Development of pedotransfer functions for prediction of soil nitrogen and its spatial distribution in conservation of Damavand’s rangelands
Abstract
In Iran, soil nitrogen is very low in most areas of production like agriculture and rangeland. This fact indicates that minor changes in soil nitrogen could have a high impact on the soil properties and soil quality in arid and semi-arid conditions. Determination of nitrogen content in soil is of utmost importance because of its role in soil physical, chemical and biological properties. This research was aimed to estimate soil nitrogen using pedotransfer functions and independent variables of soil physical and chemical properties. For this purpose, 60 soil samples were taken systematically from depth of 0-30 cm, and soil organic carbon content, pH, lime, nitrogen, sand, silt and clay were determined. According to the obtained results, the average, minimum and maximum nitrogen content of the soil was 0.846, 0.706 and 1.608 grkg-1, respectively. Nitrogen content showed the highest correlation coefficient with organic carbon (r= 0.930**, P< 0.01) and clay (r= 0.765**, P< 0.01).
