Several considerations for increasing the fertilizer efficiency of micro-fertilizers

In order to effectively enhance the fertilizer efficiency of trace element fertilizers, the following problems should be noted when applying:

First, the response of crops to trace element nutrients.

Various types of crops have different responses to different types of trace element nutrients. In general, the corresponding micro-fertilizer should be selected for use on crops with higher sensitivity. For example, general rapeseed is more sensitive to boron, and the effect of applying shed fertilizer is also very good.

Second, the ability of the soil to supply trace element nutrients.

Whether the soil lacks certain trace elements is related to the parent material and the process of soil formation, and the effectiveness of trace elements is affected by many conditions, especially the pH value is most significant. For example, soil alkalinity will reduce the effectiveness of elements such as iron, boron, manganese, copper, and zinc, but the effectiveness of steel has increased. On acidic soils, the acidity of the soil increases the effectiveness of iron, manganese, copper and zinc, while the effectiveness of steel is very low. Therefore, it should be targeted when applying micro-fertilizer.

Third, with a large amount of elemental fertilizer application.

In the process of agricultural production, the demand for large amounts of nutrients in crops is very large, and the soil is often lacking, and needs to be replenished in time. Micronutrient elements will only be very good if they meet the demand for large amounts of nutrients. Fertilizer effect. Therefore, micro-fertilizer should be applied together with NPK fertilizer.
