    Impacts of boron-affected water in boron-mining catchment area on soiland crops
    (2011) Cetin O.; Uygan D.; Yalcin G.
    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.

    Mapping boron pollution using gis for boron-affected soils in Western Turkey
    (2012) Uygan D.; Cetin O.
    This study was aimed to assess status of boron pollution, identification of agricultural soils at risk in Seydisuyu Watershed of Western Turkey, which has rich B deposits. The maps of borom pollution for the soils were produced using GIS. Boron concentrations in the irrigated soils varied widely, from 0.08 to 3.40 mg kg-1 depending on the sampled fields and soil depths. The highest boron concentration was found in the top layer of soil (0-30 cm) for all sampled fields. This revealed that the top layer of soil was most affected by accumulation of boron. However, there is no excessive boron pollution especially in terms of crops. Thus, decision makers, irrigators and farmers could be used these boron pollution maps for appropriate irrigation and soil management.
