Large element water-soluble fertilizer super potassium type

Water-soluble fertilizer refers to a compound fertilizer containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc. that can be completely dissolved in water. There are solid water-soluble fertilizers and liquid water-soluble fertilizers. According to the nutrient content, it is divided into large-element water-soluble fertilizers, medium-element water-soluble fertilizers, trace-element water-soluble fertilizers, amino acid-containing water-soluble fertilizers, humic acid-containing water-soluble fertilizers, organic water-soluble fertilizers, etc.

Water-soluble fertilizers have obvious advantages over traditional superphosphate fertilizers and other varieties. It is a fast-acting fertilizer with good water solubility and no residue. It is completely soluble in water and can be directly absorbed and utilized by the roots and leaves of crops.

As a kind of fast fertilizer, water-soluble fertilizer has relatively comprehensive nutritional elements. According to the fertilizer characteristics of different crops, the corresponding fertilizer formulas are different. Special water-soluble fertilizers for vegetables, fruit trees, flowers, food, cotton, oil and other crops are sold on the market.

skills:

1. Avoid direct flushing and use secondary dilution method. Because water-soluble fertilizers are different from general compound fertilizers, farmers cannot apply them according to conventional fertilization methods, resulting in uneven fertilization, burning of seedlings, root damage, weak seedlings, etc. Secondary dilution ensures uniform fertilization and improves fertilizer utilization. Rate.

2. Strictly control the amount of fertilizer applied. Water-soluble fertilizers have higher nutrient content than general compound fertilizers, and their dosage is relatively small. Because of its strong quick-acting effect, it is difficult to persist in the soil for a long time. Therefore, the amount of fertilizer must be strictly controlled to avoid fertilizer loss, which will reduce the economic benefits of fertilization and fail to achieve the goal of high yield, high quality and high efficiency.

3． Try to use it alone or mix it with non-alkaline pesticides. For example, when vegetables suffer from nutrient deficiencies or poor root growth, many farmers use the method of spraying water-soluble fertilizers to alleviate the problem. We would like to remind farmers that water-soluble fertilizers should be applied alone or mixed with non-alkaline pesticides to avoid metal ions reacting and precipitating, causing leaf fertilizer damage or phytotoxicity damage.
