What is the best fertilizer for navel oranges?

Navel orange fertilization time

Young navel orange trees need to be top-dressed once in early March, early April, late May to early June, late July and mid-November each year to provide them with sufficient nutrients.

For navel orange fruit-bearing trees, apply bud fertilizer between February and March, apply quick-acting nitrogen fertilizer as fruit-stabilizing fertilizer when the flowers fade, apply fruit-strengthening fertilizer mainly composed of nitrogen and potassium combined with phosphorus fertilizer, and organic fertilizer can be applied when harvesting the fruit.

What fertilizer to use for navel orange

1. The base fertilizer for navel oranges is mainly decomposed organic fertilizer, with appropriate amounts of quick-acting K, N, and P fertilizers. It is applied as winter fertilizer after fruit harvesting, which can not only improve soil structure, but also help restore tree vigor and increase nutrient reserves.

2. For navel orange fruit-stabilizing fertilizer, foliar fertilization is mostly adopted, which is applied once every half a month with a small amount of N fertilizer, P and K fertilizers combined with an appropriate amount of fruit-preserving agent. The fertilization effect is better.

3. The fruit-enhancing fertilizer for navel oranges is mainly fast-acting N and K fertilizers, combined with P fertilizer to promote fruit enlargement and provide sufficient nutrients. At the same time, it supplements the tree's nutrition, promotes full autumn shoots, increases the tree's carbohydrate level, and lays a sufficient nutritional foundation for flower bud differentiation.

Navel orange fertilization method

There are two main methods of fertilizing navel oranges: soil application and foliar spraying. Soil application involves trenching and broadcasting. Trench application can be done in the form of ring trenches, radial trenches, or strip trenches. The trench depth should be 15-40 cm to facilitate root absorption.

Notes on fertilizing navel orange

When spraying the leaves of navel oranges, you must control the concentration. If the fertilizer used is too concentrated, it will easily cause leaf burns. If the concentration used is too dilute, the fertilization effect will be poor.
