Abstarct: Given the ever-increasing population and the increasing need for food products, it is obvious that agricultural land management is needed to produce the highest quality products. Land management is not possible without adequate knowledge of the status of soil nutrient elements. Therefore, consideration of the status of soil nutrient elements for fertilizer management and increase of efficiency is necessary. This research has been carried out in a number of Citrus fruits of Dehdasht and Choram. At first, the site of sampling was selected randomly and then the samples were sampled with GPS sampling. The necessary tests were performed on salinity parameters, soil reaction, nitrogen, organic carbon, phosphorus, potassium, iron, and zinc with standard methods, and then the data were mapped using GIS (Geographic Information System (GIS)) and, finally, data analysis Done. Data analysis indicates that the salinity of the studied area is relatively good. Also, the organic carbon content of the area was studied, which shows that in most parts of the study area, the percentage of organic carbon is low and, in this regard, are considered as poor soils. Also, the potassium level was modest, and the salinity levels were in a favorable position and did not constrain the growth and development of the plants, in most places the amount of available zinc was too high and iron levels were low. In the end, it was concluded that this should be considered as an essential element of the increase in the elements whose deficiency is significant. It was also suggested that, considering the flat land and the proper condition of irrigation water, these areas of gardening and management of these lands should be considered more and more.
