How do we choose the right water-soluble fertilizer?


In recent years, water-soluble fertilizers with a large number of elements have been recognized by more and more people. Due to the characteristics of low dosage, high absorption and utilization, quick effect and not easy to cause fertilizer residue, fruit farmers or vegetable farmers are more and more recognized. However, with the development of the market, there are more and more kinds. How can we choose the appropriate water-soluble fertilizer when we choose? Today, let's briefly talk about:
At present, common water-soluble fertilizers include powder water-soluble fertilizer and liquid water-soluble fertilizer. There are many water-soluble fertilizers in powder. Generally, it is better to use potassium nitrate and potassium dihydrogen phosphate as raw materials, and it is better to be rich in * * trace elements.
Liquid water-soluble fertilizers generally have clear liquid type, that is, they only contain elements in nitrogen, phosphorus and potassium, with trace elements containing * *. The other is suspension type, which contains not only nitrogen, phosphorus and potassium, but also organic matter, humic acid, amino acid and other nutrients required by plants.
For these two kinds of water-soluble fertilizers, although the absorption and utilization effect of clear liquid type is good, due to its high cost, it is suitable for foliar spraying. At present, many people are easily confused with the water-soluble fertilizer containing humic acid. The content of nitrogen, phosphorus and potassium in the water-soluble fertilizer containing humic acid is generally lower than 200g / L. it does not belong to the water-soluble fertilizer of large elements and generally can not meet the supplement of nitrogen, phosphorus and potassium by plants, Therefore, you need to pay attention when choosing.
For the liquid suspension water-soluble fertilizer, the soil will be much better after long-term use because it can make the soil plants supplement nitrogen, phosphorus and potassium as well as * * organic matter and a variety of trace elements.
Generally, this kind of fertilizer belongs to the water-soluble fertilizer of rooting sample plot, so we can find the water-soluble fertilizer of rooting sample plot containing organic humic acid when selecting. We should pay attention to the overall content * * of nitrogen, phosphorus and potassium should be 200g / L.
At present, we should not only consider the effect of planting, but also consider whether the quality of the fruits we plant after use is good. Only the quality and taste are improved. If the yield is good, our planting efficiency will not be very low. At least, the sales should not worry a lot. Therefore, for the choice of water-soluble fertilizer, we can try the water-soluble fertilizer that nourishes the land and replenishes fertilizer.
