How To Avoid Chemical Fertilizer Restrain Each Other?
I think,most people probably haven’t thought about this question. We just want to post our review on chemical fertilizer.
Usually, we say chemical fertilizer restrains each other, in fact, that is elments in chemical fertilizer restrain each other. As we mentioned earlier, the combination of fertilizers can improve soil fertility more effectively.But today we’re going to remind you that
although fertilizer can be mixed scientifically, but we should also be careful not to mix blindly, this may have adverse consequences.
This is called “RESTRAIN”.
If phosphate fertilizer is applied, the surplus available p can be combined with available zinc in soil to form insoluble zinc phosphate precipitation, which leads to the deficiency of available zinc in soil.moreover, but the excess available phosphorus also inhibits nitrogen uptake by crops, causing nitrogen deficiency.
When potash is applied more, excess potassium reduces the absorption of nitrogen, magnesium, calcium, boron, and zinc in crops, causing a lack of these nutrients in crops.
So how to prevent elements from restraining? You may take measurements as below:
A: Balanced fertilization as much as possible
Excessive application of simple fertilizers to crops not only wastes fertilizer and increases production costs, but also leads to the shortage of some other nutrients or other elements. When fertilizing, according to the different structure of crop fertilizer needs and the ability of soil to feed, achieve the amount of input, balance nutrients.
B: Alternate application period or body part
If zinc fertilizer and phosphate fertilizer mixed, that can certainly lead ” restrain”.Therefore, phosphate fertilizer should be applied as base fertilizer and zinc fertilizer should be applied as top fertilizer. Large amount of element fertilizer such as nitrogen, phosphorus and potassium should be based on rhizospheric fertilizer, and micro fertilizer should be sprayed by leaf surface.
C: Appropriate proportion relationship
Relative to simple fertilizer, the proportion of nutrients in compound fertilizer or compound&blended fertilizer is more appropriate and harmonious.Therefore, fertilizering should be given priority to with compound fertilizer, with elemental fertilizer as auxiliary.
D: Tighten up the scope of contact
The method of spraying nitrogen and potash fertilizer can be adopted.The method of concentrated fertilization can be adopted for phosphate fertilizer;Micro fertilizers can be divided into seed dressing, seed soaking and root dipping, so that trace elements can be confined within a small range of the root and not contact with a large number of elements.
