It is very important to conduct research before using water sources for irrigation purposes, to take samples of water and determine its suitability for irrigation. Particularly, attention must be paid to the quality norms of irrigation water for plants to be planted in the farm. Thus, the presence of a certain amount of salt in the water is considered suitable for some plants. However, re-salinization can occur when the amount of salts in the water is too much.

The permissible level of salts in irrigation water in our country is 1-1,5 g/l. The use of weakly alkaline water for irrigation does not give good results. For example, water containing soda affects the physical and chemical properties of the soil and reduces its fertility. Analysis of water also allows to determine the amount of asılı gətirmələr in it. This also affects the choice of filters used in advanced irrigation and allows to reduce additional costs.

Determining the temperature of irrigation water is also important. Thus, irrigation with cold water has a negative impact on growth of the plant. Therefore, if it is necessary to irrigate with such water, then the water can be used for irrigation after being heated beforehand in special pools for a certain period of time. Taking these factors into account once again shows the importance of analysis of irrigation water.
