Everyone knows how important soil is to living things. It is no secret that we always call the land the motherland. The land also plays an important role in cotton growing. Like all plants, the main food source of cotton is fertile soil. Therefore, special care is taken to ensure that the soil is always soft, moist and rich in nutrients. In general, cotton can be grown mechanically in many soil types. Mechanically light clay soils are the most suitable type of soil for growing cotton. If the soil is heavy clay, it is not suitable for cotton growing, but if the heavy clay soil has a high level of fertilization, irrigation and care, it is possible to get a cotton crop.
Soil Structure (Grain)
Another nuance in the cultivation of cotton is the structure of the soil. The more structured the soil, the better the growth of the plant. In unstructured soils, however, there is a lot of crust, and therefore the water-physical properties are not suitable for plants. When the soil is unstructured, the newly mature seedlings of the cotton plant develop poorly, and the crust in the soil creates a density in the root collar of the weak seedlings. If the soil is unstructured, in hot weather the bark layer heats up and the weak seedlings of the plant perish. Often it is not possible to get seedlings in this type of soil and sowing is repeated.
Brine Waters
If the soil layer is thick, favorable conditions are created for the normal growth and development of the plant. In addition, the depth of groundwater also plays a role in the good development of cotton. The closer the saline groundwater is to the top of the soil, the more harmful it is to plants. In order for saline water to be considered safe for cotton cultivation, it must be more than 3 meters deep.
Salinity of the soil
The main cotton-growing areas in our country are the lands of the Kur-Araz lowland. Most of these lands are in the form of gray-brown, gray-meadow, gray and meadow-swamp. Sulfate, chloride and sulfate-chloride salinization have occurred in this type of soil. The cotton plant is slightly tolerant of salinity but suffers from poor plant growth when the salt content is high. If the value of salt in the soil where cotton is grown is high, the water regime of cotton is violated and the development stage is seriously damaged. It can even lead to the destruction of the plant. If the salinity of the soil increases slowly, the resistance of cotton to salinity increases and develops normally. In overly saline soils, the cotton crop shrinks, evaporates, and yields decline. As a result, varieties resistant to salinity are grown and various measures are taken against salinization.
