What fertilizer is best for olive trees?

Olive tree topdressing time

Olive trees can be top-dressed during the growth period of new shoots, mainly with nitrogen fertilizer, combined with liquid farmyard manure such as manure and urine, to promote and strengthen the shoots.

What fertilizer to use for olive trees?

Spraying 0.05% borax during the spring flowering period of olive trees can promote pollination and fertilization and increase the fruit setting rate. Spraying urea plus potassium dihydrogen phosphate during the young fruit stage can reduce fruit drop and promote fruit enlargement. Spraying 0.5% potassium sulfate in June and July can increase the fruit size. Spraying 0.2% potassium dihydrogen phosphate during the flower bud differentiation period can promote flower bud differentiation.

Is urea or compound fertilizer used for topdressing olive trees?

Compound fertilizer is used as topdressing for olive trees. Compound fertilizer contains more nutrients that can meet the growth needs of the plants. High-nitrogen compound fertilizer should be used mainly in the seedling stage, combined with phosphorus and potassium. Accelerated high-nitrogen compound fertilizer should be applied before and after each secondary shoot growth period. Compound fertilizer should be applied to fruiting trees to increase yield.

Olive tree topdressing method

1. Soil fertilization: When applying soil fertilization, fertilizers should be applied to places where the roots are concentrated as much as possible to fully exert the fertilizer effect.

2. Foliar fertilization. Foliar fertilization is an auxiliary fertilization method and cannot replace soil fertilization. However, due to the short distance of nutrient transportation of foliar fertilization and the fast effect after spraying, it is especially effective in preserving flowers and fruits.

Olive tree topdressing precautions

In olive tree cultivation, the time and amount of fertilization are determined according to the age of the tree, tree vigor, fruit yield, soil fertility, etc. Generally, pre-flowering fertilizer is applied in March in spring, with medium-speed effective fertilizer combined with farmyard manure, and fruit-enhancing fertilizer is applied from August to September. After the fruit is harvested, farmyard organic fertilizer and large amounts of elements such as nitrogen, phosphorus, potassium, and calcium can be applied again, and the soil should be turned over, applied deeply, and covered in time.
