What is the significance of fertilization in nursery?

"Fertilizer is the food of plants", and fertilization is an important measure to cultivate strong seedlings. Carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, iron, molybdenum, boron, manganese, copper, cobalt, zinc and other elements 10. Except for carbon, all the carbon needed for plant growth comes from soil. Fertilization can supplement all kinds of nutrients needed by plant growth in soil and meet the needs of seedlings for nutrients.

Fertilization can improve the physical and chemical properties of soil, especially organic fertilizer, which is beneficial to the formation of aggregate structure and the coordination of water, fertilizer, gas and heat supply in soil.

Fertilization, especially humus fertilizer, can promote the activity and reproduction of soil microorganisms, accelerate the decomposition of insoluble nutrients in soil, and also produce hormones and antibiotics to stimulate plant growth.
