What is soil salt damage

Soil salt damage, which can also be called soil salinization, is a process in which salts from deep soil water rise to the surface with capillary water, and the water evaporates so that the salts accumulate in the surface soil. These salts in the surface soil include sulfates, chlorides, carbonates and bicarbonates of sodium, potassium, calcium, magnesium, etc. When the salt content in the top soil is too high or exceeds the level that vegetables can tolerate, growth is hindered and the dangers of soil salinization manifest themselves. In the process of vegetable cultivation, we will find in the planting row and on both sides of the dry soil surface often presents white or red, and after watering disappears, as the soil gradually dries, red and white frost will appear again. Once this happens, it means that the total salt content of the soil is already high and the soil has a tendency to salinization.


Symptoms of soil salt damage

Salt damaged vegetables due to water absorption difficulties caused by physiological drought, metabolic disorders, ion imbalance, salt affected vegetables are generally manifested as dwarf plants, stunted, dense leaf color, in severe cases from the leaves start to dry or brown, inward or outward rolled, the roots become brown to dead.

There are many problems with greenhouse soil, salt damage is particularly serious. Vegetable planting rows within the surface of the green, red, white frost and other situations is the visual performance of the greenhouse soil salt damage.
