How to fertilize avocado

Avocado fertilization technology

Generally speaking, avocados are fertilized with nitrogen fertilizer more than four times a year, usually by broadcasting or by irrigation systems. When adult avocado trees are in the young fruit stage, each tree should be applied with about 50 kilograms of organic fertilizer and about 50 grams of compound fertilizer. Double the fertilizer should be applied after the fruits are picked.

If the leaves show symptoms of phosphorus and potassium deficiency, it is necessary to supplement phosphorus and potassium fertilizers in time. Zinc fertilizer can be applied on some soils, or foliar spraying can be used. Foliar fertilizer is most effective when new leaves grow in spring. If the plant is grown in calcareous soil or soil with a relatively low oxygen content, a chelated iron solution can be applied to the roots.

Some soils and irrigation water sources contain nitrogen, in which case the amount of nitrogen fertilizer used should be reduced; if the tree has few new leaves growing, the leaves are grayish white, and the fruit is relatively large, the amount of nitrogen fertilizer applied should be increased.
