinc sulfate applied per acre in soil is 2-5 kilograms, and the dosage of zinc sulfate applied per acre in plants is 300-500 grams.

3. Application time and method: The optimal application time for zinc sulfate is during critical periods of crop growth, such as planting, flowering, and fruiting. Zinc sulfate can be applied by root application, leaf spray or seed treatment.

-Root application: Dissolve zinc sulfate in an appropriate amount of water and evenly irrigate the soil around the plant roots.
-Leaf spray: Dissolve zinc sulfate in water, and use a spray to evenly spray on the leaves of plants.
-Seed treatment: Dissolve zinc sulfate in an appropriate amount of water, soak the seeds in the solution, and air dry before planting.

4. Precautions for application: When using zinc sulfate, the following points should be noted:
-Do not apply excessive amounts of zinc sulfate to prevent damage to plants.
-When applying zinc sulfate, it is necessary to evenly cover the entire field or plant body.
-Avoid mixing with other fertilizers or pesticides to prevent adverse reactions.
-When using zinc sulfate, wear protective equipment to avoid direct contact with skin and eyes.

5. Pay attention to safe use: Zinc sulfate is a toxic substance. When using it, follow the relevant safety procedures and store it out of reach of children. If accidental ingestion or contact occurs during use, seek medical attention immediately.
