Three types of fertilizers to be chosen with caution during the seedling stage of crops

Three types of fertilizers that should be carefully selected during the seedling stage of crops. The seedling stage is a period when the growth of crops is relatively fragile. Improper fertilization and management can affect the growth of seedlings and even be harmful to plants. This is true for both young trees and crop seedlings. Fertilization during the seedling stage should be carried out with caution, avoiding the application of uncompletely decomposed organic manure, high-concentration quick-acting fertilizers, and excessive fertilizers. 
During the process of the embryonic root growing after the plant seed germinates, it pushes the new sprout out of the soil, and at the same time, new root systems grow. The new roots are quite sensitive to the external environment, and unsuitable soil and fertilizer and water have a significant adverse effect on the growth of new roots. The root system continuously absorbs nutrients, water and various inorganic nutrients from the soil and transports them to other parts of the plant.

If uncompletely decomposed farmyard manure is applied to the soil, it will undergo secondary fermentation, generating heat and organic acids, which can cause root burning and even plant death. The growth of young plants mainly relies on vegetative growth and requires quick-release nutrients. Excessive nitrogen concentration often affects the normal growth of the root system. Excessive nitrogen fertilizer can cause root burn. Young plants should be fertilized in small amounts and multiple times. Excessive fertilization at one time will cause the soil solution concentration to be too high, and the roots will not be able to absorb nutrients. Instead, the water inside the roots will seep out, leading to the death of the young plants and other phenomena.
