Abstract

Two laboratory-prepared ferric hydroxy bi-selenites and
CuSeO₃ applied to Portneuf silt ham in the field provided
slowly available Se to alfalfa, resulting in Se concentration adequate
but nontoxic for livestock. These materials have potential
as Se fertilizers at low application rates. The ferric hydroxy
bi-selenites offer little or no advantage over CuSeO₃. Se from
BaSeO₄ alone, BaSeO₄—BaSO₄ mixtures, and CuSeO₄ was
absorbed by alfalfa in concentrations toxic to livestock. A small
fraction of applied elemental Se was available immediately
after application, providing adequate Se to alfalfa for livestock.
The remaining elemental Se was rather inert, and supplies only
slightly more Se to alfalfa than did the untreated soil the year
following application.
