water soluble fertilizer with a large number of elements is a commonly used fertilizer in agricultural production in recent years. It has good water solubility, no residue, is easy to be absorbed and can be completely dissolved in water. Today, let's learn about the effect of applying a large number of elements water soluble fertilizer for a few days and the matters needing attention in its use!

As the fertilizer effect of water soluble fertilizer is related to the formula raw materials and production and manufacturing process, the following

will answer the question of the application effect of general and high-end water soluble fertilizer.

1, general water-soluble fertilizer, general water-soluble fertilizer because the raw material composition is relatively single, such as only containing 1. two kinds of fertilizer, fertilizer effect retention period is only about 10 days, water-soluble aspects of the existence of insoluble substances, it directly leads to the decline of fertilizer effect, shorten the duration of effect, generally within one week after dissolution and scouring can be effective.

2, high-end water-soluble fertilizer, relatively high-end water-soluble fertilizer is produced and processed, soluble in water, and the fertilizer is valid for about 20 days. It is usually effective 5-7 days after the action of the granule.

introduces the matters needing attention in the application of water soluble fertilizer with a large number of elements:

, avoid direct application.

suggests not to apply compound fertilizer directly according to the method of applying compound fertilizer, but to adopt the "secondary dilution" method.

At present, some farmers directly apply water-soluble fertilizer to vegetables according to the common compound fertilizer application method, resulting in uneven fertilizer application, root injury and yellow leaves of vegetables with large amount of fertilizer application, and the growth of vegetables with small amount of fertilizer application is affected. The secondary dilution method is not only beneficial to the uniformity of fertilization, but also can improve the utilization rate of fertilizer. Water soluble fertilizer than ordinary compound fertilizer nutrient content is high, the amount of less, 8-10kg can reach one mu.

2. Hole application.

Cave water soluble fertilizer should pay attention to the amount of application.

Cave application of chemical fertilizer has the characteristics of centralized fertilization, high utilization rate and low fertilization amount. At present, many farmers are not sure about the amount of water-soluble fertilizer applied in holes, resulting in the burning of roots and seedlings.

remind, hole water soluble fertilizer must pay attention to the amount of application, and to be fully mixed with the soil before planting.

3. Spraying.

When spraying water-soluble fertilizer, it should be used as single as possible or mixed with non-alkaline pesticides.

When vegetable crops have a deficiency or poor root system development, many farmers choose to spray water-soluble fertilizers to relieve symptoms.

Water soluble fertilizer manufacturer

recommends that farmers should spray it alone as much as possible or mix it with non-alkaline pesticides to avoid metal ions reacting and precipitating, causing leaf fertilizer or pesticide damage.
