How to improve alkaline soils?

Modification of alkaline (sodium) soils, like saline soils, in pistachio shell addition to the need for leaching (at least to the same extent) and drainage (especially in clay soils) requires the use of various modifiers such as gypsum and agricultural powdered sulfur, which accelerates the reform They become, too.

Also, the use of chemical fertilizers such as sulfate fertilizers (such as potassium sulfate, iron sulfate, zinc sulfate and…) and phosphorus (superphosphates) and organic fertilizers, especially animal (cattle) fertilizers in Chalkud can be useful in improving the growth of fruit trees. .

The amount of gypsum required to replace the exchangeable sodium ion is known as the "gypsum requirement". By adding gypsum to the soil ion calcium instead of sodium ion sitting on the surface of clay soils, water permeability and soil aeration (gas exchange) are improved. Estimation of gypsum needs of alkaline lands should be done with the opinion of experts.

Calcium from the dissolution of gypsum can reduce the absorption of magnesium and potassium. Therefore, it is very likely that a deficiency of one of the elements potassium and magnesium will appear in the trees. Therefore, leaf decomposition must be done in late July, the first half of August, because otherwise the incorrect use of gypsum may show us another result. In the following, we will explain the best type and method of applying gypsum to improve alkaline lands.
