“…Addition of alfalfa residue or cattle manure to soils likely stimulated microbial assimilatory reduction of the added Se0,2 ,-, thus reducing its bioavailability. Our results support earlier studies that found a reduction in plant Se with increased organic C in soils (Bisbjerg and Gissel Nielsen, 1969;Levesque, 1974). Blaylock and James (1994) found that the addition of Mn oxides and organic acids (ascorbic and gallic acids) to some soils increased the amount of soluble Se and enhanced the oxidation of Se03 to Se04.…”

Arthur et al., 1992). Another viable strategy to supPle- chamber conditions. Tissues of canola and tall fescue accumulated much greater concentrations of Se from the inorganic Se0,2 ,-treatment compared to the treatments with seleniferous organic materials. The addition of crop residue or animal manure to the Se0,2,--treated soils considerably reduced Se accumulation by both plant species. In soils amended with seleniferous organic materials, more than 80% of the Se remained in soils after two plantings of canola and all clippings of tall fescue. The slow release of plant-available Se in soils amended with seleniferous organic materials suggests the use of these materials to control the concentrations of Se in crops grown on nonseleniferous soils.

“…Indications that organic soils retain selenium more strongly than mineral soils have been reported by Vander Eist and Tetly, 67 Levesque, 68 and Hamdy and Gissel-Nielsen. 64 Studies carried out by these and several other authors showed that the addition of organic matter greatly diminishes the evolution of volatile selenium compounds as well as the movement and leaching of selenium through soil volumes.…”

“…In contrast, other studies have shown a negative correlation between P fertilization and Se uptake by raya [26] and corn [15]. These contrasting results may arise not only from the different plant species, but also from the reported pH changes following P fertilization.…”

“…There are few known ions which affect Se uptake other than sulfate (SO*""), which is chemically and physically similar to selenate (SeOj~) [13]. Nutrient interaction studies conducted on Se-rich agriculture soils, for example, have shown that excessive use of phosphorus fertilizers increases Se concentrations in forage plants to levels potentially toxic for Downloaded by [University of California Santa Barbara] at 06:07 10 June 2016 cattle and sheep [14,15,16]. However, the reported effects of P on Se uptake are inconsistent with one another [17,18].…”

A field study determined that phosphorus concentrations influence the accumulation of selenium in the plant tissue of wild brown mustard (Brassica juncea czem L.). The main treatment was a one-way H 3 PO 4 application at five different concentrations (less than 1, 10, 25, 50, and 100 mg P/L). A constant concentration of 5 mg Se/L was added as Na 2 SeO 4 with each application. The H 3 PO 4 and Se additions were injected daily by a surface drip irrigation system. Plant dry weight yields did not vary significantly from one phosphorus treatment level to another, but plant tissue concentrations of Se and P increased, soil Se decreased, and soil P increased as H 3 PO 4 application concentrations increased. Thus, adding phosphate to the soil in irrigation water contributed to Se-accumulation in mustard and led to lower levels in the soil. 283
