What precautions should be taken when using fertilizers?

1. Fertilizers should be prepared and used immediately

The fertilizer must be prepared and used immediately, especially in the case of poor water quality, to prevent the fertilizer components from reacting with the substances in the water.

2. Choose the right fertilization time

In the case of sunny days with high temperature, fertilization should be selected before ten o'clock in the morning and after four o'clock in the afternoon, avoid fertilizing under strong sunlight; avoid fertilizing in rainy days, especially foliar spraying, to avoid fertilizer loss.

3. When applying water-soluble fertilizer through drip irrigation, drip water first

When applying water-soluble fertilizer through drip irrigation, use clear water first. Start fertilizing when the pipes are full of water. Immediately after fertilization, drip water for 20 to 30 minutes to discharge all the residual fertilizer in the pipeline. If the tube is not cleaned, moss, algae, etc. or microorganisms may grow on the dripper, blocking the dripper.

4. Pay attention to the pH and whether flocculation occurs when mixing with pesticides

When mixing with pesticides for root irrigation or foliar spraying, it is necessary to avoid the mixing of acidic fertilizers and alkaline pesticides, and the mixing of alkaline fertilizers and acidic pesticides. At the same time, pay attention to whether there is flocculation during mixing. If flocculation occurs, mixing is prohibited.
