Abstract:
The present study aims at assessing the pollution type in the soil of the banks and Basins in Rumaitha city and its effect on the agricultural production. It is divided into three chapters : chapter One is devoted to investigate the natural Factors which are represented by (the location of the sample area, its geological and surface structure, climate properties, water resources, and natural plants) and humanistic Factors which are represented by (tilling and adjustment, irrigation, drainage and fertilization of the soil and the agricultural system). Chapter Two is concerned with the physical and chemical properties of the soil of the sample area while chapter Three investigated the Geographical distribution of soil pollution in the city of Rumaitha in which it discusses the definitions of pollution, its causes and effects on the agricultural areas. Some samples of soil and water were gathered during the period of the study (2015 - 2016). The study has concluded the following : Chapter OneThe results of the analysis of the banks and basins soils structures has shown contrastive mixtures of mud, mud - silt, and mud - silt - mud. Also the Virtual and real density of the soil is variant in the banks and basins. Moreover, the value of the organic material and soil reaction, and the average of the positive and negative ions, are variant too. Chapter Two The study shows that the geographical and humanistic factors have huge effects on some of the physical and chemical properties of the soil of Al - Rumaitha city and its relation to the agricultural production. Throughout the geological structure, surface equability, climate properties, paucity and scatter of natural plants, the quality of irrigation water, and water and salinity grade, several aspects of soil construction were identified which are reflected on the real structure and density of the soil. Moreover, it contains organic materials, salinity, and Positive and negative ions which are intensive in the soil of the basins rather than the banks of the river. The human has a big negative influence on these properties because of his wrong agricultural methods which are represented by tilling the soil, excessive irrigation especially in the unsuitable periods of irrigation, following the traditional methods in irrigation, the Scarcity of broaches, the wrong use of Chemical and organic fertilizers pesticides. All of these factors helped in the process of soil pollution and the intensity of salinity and heavy materials.Chapter ThreeThis chapter is concerned with salinity and osmotic pressure and mutual sodium and positive ions such as calcium, magnesium, sodium, and potassium, and negative ions like chlorine, sulfates, and bicarbonates as well as their importance to the plants. The role of the heavy factors to the developing plants appears during the germination, branching, flowering, and maturity stages and on the agricultural production as a whole. Although there are some factors of pollution, the soils of Al - Majid and AL - Najmi townships were the best in producing the various agricultural crops. While there is a decrease in production of Al - Hilal township especially on the banks of the river because they receive a lot of water pollution. It was also concluded that the soils of the banks are higher and better in their productive capability than the drains which are highly effected by the salinity and the intensity of heavy materials in addition to the bad management of the soil. The results of the analysis have shown that the city is copious with the various types of agricultural corps like grain, and vegetables. Sesame plant is the prominent in planting and production because of the suitable soil, and its capability to endure salinity which is scattered in farmlands.
