Impacts of boron-affected water in boron-mining catchment area on soiland crops

This study was carried out to evaluate the impacts of boron (B) pollution and seasonal variation in irrigation water and soils in which Seydisuyu catchment area had boron-mining enterprise of Eskisehir, Turkey from 2002 to 2003. Boron concentration in irrigation water and irrigated soils varied from 0.87 to 3.38 mg 1 -1 and from 0.08 to 3.40 mg kg -1, respectively, depending on stage of the irrigation season, source of irrigation water and soil depth in B-affected irrigation water and Bmining catchment area. In addition, the ranges of levels of boron in leaf tissue of wheat, sugar beet, sunflower, and corn were 15-132, 21-33, 23-93, and 13-37 mg kg -1, respectively. The tolerance limit for boron in water could be 3.38 mg I -1 for tolerant crops in this region.
