Abstract

A study was conducted to determine the effect of P fertilization
on the Se concentration in alfalfa. Adding P to the soil increased
the Se concentration in alfalfa grown in the greenhouse
on six of 14 soils from the northwestern United States. The Se
concentration increase in alfalfa resulting from P addition was
noted on some alkaline and some acid soils. Phosphorus addition
increased the availability to alfalfa of both native and
applied Se in the Portneuf silt loam. Applying 160 kg P/ha
either as H₃PO₄ or concentrated superphosphate to Gooding
sandy loam in the field increased the Se concentration in alfalfa
from a level marginal for animal requirements to an adequate
level.
