Synopsis Many Michigan soils are relatively low in B available to alfalfa during periods when surface soils are low in moisture content. The occurrence of deficiency symptoms indicates a low level of available B and a need for B fertilization. Test results of less than 20 ppm. B in the top 1 or 2 inches of alfalfa or less than 0.9 to 1.0 ppm. soil B extractable in boiling water also indicate a need for B fertilization.
