“…Dhillon and Dhillon (1999) centage of the sorbed Se in water-soluble SeO 2À 4 form. Significant positive coefficients of correlation between CaCO 3 content, available Se in soils, and Se concentration in plants in the seleniferous region of Punjab (Dhillon et al, 1992) indicate that Se adsorbed on CaCO 3 particles is easily accessible to plants for absorption. Adriano (1986) has reported that Se tends to concentrate in carbonaceous debris in sandstone.…”

“…Total Se content of the soils in the affected region varies from 0.08 to 4.55 mg kg ±1 . The soils containing >0.5 mg Se kg ±1 are considered seleniferous because crop plants raised on these soils absorb Se more than the maximum permissible level of 5 mg kg ±1 animal feed (Dhillon et al, 1992). It has already been documented that humans consuming food grains in these soils exhibit symptoms like loss of hair and nails and progressive deterioration of health (Dhillon and Dhillon, 2003a).…”

Experiments were conducted to study drainage and runoff losses of selenium (Se) from two seleniferous soils (from Simbly containing total Se 850 lg [kg soil] ±1 and from Barwa containing 1310 lg [kg soil] ±1 ) under simulated rainfall (250±260 mm in three rainstorms) conditions. Rainfall intensities ranged from 56 to 120 mm h ±1 with uniformity coefficients ranging from 70.6% to 84.2%. Selenium lost through drainage (sum of drainage from initially saturated soil for 24 h and through dry and wet runs) was 0.15% and 0.11% of total Se content in the two soils. In soils having similar pH and organic-C content, losses of Se through drainage as well as runoff were defined by total Se, water-soluble Se, CaCO 3 content, and texture of the soils. The amount of runoff water was almost two times in the soil with fine texture and less infiltration rate than in the other and that same trend was observed with respect to loss of sediment. The soil with higher CaCO 3 content and water-soluble Se lost more Se with moving water both through leaching and runoff, whereas the other soil with fine texture lost greater amount of Se with the sediment. Total Se lost through drainage as well as runoff was 0.29% of the native Se present in both the soils suggesting that significant amount of Se could be lost from seleniferous soils during irrigation and rainfall events.

“…This was done to study the accumulation of Se by sugarcane plants growing near the permanent bundhs and in the rest of the field. As in case of wheat, Se toxicity symptoms at first appeared in plants growing near the permanent bundhs and/or permanent water channels (Dhillon and Dhillon, 1991).…”

“…Recently Se toxic areas have been identified in some parts of Hoshiarpur and Jalandhar districts of Punjab, India (Dhillon and Dhillon, 1991). Sugarcane is one of the major crops in the region and farmers use the sugarcane tops as fodder for animals over a large part of the year.…”

A survey was conducted during 1986-88 to assess the level and pattern of accumulation of selenium in sugarcane plants in seleniferous areas of Punjab (India). Total and water-extractable (available) selenium ranged from 0.55 to 2.58 (mean 1.43 ± 0.67) mg kg(-1) and from 0.02 to 0.05 (mean 0.033 ± 0.007) mg kg(-1), respectively, in seleniferous areas. Corresponding values from non-seleniferous areas were 0.23-0.55 (mean 0.36 ± 0.08) mg kg(-1) and 0.015-0.025 (mean 0.020 ± 0.003) mg kg(-1), respectively. Sugarcane tops from seleniferous areas accumulated high levels of selenium ranging from 7.9 to 67.5 mg kg(-1). These selenium levels were 6-14 times higher than those from non-seleniferous areas. During the early stages of growth (June), the selenium content was highest but decreased during the months of July and August and then did not change up to maturity. In the seleniferous areas sugarcane tops and canes at maturity contained 5.7-9.5 and 1.8-2.1 mg Se kg(-1), respectively. However, the tops and canes of plants growing near the permanent boundary (bundh) contained 9.5-18.8 and 2.1-2.4 mg Se kg(-1), respectively.In a field experiment on sugarcane, application of gypsum up to 1 ton ha(-1) resulted in a significant reduction of selenium content in sugarcane tops as well as in the cane. Selenium content in sugarcane tops at maturity was reduced from 15.16 to 5.08 mg kg(-1) by applying gypsum of 1 ton ha(-1).

“…Some studies have shown that continuous rotation of cereal-cereal (rice-wheat) cropping system has resulted in negative impacts in organic carbon (OC) content 2 , while other studies have shown its positive impact on OC 3,4 . Cultivation of rice on light-textured soils in recent/active flood plains has resulted in lowering of the water table 5,6 , creation of hard pan in the subsoils, increase in soil organic carbon (SOC) 7 , and increase in selenium toxicity which adversely affects human as well as animal health 8,9 . Soil erosion by seasonal streams (choes) in the northeastern parts of the district, especially Balachaur tehsil, low water-holding capacity in steeply sloping lands in the foothills of the Siwaliks, sandy soils of choes and recent/active flood plains 10,11 , and small land-holding size are the other major problems in the area.…”
