Common misunderstandings about Fertilizer

Fertilizer is one of the indispensable means of production in agricultural production. Farmers' understanding of fertilizer has been increasing in recent years, but there are still many misunderstandings in fertilizer understanding.

The low yield is due to fertilizer.

A small number of users think that the failure to increase the output is the reason for the fertilizer. In fact, there are many reasons for the increase in the yield, such as weather, soil quality, fertilization methods, selection of fertilizer products, seeds, pesticides and field management, etc., which should be examined from various aspects. fertilizer is only one of the factors.

The same formula, the same dosage, the same effect.

The reason is very simple, the main difference between fat people and thin people is not the problem of eating more or less, but the problem of absorbing more and less. Fertilizer is the same, the same formula the same amount due to the product itself, there will be a significant difference in nutrient utilization, which is why we now vigorously promote scientific formula fertilization technology.

After using the fertilizer containing nitrogen, phosphorus and potassium, other fertilizers will not be used.

Some farmers think that there is no need to apply other fertilizers after applying ammonium bicarbonate, phosphate and potash, which is wrong, while some farmers think that they do not need to use other fertilizers after using compound fertilizers, which is also wrong. Simple fertilizers or compound fertilizers generally contain only nitrogen, phosphorus and potassium. If we do not pay attention to the timely supplement of effective medium and micronutrient elements, it will also have an impact on crop yield. For example, long-term non-application of boron fertilizer on cotton will affect its flowering and lead to a decline in yield; the bottom of new leaves of rice will lose green and fade, the whole plant is short without tillering, and the field grows unevenly, which may also be a symptom of zinc deficiency, not necessarily caused by disease.
