Sodium selenite, sodium selenate, and sodium selenate in a prill formulation were applied to three soils known to produce Se-deficient herbage (< 100-mu-g Se kg-1 dry matter (DM)). The ability of the salts, applied in spring 1985, to ameliorate Se deficiency was followed over 3 years by taking four harvests each year. Selenate treatment at 10 g Se ha-1 and selenate prill treatment at 20 g Se ha-1 produced herbage with Se levels (geometric means) of between 0.57-0.86 and 1-79 1.92 mg kg-1 DM respectively in the first spring harvest after treatment. Selenite was less potent and selenite at 100 g Se ha-1 produced a response in herbage closely similar to that of selenate at 10 g Se ha-1. Even at 300 g Se ha-1 the selenite treatment produced herbage with only 1.00-1.36 mg Se kg-1 DM at the first harvest. Application of selenate in the prill form at 60 g Se ha-1 produced herbage potentially toxic to grazing animals with 4.81-4.94 mg Se kg-1 DM. The addition of fertiliser N to Se-treated plots increased total Se uptake at the first harvest by a factor of 4 and had a small effect on Se concentration. The Se concentration levels in herbage from Se-treated plots declined exponentially (t1/2 = 21-43 days). On one soil derived from Lower Old Red Sandstone and lava, selenite at 300 g Se ha-1 gave herbage with Se contents significantly above background (P < 0.05) in all harvests over 3 years.
