Misunderstanding 1:
The more expensive the price, the better. Many farmers think that the more expensive the phosphate fertilizer, the better the quality, but it is not. Some unscrupulous traders deliberately raise the price of low-cost phosphate fertilizers, and then transmit the wrong concept of “high quality and good quality†to guide farmers to purchase. Faced with this phenomenon, farmers need to look at it rationally. When purchasing, first of all, whether the phosphate fertilizer has sour taste, whether the color is grayish white, and then whether it feels cool when touched by hand, finally confirm whether the packaging information is complete, in line with the above conditions, is the high quality phosphate fertilizer.
Misunderstanding 2:
The more the foaming, the better. Some experts said that most of the phosphate fertilizer is because the free acid content of calcium phosphate exceeds the standard. It is not the more foaming that the farmers think, the better the effect. After application, the phosphate fertilizer with more foaming will inhibit the activity of microorganisms in the soil, burn out the roots of the crops, and cause the seeds to not germinate. The standard for good phosphate fertilizer is that the free acid content of calcium phosphate is not more than 5.5%.
Misunderstanding three:
Applying too much phosphate fertilizer to the application of excessive phosphate fertilizer will destroy the nutritional balance of the crop, making the plant respiration too strong, causing poor growth and development of the plant, which in turn leads to a decline in crop yield. Therefore, farmers need to apply proper fertilizer according to the crop area, so that the fertilization effect will be good.
Misunderstanding 4:
The organic fertilizer and the phosphate fertilizer are rich in phosphorus, and then the same as the phosphate fertilizer, but will reduce the effect of the phosphate fertilizer, which is not worth the candle. It is recommended that farmers apply the two fertilizers separately, first apply organic fertilizer, and then apply phosphate fertilizer every 3 to 5 days, so that the fertilization effect is obvious and the crop grows faster.
