What is the relationship between water-soluble fertilizer and foliar fertilizer
In fact, water-soluble fertilizer is a very large range. Any fertilizer that can dissolve in water can be called water-soluble fertilizer; foliar fertilizer is sprayed through the leaves of crops and absorbed the same, so it naturally belongs to water-soluble fertilizer. Water-soluble fertilizer is a fast fertilizer among fertilizers, and foliar fertilizer is a fast fertilizer among water-soluble fertilizers.
How to judge the difference between the two
Water-soluble fertilizer:
A high-quality fertilizer with relatively high content and purity, and more nutrient types. It has good water solubility and will not produce precipitation, and can be used by diluting larger multiples.
Water-soluble fertilizers are mostly used in intelligent greenhouses integrating water and fertilizer to grow vegetables and conventional soil cultivation of vegetables and fruits. It can be used through stem and leaf spraying, drip irrigation, micro spraying, etc.
Water-soluble fertilizers are quick-acting fertilizers and are basically applied as top dressing. Due to the relatively short duration of fertilizer effect and the characteristics of easy water loss, it is not recommended to be used as a base fertilizer.
Foliar fertilizer:
It is widely used as a fertilizer for the treatment of stems and leaves in vegetables, fruit trees and fields.
Foliar fertilizers come in liquid or granular form. The main characteristics are good water solubility, no impurities, and relatively low nutrient content. They are mainly used for stem and leaf spraying.
Foliar fertilizer is mainly used as a fertilizer supplement for the interruption of basal fertilizer. Although the leaves absorb faster, the absorption is relatively limited. The amount of fertilizer absorbed by the leaves can reach about 20-30% of the root absorption.
Therefore, it is not advisable to use foliar fertilizer as the main fertilizer application method, and it is still necessary to use the basic fertilizer application as the main fertilizer and the principle of foliar supplementation as the supplementary principle.
