Pistachio land irrigation systems

If a flood irrigation system is considered, the final slope of the land Iranian Pistachio should reach about 1-2%. If, according to the results, corrective operations are necessary at the planting site, then it is possible to add gypsum or sulfur and rotten animal manure to the soil in the planting strip and then plant the seedlings.

It should be noted that in order to improve the soil (if the soil pH is higher than 7.5 or 8), by measuring the exchangeable sodium and considering its optimal amount, the amount of gypsum or sulfur required per hectare is calculated and Be given to the earth. Of course, it should be boe in mind that the effects of this soil remediation will appear and be observed in the long run and at least 2 to 4 years later.

If the animal manure used is completely rotten and free of weed seeds, it can be poured into the seedling planting strip and sulfur can be added to it. It should be emphasized that giving gypsum alone can improve the soil, but giving sulfur without animal manure is of no use.
