What are the suitable fertilizers for pistachios in the spring season?

Beginning of germination

As mentioned, nitrogen and phosphorus are the most important elements needed by pistachios. Especially in early spring and when the trees wake up and the first buds appear. Iranian Pistachio

 

In order to supply the nitrogen needed by the tree at this time due to the coldness of the soil, ammonium fertilizers are recommended, which have the highest amount of absorption. One of the suitable pistachio fertilizers that can be used at this time is ammonium sulfate.

 

Urea phosphate fertilizer is one of the best fertilizers suitable for pistachio at this time to supply phosphorus needed by the plant. It is very necessary to use these two fertilizers in the early spring because of the essential role of these two elements in the germination of the quality of the brains, the production of energy-transmitting substances, etc. In the following, we will talk in detail about the effect of different elements.

Scaling of vegetative and reproductive buds

When most of the trees in the garden have slightly opened the scales of the buds. At this time, it is possible to increase the fruiting rate of the tree by spraying Fruit set, which contains a combination of amino acid, zinc, boron, iron, nitrogen and other micronutrients, and increase the yield. Of course, fruit set can also be used after harvesting, this increases the tree"s resistance to cold and increases the quantity and quality of the product in the following year.

 

brain formation (late June and July)

This time is the best time to use potash fertilizers, which helps to increase the quality of the nuts. The types of potash fertilizers that can be used for this purpose are potassium sulfate, sulpotas and potash solution.

 

Suitable pistachio fertilizers to prevent nematodes

Nematode is actually a disease in plants that causes knot-like parts to form in the root, and the nutrients absorbed by the root remain in these knots and do not reach the plant, gradually causing dryness and destruction of the tree.

 

To solve this problem by feeding the tree, one should consume more amounts of potash and phosphorus fertilizers, and the use of silica, calcium and sulfur can help to eliminate nematodes.

 

This disease usually occurs in light and sandy soils and leads to serious damage to plants in these soils. Therefore, you must be very careful in sanding or using animal manures that lighten the soil. Also, in these soils, fertilization should be done in several stages and irrigation should be reduced in order to prevent leaching of fertilizer. Also, excessive consumption of nitrogen fertilizers increases the risk of nematodes, so the consumption of nitrogen fertilizers should be reduced in these soils.
