What is the difference between water-soluble flush fertilizer and compound fertilizer? Please explain
Water-soluble flush fertilizer, also called water-flush fertilizer, is a fertilization method in which solid quick-acting chemical fertilizer is dissolved in water and applied with the water. From the perspective of fertilizer use, crops absorb nutrients mainly through their roots, and the root hair zone about 1 cm from the root tip is the most active area for nutrient absorption. Therefore, water-soluble flush fertilizer best matches the principles of scientific fertilization: nutrients can be absorbed by crops through mass flow and diffusion, and it can also prevent seedling burn caused by dry broadcasting of fertilizer. From the perspective of the fertilization method, water-soluble flush fertilizer both fertilizes the crop and waters it, which in practice is the application of integrated water and fertilizer technology.
So, with the development and promotion of fertilization technology, can water-soluble flush fertilizer completely replace compound fertilizer? According to relevant experts, traditional compound fertilizer is generally used as a base fertilizer and in large amounts. As a result, crops may suffer from excessive nutrients in the early stage and insufficient nutrients in the later stage, which is not conducive to crop growth, so this fertilization method is actually unscientific. Although applying topdressing in small amounts multiple times is the best way to supplement nutrients to crops, the main problem at present is that labor costs are too high; it may be usable for cash crops or greenhouses, but it is not very practical for field cultivation. The development of drip irrigation fertilization technology can make this method achievable, and some even say that if sufficient topdressing can be guaranteed, there is no need to apply base fertilizer to crops, and the manufacturing process of water-soluble flush fertilizer is simpler and lower in cost than that of compound fertilizer.
At present, water-soluble flush fertilizer is widely used on greenhouse and open-field vegetables, mainly during the vigorous growth period of vegetables, for example the full fruit stage of fruit vegetables, after each harvest of melons and fruits, and the heading stage of Chinese cabbage, etc., with quick results and good effects.
However, with the development of slow and controlled release fertilizer technology, the utilization rate of compound fertilizer has been greatly improved, and nutrients can also be released evenly throughout the entire crop growth period. Although it cannot be said now that water-soluble flush fertilizer can completely replace compound fertilizer, water-soluble flush fertilizer products have gradually become a hot term among dealers and farmers, and a large number of domestic water-soluble flush fertilizer companies are gradually establishing their own brands, so water-soluble flush fertilizer will enter a new stage of development.
