The Department of Geography and Geographic Information Systems at the College of Arts at the University of Basrah discussed the water tension of different textured soils from Basrah Governorate and its effects on growing plants.
The researcher Jamila Jassim’s thesis included three chapters in which she explained the natural factors affecting the water tension of soils of different textures from Basrah Governorate, the human geographical factors affecting the water tension of the soil in the study area, and the physical and chemical characteristics affecting the variation in the values of water tension and their effects on growing plants.
The thesis aims to clarify the relationship between the natural geographical and human factors affecting water tension, in addition to studying the most important physical and chemical properties and their effects on the occurrence of water tension and the variation in the values of soil water tension, which falls within the maximum limit for soil water preservation.
The thesis concluded that natural geographical factors have a prominent and influential role in determining the values of water tension at field capacity rates and the wilting point, and human geographical factors also have an influential role, represented in the agricultural operations carried out by the farmer, in addition to the influence of positive and negative ions, electrical conductivity values, and soil salinity.
The thesis recommended stopping the process of bulldozing agricultural lands, cleaning and burying all the exchanges and the irrigation canal, and making efforts and educating farmers about using fertilizers correctly, in addition to providing farmers with the supplies they need in the agricultural process, and supporting them in all aspects in order to support and continue productivity, stop soil deterioration, and follow correct scientific methods.
