The Use of the System Sys Land Evaluation System in the Evaluation of Gypsum Lands for the Cultivation of Peanut Arachis Hypogaea Irrigated in the Al-Tarrah Region, West of Anbar Province

Abstract

Abstract Land assessment is one of the most important tools for integrated management of sustainable agricultural land use and land use planning. to achieve this, field visits were carried out and, depending on the factors of elevation above sea level and the prevailing land use type, 8 soil troughs and drill holes were dug in the study area with a depth of 120 cm The number of which is (48) so that it is representative of the studied region. The samples were taken in a systematic way, to perform physical and chemical analyzes such as tissue (%rum, %silt, % clay, % organic matter, cation exchange capacity, and others). The results of soil analysis showed the difference in the influence of physical and chemical determinants, and the biggest determinant of peanut cultivation was the amount of gypsum and pH values as an average determinant. The final total estimate of the climate factor is not a determinant of the growth of the field pistachio crop in the study area. The study found that the types of suitability ranged from N1 to N2.
