How to use water-soluble fertilizer effectively?

Water-soluble fertilizer , as an efficient and convenient form of fertilizer , has been widely used in modern agricultural production. However, in order to truly maximize its effectiveness, it is very important to master the correct method of use. So how to use water-soluble fertilizer effectively? Let’s learn more about it below.

1. Scope of application

Water-soluble fertilizer is a highly efficient form of fertilizer that can be completely dissolved in water, making it easy for crops to absorb through their roots and leaves. Its application range is very wide, covering almost all crops and scenarios that require fertilization, and is especially suitable for the following situations:

(1) Facility agriculture, such as greenhouses and canopies .

(2) Drought or water-scarce areas.

(3) High-value cash crops .

2. Usage time

It is generally recommended to apply water-soluble fertilizers in the evening or on sunny mornings, and avoid applying fertilizers during high temperature periods to prevent rapid evaporation of the fertilizer and reduce its utilization rate. At the same time, avoid fertilizing on rainy days, especially foliar spraying, to prevent fertilizer loss.

3. Usage

(1) Fertilization: Fertilizer solution is evenly applied to the soil through drip irrigation or sprinkler irrigation system.

(2) Foliar spraying: Spray the diluted fertilizer solution on the crop leaves, both front and back.

(3) Soil irrigation: Mix water-soluble fertilizer with water during irrigation so that the plant roots are fully exposed to the fertilizer.

4. Fertilization frequency

The frequency of fertilization should be determined based on the growth rate of the crop and the type of fertilizer. Generally speaking, fertilizer should be applied every 15 days or so. However, for crops that grow faster or require more fertilizer, the frequency of fertilization can be appropriately increased.

5. Notes

(1) Control the amount of fertilizer: Avoid excessive fertilization. Generally, 3-6 kg per mu of land should be applied.

(2) Fertilizer concentration: Read the instructions carefully before use and dissolve and use according to the recommended ratio. To avoid excessive fertilizer concentration.

(3) Safety interval: There should be a certain interval after fertilization to avoid frequent fertilization.

(4) Prepare fertilizers for immediate use: Fertilizers must be prepared and used immediately, especially when the water quality is poor, to prevent the fertilizer components from reacting with substances in the water.

(5) Avoid direct fertilizer application: Use the "secondary dilution" fertilizer application method to ensure uniform fertilizer application.

In general, if you want to use water-soluble fertilizers well, you must pay attention to every small detail such as time, concentration, frequency, etc. And mastering the correct usage and dosage will help improve crop yield and quality.
