Geographical Analysis of Differences in Soil Chemical Properties in Sirwan District

Abstract

The aim of this study is to present the amount of soil nutrients and the geographical distribution of each of these nutrients in different parts of Sirwan district in different altitude units, especially in natural and unproduced soils Influence of the natural environment such as geological structures, altitude and climate types, each of these affect the soil characteristics of the region, especially geological structures such as limestone, which is the main source of calcium carbonate and calcium sulfate These settlements are formed as a result of the transport and removal of minerals and organic materials from the mountains and forests to the plains and their deposition, which leads us to the conclusion that the soil of the region contains a good amount of nutrients but in different high and low units, but these different soils have not been exploited to the extent necessary, whether due to high and low altitude or any other reason. Because these soils can be used in different forms of agriculture such as swamps and stairs, especially in highland soils. The geographical location of the study area is located in the east of Kurdistan Region and south and southeast of Halabja province, the astronomical location of the study area lies in the latitude (8°:2−:35=) to (46°:18−:35=) north and longitude (45°:45−:2=) to (46°:10−:42=) east.
