The correct method of using potash pistachio wholesale fertilizers in pistachio orchards
Unfortunately, in the past, due to the lack of potash fertilizers in pistachio orchards and excessive depletion of potassium in the soil, trees have faced long-term problems. Statistical studies show that more than 60% of gardens in Kerman province are deficient in potassium and it is difficult to bring the yield to the desired level in these gardens in the short term.
Since the need for potassium in pistachio trees is the same as nitrogen (slightly less) and given that potassium has a very important role in the quantity and quality of the product should be given special attention. Potassium plays an important role in regulating the water system and plant sap concentration, which is vital in arid and saline soils. In case of symptoms of deficiency of 1-3 kg of potash fertilizer for each tree in the form of manure or fertilizer tape is recommended. 48% of potassium, potassium chloride is recommended only in non-saline soils.
The correct way to use potash fertilizers in pistachio orchards Since the tree needs high nitrogen and potassium when the fruit is full and the simultaneous use of these two elements will have a great impact on the quantity and quality of the product, the use of potassium nitrate can be very useful. It seems that the nitrate in these fertilizers, in addition to meeting the need for nitrogen, also prevents the absorption of chlorine and increases the efficiency of potassium uptake. Therefore, it is recommended to use one third of the potash and nitrogen requirements of the plant as potassium nitrate road, and if more nitrogen is needed, to use ammonium nitrate, and the rest of the potash needs to be consumed as potassium sulfate (chalk fertilizer).
