Abstract

The soil in the study area consists of thrbe types of soils (river beds, river ponds and marshland). Their characteristics vary Because of the different factors that make up the area. The objective of the study is to study the relationship analysis statistics using factor link pearson for the extraction link quantification between productivity agricultural sector(yield) physical properties of( soil tissue, real density, density, porosity, humidity and color), as well as the chemical properties of (organic matter, soil pH, soil salinity EC, cation exchange, nitrogen, lime, Gypsum, sodium exchange, sodium soluble, positive and negative ions) and explain the reasons for the variation of these characteristics among the soil of the administrative units in the study area. The study showed that there is a strong correlation between physical and chemical properties and the productivity of some agricultural crops such as wheat, barley, maize, buckwheat, green onion, okra, eggplant, citrus, palm, sesame and fodder crops . .
