Formula and preparation method of water-soluble fertilizer

Water-soluble fertilizer is a kind of fertilizer that must be used in the process of crop planting. Now many farmers can make their own water-soluble fertilizer. When making water-soluble fertilizers, make sure that the water-soluble fertilizers are completely dissolved in water to avoid precipitation or crystallization that affects the fertilization effect. Below, I will introduce the formula and production method of water-soluble fertilizer. Let’s take a look.

1. Formula of water-soluble fertilizer

1. Formula of macronutrient water-soluble fertilizer

The formula mainly includes macroelements such as nitrogen, phosphorus, potassium, etc., and also adds some medium and trace elements such as calcium, magnesium, sulfur, iron, manganese, copper, zinc, molybdenum, etc. The fertilizer effect of this formula is relatively comprehensive and can meet the various nutrients required for plant growth.

2. Potassium dihydrogen phosphate formula

The formula mainly includes raw materials such as potassium dihydrogen phosphate and urea, and appropriate amounts of trace elements such as boron, zinc, iron, manganese, etc. are added. The fertilizer effect of this formula is quite outstanding, especially in promoting the flowering and fruiting of plants.

3. Amino acid water-soluble fertilizer formula

The formula mainly uses amino acids as raw materials, adds appropriate amounts of nitrogen, phosphorus, potassium and other elements, and can also add some trace elements such as iron, manganese, copper, zinc, etc. This formula has a relatively mild fertilizer effect and can promote cell division and tissue formation in plants.

4. Humic acid water-soluble fertilizer formula

The formula mainly uses humic acid as the raw material, adds appropriate amounts of nitrogen, phosphorus, potassium and other elements, and can also add some trace elements such as iron, manganese, copper, zinc, etc. These formulas are formulated according to the growth needs and nutrient requirements of different plants to achieve better fertilization effects.

2. How to make water-soluble fertilizer

1. Raw material preparation: Select high-quality raw materials, including nitrogen sources (such as urea), phosphorus sources (such as potassium dihydrogen phosphate), and potassium sources (such as potassium nitrate or potassium sulfate).

2. Weighing: Accurately weigh various raw materials according to the formula ratio.

3. Mixing: Mix the weighed raw materials evenly. If there is no professional mixing equipment, you can dissolve the raw materials in water first and then mix them.

4. Dissolution: Add the mixed raw materials into water and stir thoroughly until completely dissolved.

5. Storage: Store the prepared water-soluble fertilizer solution in a suitable container, away from light and high temperature.

The above is the formula and production method of water-soluble fertilizer. When making water-soluble fertilizer, we must follow the principle of "small amounts and multiple times" to avoid excessive fertilization that may cause root burn or waste.
