Modeling of Some Properties of Solhan Plain Soils

This study aimed to show the spetial variability and distribution of certain soil properties of the Solhan Plain in Bingöl using data derived from soil quality parameters such as organic matter, cation exchange capacity, and available water content. Soil samples were collected from 85 different coordinates at a depth of 0-30 cm, with sampling points arranged in a 300 m x 300 m grid using ArcGIS 10.8 software. Laboratory analyses were conducted to determine the available water content (AWC), cation exchange capacity (CEC), and organic matter content (OM) of the soil samples. The results revealed that the AWC of the Solhan Plain ranged between 1.06% and 25.27%, with an average of 10.15%. The CEC varied from 35.38 to 85.28 cmol.kg-1, averaging 60.53 cmol.kg-1. The organic matter content ranged from 0.84% to 4.76%, with an average of 2.50%. For the soils in the study area to perform their desired functions, their physical, chemical, and biological quality must meet the required standards. Therefore, maintaining and even improving soil functionality depends on appropriate management systems and land use practices. In areas where soil quality is low, practices such as crop rotation and manure application can positively impact the physical, chemical, and biological properties of the soil in a short time. Conversely, poor land management practices can further degrade already weak soil properties. This study emphasizes the importance of providing farmers, land managers, and decision-makers with the necessary information to make informed and effective decisions regarding sustainable land use and soil health improvement practices. This study emphasizes the critical role of soil quality in ensuring sustainable agricultural production and environmental health. By understanding the spatial variability of soil properties like AWC, CEC, and OM, stakeholders can make informed decisions to improve soil functionality and resilience. The findings underscore the need for integrated soil management practices that balance productivity with conservation, ensuring the long-term sustainability of the Solhan Plain and similar regions.
