The relationships between fly ash application to soil and B availability under field conditions were studied over a 3‐year period. The two fly ash samples studied contained 232 and 370 ppm of total B. Incorporation of one application in 1971 of either fly ash sample into a Tatum silt loam increased alfalfa ( Medicago sativa L.) yield over a 3‐year period. Yield increases were attributed to an alleviation of B deficiency. Boron uptake data indicated that B in the fly ash samples was readily available initially but decreased with time. Results of correlation and regression analyses suggested that hot‐water‐soluble B extractions could be used to predict plant availability of B in fly ash‐soil mixtures.
