Determination of boron status of olive orchars in Nizip district of Gaziantep province

Aims: The aim of this study was to determine the boron status of olive orchard in Nizip district of Gaziantep. Methods and Results: For this purpose, a total of 40 soil samples were taken from two different depths (0-30 and 30-60 cm) and 20 different points to represent the olive gardens. Texture, pH, salt, lime and useful boron contents of the soil were determined in the samples. Conclusions: According to the results of the research; pH contents of soils 7.93-8.44; salt contents of 0.010-0.043%; clay contents 33.04-61.04%; sand contents 11.68-35.36%; silt contents of 18.32-50.32%; lime contents were found between 8.11-93.28% and the contents of boron were found to be between 0.06-1.18 ppm. In terms of boron content of garden soils, at 0-30 cm depth, 85.00% is very small, 10.00% is less and 5.00% is sufficient, at 30-60 cm depth 95.00% is very small and 5.00% is low It is determined to be. Significance and Impact of the Study: In the study, it was determined that there is a negative significant relationship between the available boron content and silt content of soil. On the other hand, it was determined that while there is a negative significant relationship between salt content and sand and lime contents, there is a positive one between salt content and clay content of the soil. In addition, it was determined that whereas there is a negative significant relationship between clay content and sand, silt and lime contents, there is a positive significant relationship between silt content and lime content of the soil
