Abstract

 One of the most important criteria for obtaining quality and abundant crops in agricultural production is a sufficient level of soil organic matter content. It is very important to ensure the use of natural coal-based organic matter resources such as gyttja and leonardite, which are available in our country, in agricultural areas. Sirnak is a province with rich coal deposits. In this study, some properties of asphaltite samples taken from mineral reserves in Sirnak province were investigated in terms of their usability in agriculture. For this purpose, pH, electrical conductivity (EC), lime (%), organic matter (%), ash (%), and humic acid (%) contents of the asphaltites were determined. According to the results of the research, the average pH of the asphaltites was determined as 7.58, EC as 2.95 mS cm-1, and lime content as 28%. Organic matter contents ranged from 32-40%, with an average ash content of 38% and an average humic acid content of 8.8%. Although the organic matter content of the asphaltites in the region is high, the humic acid level is low.
