Construction slag is the most important factor limiting the penetration pistachio shell of sufficient water into the soil

is. As mentioned, Quba is the most effective tool against low soil permeability

And its closure is the strength and stability of aggregates. Water-soil factors

Important in permeability and loosening of soils that are easily measurable and controllable

Are:

1 (Total salinity measured by EC)

2 (SAR sodium uptake ratio)

3 (PH acidity)

Familiarity with the operation and possession of EC pistachio extract is an important factor in determining

It is a series of soil closures. However, the water around the soil particles is soil water

It is significantly affected by the composition of irrigation water. Reduction of EC in water

Soil increases the swelling of clay particles and thus reduces the size of soil pores

Irrigation water with EC less than 0.3 dS / m for most soils

It is difficult. For each soil a certain unit of salinity threshold of soil water

There is less than that, the act of dispersing soil particles occurs. Action

Dispersion of soil particles is significantly affected by the ratio of sodium to calcium

And there is magnesium, which is called the sodium absorption ratio. Generally with increase

Salinity and reduction of SAR, aggregate strength increases.

In some soils there is a large amount of serpentine clay, these clays from

MG is rich in magnesium and relatively low in Ca. In such an environment

Magnesium may behave similarly to sodium and cause soil instability.

Dispersion of its particles and reduction of permeability.

Some experts believe that when the ratio of magnesium to calcium is 1: 1

In most soils with serpentine clays, permeability problems may occur

Do not develop. Soils rich in exchangeable potassium may also be

Face penetration problems. Some reports suggest that

Potassium may have sodium-like effects when potassium is the predominant cation in the soil

On the stability and porosity of the soil. In this case, soil stability is reduced,

Aggregates are dispersed on the surface and create a barrier for water to penetrate the soil surface

Soils rich in Montmorlonite and Illite clay with increasing amount

Magnesium is easily dispersed. Hydrogen peroxide, iron and organic matter cause

Stability of clay particles so that they are practical, as opposed to the effects of dispersion of soil particles

They do it due to sodium water or water with very low salinity.
