One of the major problems and limitations of pistachio shell clay is its slowness

The permeability of this soil to water and air movement is ventilation. the door

Many clay soils are still wet after several days of irrigation

And is saturated with water. Long-term accumulation of water leads to impaired soil aeration

The plant's roots are damaged due to lack of oxygen. Level

Root damage in the case of plants such as the pistachio tree whose roots are relative to the condition

Ventilation is extremely sensitive, it is more intense. One of the most deliberate reasons that

The best soil texture for pistachio orchards, medium-grained sandy weaves

Sandy loam to loamy sand stated Hand, this is the sensitivity of the root of the pistachio tree

Due to lack of oxygen. To increase the permeability of clay soils

There are various ways to improve water and ventilation conditions in this land.

The most common way is to use sand to repair soil texture over the years

The latter has become very popular. There is no technical or economic justification for

There is no repair of clay soil texture by giving sand to this soil.

As can be seen within one to two years after adding sand to the soil

Clay No trace of sand can be seen even on the surface of the soil. Gravel added in between

Soil clay particles are lost. By definition, soil texture is the final percentage of particles

Minerals that make up the soil include: sand, silt and cla

Swimming is practiced and is done with pistachio dip. The difference between the three classes

Soil particles, ie sand, silt and clay, are just the physical size of these particles. generally,

Soil is called particles smaller than two millimeters. Particles larger than two millimeters

Soils are not considered soil components. The relative percentage of each of these

There are three groups of soil particles that determine soil texture. To modify and change

The soil texture should be added to the garden soil by adding soil that contains particles

The main action to be taken.

For example, to improve the texture of a heavy clay soil, you need sandy soil

Add the desired soil. Conversely to improve sandy soils can be from

Soils with a high percentage of clay were used. The important point here is the amount

It is soil that must be added to the main soil to change one to two percent sand or clay

Be. The amount of sand required to repair the texture of a clay to a depth of half a meter, several

There are a thousand trucks of sand, which is not justifiable at all

A one to two percent change in a soil texture component has no significant effect on change

It does not have the nature of primary soil.

Given the above and some other cases, the most economical way to correct

Adverse properties of a clay is the use of sulfuric acid. With

Use sulfuric acid as a modifier after two to three repetitions

Soil permeability is increased and the problem of soil aeration is solved at the same time.

By improving the ventilation status of a clay, growth and development conditions are an important part of

The causative agents of inflammatory diseases are eliminated.
