8 recipes for making your own water-soluble fertilizer

In agricultural production, water-soluble fertilizers are used more and more frequently. Many farmers can make their own water-soluble fertilizers. The formula needs to be adjusted according to the different needs of crops and growth stages. Water-soluble fertilizers need to be diluted before use to avoid direct use of high-concentration fertilizers that may cause damage to crops. Below, the editor will introduce 8 recipes for homemade water-soluble fertilizers. Let’s take a look.

1. 8 recipes for homemade water-soluble fertilizers

1. General water-soluble fertilizer

General water-soluble fertilizer is suitable for the general growth stage of most crops, including 1 part urea (46% N), 1 part potassium dihydrogen phosphate (86% P2O5, 34% K2O), and 100 parts water.

2. High nitrogen water-soluble fertilizer

High-nitrogen water-soluble fertilizer is suitable for leafy crops, consisting of 3 parts of urea (46% N), 1 part of potassium dihydrogen phosphate (86% P2O5, 34% K2O), and 100 parts of water.

3. High phosphorus water-soluble fertilizer

High-phosphorus water-soluble fertilizer is suitable for use before flowering and fruiting, including 2 parts of superphosphate (20% P2O5), 1 part of urea (46% N), 1 part of potassium sulfate (50% K2O), and 100 parts of water.

4. High potassium water-soluble fertilizer

High-potassium water-soluble fertilizer is suitable for the fruit expansion period, 3 parts of potassium sulfate (50% K2O), 1 part of urea (46% N), 1 part of potassium dihydrogen phosphate (86% P2O5, 34% K2O), and 100 parts of water.

5. Calcium fertilizer type water-soluble fertilizer

Calcium fertilizer type water-soluble fertilizer is suitable for calcium-deficient crops, including 2 parts of calcium nitrate (15.5% N, 17% CaO), 1 part of urea (46% N), 1 part of potassium dihydrogen phosphate (86% P2O5, 34% K2O), and 100 parts of water.

6. Trace element water-soluble fertilizer

Trace element water-soluble fertilizer is suitable for supplementing trace elements, including 0.05 parts of zinc sulfate (ZnSO4·H2O), 0.05 parts of manganese sulfate (MnSO4·H2O), 0.05 parts of boric acid (H3BO3), 0.01 parts of ammonium molybdate ((NH4)6Mo7O24·4H2O), 1 part of urea (46%N), and 100 parts of water.

7. Organic acid water-soluble fertilizer

Organic acid type water-soluble fertilizer is suitable for improving soil pH, 0.5 parts of citric acid (C6H8O7), 1 part of urea (46%N), 1 part of potassium dihydrogen phosphate (86%P2O5, 34%K2O), and 100 parts of water.

8. Amino acid water-soluble fertilizer

Amino acid type water-soluble fertilizer is suitable for improving crop resistance to stress. It consists of 2 parts of amino acid water-soluble fertilizer (containing multiple amino acids), 1 part of urea (46% N), 1 part of potassium dihydrogen phosphate (86% P2O5, 34% K2O), and 100 parts of water.

2. Precautions

1. The formula ratio of the above homemade water-soluble fertilizer is approximate, and the specific dosage should be adjusted according to crop needs and soil conditions.

2. When making your own water-soluble fertilizer, make sure all the raw materials are soluble and mixed evenly. Small-scale tests should be conducted before use to ensure the safety and effectiveness of the fertilizer.

3. Water-soluble fertilizers have high nutritional content. The amount of fertilizer should be controlled when applying. Apply small amounts frequently. Generally, 3-6 kg is applied per mu of land.

4. Avoid mixing with strong alkaline substances to prevent reducing fertilizer efficiency or causing precipitation. When storing, avoid direct sunlight and high temperatures to prevent the fertilizer from decomposing.

The above are 8 recipes for homemade water-soluble fertilizers. When making your own water-soluble fertilizers, you must ensure the purity and quality of the raw fertilizers, and adjust the formula according to the specific needs and growth stages of the crops. At the same time, the correct preparation methods and usage precautions should be followed to ensure the fertilizer efficiency and healthy growth of crops.
