Regarding nitrogen fertilizer, it should be said: Due to the salinity of water Iranian Pistachio and soil in pistachio-rich areas, the type of fertilizer

Consumption chemicals should be used to modify the adverse effects of salinity and toxicity of sodium ions

Be chlorine. Among nitrogen fertilizers, urea despite 46% nitrogen for pistachio-rich soils

Which also have high lime is not suitable. Because this fertilizer is in alkaline environment

Decomposes and evaporates as ammonia as well as residual bicarbonate ions

Causes yellowing of trees and lack of other nutrients. Plant bulk nitrogen case

It absorbs its need in the form of nitrate and a small part in the form of ammonium

The reason for the possible low population of microorganisms in saline soil is the nitrogen uptake efficiency of

This fertilizer is very low. The best nitrogen fertilizers that are also acidic

Can be used for pistachio areas, ammonium nitrate with 33% nitrogen and sulfate

Ammonium is 21% nitrogen.

Given that 50% of nitrogen is ammonium nitrate fertilizer in the form of nitrate, its consumption in all

Land is especially suitable in heavy soils (but preferably 2 times) because 50% of

This fertilizer is ready to be absorbed and the remaining 50% of it to be absorbed by the population

Soil microbiology is dependent.
