| Abstract | ||
| The problem of salinization of agricultural lands in Iraq is one of the main problems that led to the deterioration of the agricultural sector, and the high levels of salinization in the soil not only means the loss of more agricultural lands, but also a decrease in its productivity. Reports indicated that 60-70% of the lands in central and southern Iraq It was affected by salinity and became outside agricultural exploitation, and the agricultural expansion horizontally and vertically in Nineveh Governorate led to the transformation of demi-cultivating into irrigated agriculture for most areas of the governorate, but the agricultural misuse and waste in the use of water turned most of the soils into affected by salts. In order to improve plant growth and agricultural production in salt-affected soils, excess salts must be removed from the root zone. As for the commonly used methods for the reclamation of these soils, they are the scraping of salts from the surface, which are suitable for soils with little permeability, and washing using large quantities of water with cultivation, and taking into account that saline soils prevail in arid and semi-arid regions, in addition to the scarcity of water in these areas, in addition to the costs exorbitantthis method is considered useless, and recently there has been increased interest in using modern technologies to treat the problems of soils affected by salts and through the concept of auxiliary plants (plant – assisted concept) within the method of phytoremediation, which includes growing plants capable of collecting salts and harvesting them in order to rid them from the soil In addition to the possibility of irrigating it with salty water due to the scarcity of fresh water. | ||
