Large elements of water-soluble fertilizer is a nutrient that can be completely dissolved in water ******, fast-acting water-soluble fertilizers, not only can be used for irrigation fertilizer, foliar fertilizer can also be used for soilless cultivation and so on. So what is considered a good water soluble fertilizer?
A good bag of water-soluble fertilizer should have the following characteristics:
First, the element content ******, sufficient, the fertilizer should also have large elements of nitrogen, phosphorus, potassium, and medium elements of calcium, magnesium, sulfur, in addition to containing some of the
Necessary trace elements boron, manganese, iron and so on. Which the total content of large elements can not be less than 50%, the content of a single element ****** can not be less than 6%.
Second, rich in macromolecules of organic activation factors must be rich in soil and crops need organic activation factors, these activation factors include: carboxyl, hydroxyl, phenolic hydroxyl, quinone, methoxy, etc., because only these can improve the soil, improve the soil's ability to retain fertilizer, water retention, so that the soil's resistance to adversity greatly enhanced.
Third, the ability ****** to use fertilizers can not contain any ****** substances, chlorine elements, and fertilizers do not contain components that pollute the environment and damage the soil.
Fourth, with the phosphorus element does not occur antagonistic reaction which requires the fertilizer to join the water-soluble chelated state trace element compositions, because this can ensure that the phosphorus element does not occur antagonistic reaction.
Only a good large number of elements of water-soluble fertilizer can play a significant increase in yield, improve the purpose of the soil.
