Determination of boron status of the lands of Reyhanli-Kumlu region

In this study, it was aimed to determine some physical and chemical properties and available boron status of the soils of Hatay Reyhanlı-Kumlu region. For this purpose, a total of 80 soil samples were taken from 0-20 and 20-40 cm depths and 40 different points to represent the soils of Hatay province Reyhanlı-Kumlu region. In the soil samples taken, pH, texture, cation exchange capacity (CEC), exchangeable cations (EC), lime, organic matter and available boron values were determined to determine some physical and chemical properties of the soils and the available boron status. According to the research results; clay content of the soils is 15.84-76.56%; sand contents 0.72-51.44%; silt contents 16.72-47.28%; pH contents 6.86-8.44; total salt contents 0.007-0.070%; lime contents 2.71-64.23%; organic matter contents 0.40-2.89%; KDK contents 26.43-91.13 me/100 g; Na content 0.21-4.51 me/100 g; The K content was found to be between 0.59-5.81 me/100 g and the available boron content was between 0.07-1.76 ppm. As a result, the available boron content in the soils of the study area was determined at a low or very low level over 78%in the soils of the study area, and it was observed that the available boron content of the soils was insufficient and therefore boron fertilization was required.
