Where is the best position for fertilization of fruit trees?

The fruit tree mainly relies on the root hairs in the root system to absorb nutrients. Therefore, fruit trees should be applied to the edge of the canopy or slightly further away from the tree trunk. Do not be too close to the trunk because the roots are thick and the roots and root hair are less, which is not conducive to the absorption of fertilizer.

Fruit trees should be mastered according to the following principles: fruit trees with deep root distribution should be applied in depth, and shallow application; organic fertilizer decomposition is slower, but the fertilizer application period is longer, and it can be applied deeper. The fertilizer has large mobility and can be applied shallowly. For example, if organic fertilizer is applied to deep-rooted fruit trees such as pear trees, the depth should be 40-60 cm, and organic fertilizer should be applied to shallow-rooted fruit trees such as plum trees, and the depth should be 30-40 cm. After fertilization, it is best to spray a new high-fat film to improve fertilizer efficiency.

For orchards that are closed or densely planted, they can be applied between rows and between plants. It is best not to hurt or damage large roots, so as to fully exert the fertilizer efficiency, improve the utilization rate of fertilizer, and achieve the purpose of increasing production and income.
