The most complete water-soluble fertilizer formula ratio

Water-soluble fertilizer is a highly efficient and easily absorbed fertilizer . It is dissolved in water and supplied to crops through foliar spraying, drip irrigation, etc. It can be quickly absorbed and utilized by the crop roots or leaves. Below, the editor will introduce the most complete formula ratio of water-soluble fertilizer, let’s take a look.

1. Balanced water-soluble fertilizer formula

① 6 kg of urea, 4 kg of potassium dihydrogen phosphate, 4 kg of diammonium phosphate, and 6 kg of potassium nitrate. After mixing, the content is: nitrogen 21.3%, phosphorus 19.6%, and potassium 20.6%.

② 8 kg of urea, 8 kg of potassium dihydrogen phosphate, and 4 kg of potassium nitrate. After mixing, the content is: nitrogen 21.0%, phosphorus 20.8%, and potassium 22.8%.

③ 3 kg of urea, 8.5 kg of diammonium phosphate, 8.5 kg of potassium nitrate, after mixing: nitrogen 20.1%, phosphorus 19.6%, potassium 19.6%.

④ 5 kg of urea, 7.5 kg of diammonium phosphate, 7.5 kg of potassium sulfate, after mixing: nitrogen 18.3%, phosphorus 17.3%, potassium 18.8%.

⑤ 9 kg of urea, 3 kg of potassium sulfate, and 8 kg of potassium dihydrogen phosphate. After mixing, the content is: 20.7% nitrogen, 20.8% phosphorus, and 21.1% potassium.

2. High potassium water-soluble fertilizer formula

① 5 kg of urea, 13 kg of potassium sulfate, and 2 kg of potassium dihydrogen phosphate. After mixing, the content is: nitrogen 11.5%, phosphorus 5.2%, and potassium 35.9%.

② 2 kg of urea, 15 kg of potassium nitrate, and 3 kg of potassium dihydrogen phosphate. After mixing, the content is: 14.4% nitrogen, 7.8% phosphorus, and 39.6% potassium.

③ 3 kg of urea, 2 kg of diammonium phosphate, and 15 kg of potassium sulfate. After mixing, the content is: nitrogen 8.7%, phosphorus 4.6%, and potassium 37.5%.

④ 16 kg of potassium nitrate and 4 kg of potassium dihydrogen phosphate, after mixing: nitrogen 10.4%, phosphorus 10.4%, potassium 43.6%.

⑤ 3 kg of diammonium nitrate and 17 kg of potassium nitrate, after mixing: nitrogen 13.8%, phosphorus 4.9%, potassium 39.1%.

3. Other formulas

The formula with a nitrogen, phosphorus and potassium ratio of 1:1:1 is suitable for the growth needs of most crops. At the same time, a variety of medium and trace elements are added to help improve the crop's resistance and quality. The formula ratio is 20% total nitrogen, 3.4% nitrate nitrogen, 1.4% ammonium nitrogen, 15.2% urea nitrogen, 20% water-soluble phosphorus, 20% soluble potassium, and appropriate amounts of trace elements (such as iron, manganese, zinc, copper, boron, molybdenum, magnesium, etc.).

The above is the most complete formula ratio of water-soluble fertilizer. The application of water-soluble fertilizer should follow the principle of small amounts and multiple times. Generally, the amount used per mu each time is 3-6 kilograms. At the same time, pay attention to nutrient balance, avoid excessive irrigation, and try to apply it alone or mixed with non-alkaline pesticides to avoid precipitation and fertilizer or drug damage to the leaves.
