Plants need more sulfur than phosphorus. Sulfur pistachio shell concentration inside the plant
It is much more familiar with the practice of cutting and holding pistachios than phosphorus
That sulfur plays a role in plant protein formation as much as nitrogen. Most soils
The country's agriculture is calcareous and irrigation water is also high in bicarbonate. one of
Methods to improve nutritional management in calcareous soils with high bicarbonate irrigation water,
Use sulfuric acid. Because the consumption of this acid in farms and gardens
The fruit of the country is associated with many problems, including burns, so with
With the help of Thiobacillus bacteria, sulfur is converted to sulfate. Because bacteria
Thiobacilli have the ability to convert sulfur to sulfuric acid
To convert. By topical application of this fertilizer, chalk fertilizer, tape and… acid are produced
Phosphorus release from existing phosphate soil. Thus reducing the pH of the soil
In the root zone of fruit trees, increases the ability to absorb phosphorus
Soil phosphate and other micronutrients present in the soil for the plant
To be. In addition, elemental sulfur S can not be used for plants, but bacteria
Thiobacillus can be used by oxidizing sulfur and converting it to so4 sulfate
They provide an element of sulfur. Topical decrease of soil pH can be
Help lower the pH of sap within the vessels of trees and this will increase
Ability to use important nutrients such as phosphorus, iron, zinc and… for trees
Turns. As a result, in addition to increasing performance, quality improvement is also provided.
According to the recommendations of experts and researchers in plant nutrition, the amount of 1 to 2 kg of sulfur
For each fertile tree by sowing or strip method every two years
Recommended. Of course, this fertilizer must be accompanied by a sufficient amount of Thiobacillus bacteria
To be used.
5- Low consumption elements
Among the trace elements, zinc, boron, manganese and iron are important in pistachio nutrition
Have more. Based on the results of soil decomposition in most pistachio-growing areas
Province and country, more than 95% of pistachio orchards, highly absorbable zinc
Low and deficient in zn, familiarity with the practice of cutting and having with pistachio
The symptoms are in the form of baldness and petiole of rosette, especially in
Seen early in the growing season. Foliar application with zinc sulfate 5 per thousand before
Greening of the tree or 5 per thousand in May or foliar spraying with soluble fertilizers
With high zinc content or foliar application with complete micro-mineral fertilizer in May
Recommended for zinc supply. Decomposition of soil and leaves in pistachios indicates
Adequacy but also the extent of boron poisoning in pistachio orchards with saline soil and water,
is. But in areas that do not have saline soil and water, due to the high need for trees
When the fruit is formed, spray the boron before the flowers open in late March
It is essential. Another important element in the nutrition of pistachios is molybdenum. Molybdenum element
In the stage of bud swelling and flower flowering in pistachio trees is very important.
As we know one of the forms of nitrogen in the post-harvest stage and
The swelling of the buds has been emphasized a lot, it is the nitrate form of nitrogen
The advantage of nitrate compounds is that they can be stored in cell vacuoles
Be. It is here that the element molybdenum causes the decomposition of nitrate compounds and
Provides them to other organs and organs rather than to interactions
Cellular and assist in sensitive processes such as flowering.
