Phosphorus fertilizer is one of the three essential nutrients for crop growth. It can promote the crop yield and improve the quality of crops. It is widely loved by farmers. Although the benefits of phosphate fertilizers are numerous, they also need to be properly selected in order to maximize their effectiveness. The following are common mistakes in the use of phosphate fertilizers:
Misunderstanding 1:
The more expensive the better
Many farmers believe that the more expensive the price of phosphate fertilizer, the better the quality, but it is not. Some unscrupulous traders deliberately raised the price of low-priced phosphate fertilizer, and then transmitted the erroneous concept of “high price and good quality†to guide farmers to purchase. In the face of this phenomenon, farmers need to be rational. When purchasing, first of all, do you smell whether the phosphate fertilizer is sour and whether the color is gray and then you can feel cool when you touch it with your hands. Finally, confirm whether the packaging information is complete and meet the above conditions. It is a good quality phosphate fertilizer.
Misunderstanding 2:
The more bubbles, the better. Some experts have stated that most of the phosphate fertilizer is out of foam because the calcium phosphate free acid content exceeds the standard, and it is not the farmers who think that the more bubbles, the better the efficacy. After the application of more phosphate fertilizer, it will inhibit the activity of microorganisms in the soil, burn the roots of the crops, and cause the seeds not to germinate. The standard for good phosphate fertilizer is that the content of calcium phosphate free acid is not more than 5.5%.
Misunderstanding three:
Phosphate fertilizer is more than good
Excessive application of P fertilizer will destroy the nutritional balance of the crop, make the plant respiration too strong, cause plant growth and development, and lead to a decline in crop yield. Therefore, farmers need to apply fertilizer in a reasonable amount according to crop area, so that the effect of fertilization will be good.
Misunderstanding 4:
Organic fertilizer and phosphate fertilizer applied together
Organic fertilizer itself is rich in phosphorus, and then with the application of phosphate fertilizer, but will reduce the effect of phosphate fertilizer, not worth the candle. Farmers are advised to separate the two fertilizers, apply organic fertilizer first, apply phosphate fertilizer every 3-5 days, so that the effect of fertilization is obvious, and the crop grows faster.
