What are the precautions for applying trace element fertilizers?
When we plant, fertilizing is indispensable, and since crops have relatively comprehensive nutritional needs, fertilizers are divided into inorganic fertilizers, organic fertilizers and trace element fertilizers, etc. Among them, crops need relatively little trace element fertilizer, but its importance is no less than that of macronutrients. When a certain trace element is lacking, it will seriously affect the growth of crops, so what precautions should we take when applying trace elements? Let's take a look together below!
1. Pay attention to the dosage
As just mentioned, although most crop growth cannot do without trace elements, the demand for trace elements is very low. There are many types of trace elements, and the range for crops from deficiency to satisfaction for many trace elements is very small. So when applying trace elements, we must pay attention to controlling the dosage well. Be sure to apply them thoroughly and evenly to prevent excessive application, which leads to overly high concentration and instead affects crop growth.
2. Apply according to the corresponding deficiency
When planting, soils of different properties and types will contain different trace elements, and the effect of applying trace elements will also differ accordingly. For example, in most northern regions, the content of trace elements such as zinc, manganese and boron in the soil is relatively low, and their availability is also insufficient. In southern soils, molybdenum deficiency is prone to occur. So when applying trace elements, we must control the types of trace elements well according to the trace element situation of the soil, following the principle of applying whatever is lacking.
3. Crop type
When applying trace elements, we should also pay attention to what crop is being planted. Because different crops respond to and adapt to various trace elements differently, their demand for trace elements will also have different requirements. For example, when planting corn, attention should be paid to increasing the proportion of zinc fertilizer, while rapeseed has a relatively high demand for boron. Therefore, when applying trace elements, we should pay attention to controlling the use of different trace elements according to the planted crop.
4. Improving the soil
When crops show deficiency symptoms during growth, it is generally caused by insufficient trace elements in the soil and poor soil quality. Soil pH is the primary reason affecting the content of trace elements in the soil, followed by properties, moisture, permeability, etc. So in order to solve the problem of insufficient trace elements, when applying trace element fertilizers, we should also pay attention to doing a good job in soil improvement. If the soil is too acidic, increase the application of organic fertilizer; on the contrary, it is necessary to sprinkle quicklime powder to improve the soil structure.
5. Combine with fertilization
When planting, only after the crop's demand for macronutrients such as nitrogen, phosphorus and potassium is satisfied can trace element fertilizers be effective. Organic fertilizer contains relatively many trace elements and is also an important measure for supplementing soil trace elements. Properly applying organic fertilizer can improve soil quality, thereby increasing the trace element content of the soil. The combined application of organic fertilizer and trace element fertilizer is the key to ensuring that the crop's nutritional needs are met.
The above is a brief introduction to the precautions for applying trace element fertilizers. Trace element fertilizers play a very critical role in crop growth. They cannot be ignored when we plant, and everyone must pay close attention to them. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
