Water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water. The absorption and utilization rate of crops is 2 to 3 times that of ordinary chemical fertilizers. It improves fertilizer utilization, saves agricultural water, reduces environmental pollution, and improves Crop quality and labor reduction play an important role. At present, general consumption areas are mainly concentrated in greenhouse vegetable production bases, fruit tree production bases and some flower planting areas.

Look at the nutrient content of each element on the packaging bag

According to the standards of macroelement water-soluble fertilizers, the single nutrient content of the three elements of nitrogen, phosphorus and potassium cannot be less than 4%, and the sum of the three elements cannot be less than 50%.

The content of trace elements refers to the sum of the content of copper, iron, manganese, zinc, boron, and molybdenum. The product should contain at least one trace element. The total content of trace elements cannot be less than 0.2%

Large element + medium element type:

The content of medium elements refers to the sum of calcium and magnesium. The product should contain at least one medium element, and the total content of medium elements cannot be less than 1.0%

The particles of good quality water-soluble fertilizer products are uniform and crystalline (the particle size is similar to that of table salt).

Water-soluble fertilizers are quick-acting fertilizers and generally can only be used as top dressing. Especially in conventional agricultural production, water-soluble fertilizer cannot replace other conventional fertilizers. It is necessary to combine base fertilizer with top dressing, organic fertilizer with inorganic fertilizer, and water-soluble fertilizer with conventional fertilizer in order to reduce costs and give full play to the advantages of various fertilizers.
