In connection with the nutrition of pistachios, pistachio shell the first step at the beginning of the autumn season is the spraying of gardens with elements whose role in the strength, stability and survival of the next year's buds has been proven. For post-harvest spraying with a combination of zinc chelate, urea (3 per thousand) and calcium chelate is recommended for many orchards.
In addition, during the autumn period and inactivity of the pistachio tree, winter repair and fertilization operations can be started. The most important improvement operation that the soil of some pistachio orchards needs is to give agricultural gypsum to the orchard. Plastering is a way to improve alkaline and low permeability soils.
The best time to apply the plaster to the soil is during dormancy or low root activity, where there is a possibility of heavy irrigation after applying the plaster. To determine the amount of gypsum, it is necessary to know the soil texture, sodium uptake ratio (SAR), calcium to magnesium ratio and salinity of irrigation water. The decision to give gypsum and the amount of gypsum required for one hectare of garden should be made with the advice of relevant experts.
