“…In the greenhouse experiments, plants grown in the loam soil with its relatively low organic matter content, did not take up more Se when pH increased from pH 5.2 to pH 5.9, whereas they took up significantly more Se with a pH change from 5.9 to 6.4 (Table 4). This is in accordance with several studies conducted in mineral soils with a relatively low organic matter content (e.g., Cary and Allaway 1969;Lindberg and Bingefors 1970;Johnsson 1991). The effect is expected since selenate is present to a greater extent at nearneutral pH values and is less effectively bound in the soil compared to selenite (Gissel-Nielsen et al 1984).…”

The objective of the present study was to investigate the influence of soil organic matter content and pH on plant availability of both inorganic and organic selenium (Se) fertilisers. Further, the risk of Se leaching after application of inorganic Se fertiliser was evaluated. A new interpretation of an older field study at different sites in Southern Norway showed that organic C was correlated with grain Se concentration in wheat, barley and oats, explaining up to 60% of the variation in Se concentration. Pot experiments with a peat soil, a loam soil and a peat/ loam soil mixture were conducted for the present study at a range of pH values between pH 5 and 7. Below pH 6, Se uptake from added Se fertiliser was higher in the soil types with high organic matter content than in the loam. The opposite occurred at a soil pH above 6, where Se uptake was higher in the loam than in the peat soil. A simple leaching experiment after one growing season confirmed the findings of the pot experiments that Se availability in the loam soil with a relatively low organic matter content increased with increasing pH, whereas it decreased in the peat soil. Neither Se yeast, nor pure Se methionine, used as organic Se fertiliser, resulted in any significant uptake of Se when added at concentrations similar to the inorganic Se applications.

“…Several studies show that an increase in soil pH increases plant Se uptake (Cary and Allaway 1969;Lindberg and Bingefors 1970;Johnsson 1991). Redox conditions and pH have an important effect on Se availability since a combination of these factors determines the Se species present in a given soil environment.…”

“…Most of the selenium values found in this study were similar to those regarded as low in reports from other parts of the world, New Zealand (Davies & Watkinson, 1966), Sweden (Lindberg & Bingefors, 1970), Canada (Gupta & Winter, 1975) and Denmark (Mattsson, 1982). In the Agricultural Research Council (1980) review of the selenium contents of diets and forage in relation to selenium responsive conditions in animals it was concluded that values below 0-03 mg/kg were likely to be …”

The selenium concentration of cereal grain and herbage from 131 farms in England and Wales was, in general, low: the proportions of samples with values below 0-03 mg/ kg D.M. were 60 % for grain (primarily barley, from 96 farms) and 39 % for conserved herbage (primarily hay, from 131 farms). Values for fresh herbage from 12 farms were similar to those for conserved herbage. There were no significant differences in selenium concentration among herbage species. For all samples, those from the Cambridge area contained more selenium than those from other parts of England and Wales.

In pots containing sandy soils at two levels (pH 5 and 7) to which 0.5 mg Se L-t soil had been added, an increase in the proportion of clay soil or peat soil led to a decrease in the uptake of Se by spring wheat grain (Triticum aestivum L., var. Drabant) and winter rape plants (Brassica napus L., var. Emil). The effect was most pronounced for the smallest additions of clay and peat soils. Differences in Se uptake between the two pH levels were greatest in treatments where the additions of clay and peat soils were small. At the high pH, an increase in clay content from 7% to 39% resulted in a decrease in Se uptake of 79% for wheat and 70% for rape. At the low pH, the uptake decreased by 72% and 77%, respectively. At the higher pH, an increase in the content of organic matter from 1.4% to 39% resulted in decreases in Se uptake of 88% for wheat grain and 69% for rape. At the low pH, Se uptake decreased by 63% and 48%, respectively. Adding peat soil to clay soil had little effect on Se uptake. Among the limed, unmixed clay, sand and peat soils to which Se had not been added, uptake was highest from the sandy soil, i.e. 8.3 ng Se/g wheat grain and 42 ng Se/g rape. The lowest uptake rates were obtained in the clay soil, i.e. 3.0 ng Se/g for wheat grain and 9.0ng Se/g for rape.
