Response of Alfalfa to Boron in Flyash1

Abstract

Abstract

The availability of B in flyash obtained from three coalburning power plants was evaluated by greenhouse and laboratory procedures. The samples of flyash contained 319, 415, and 618 ppm B and neutralized 0.12, 0.58, and 3.05 meq H3O+/g, respectively. Boron in the samples of flyash was readily available to alfalfa (Medicago sativa L). grown on Tatum silt loam. Yield and B uptake data indicated approximately equal availability of B in flyash, 1N HCl extracts of flyash, and Na2B4O7 · 10H2O. Application of high rates of the flyash sample having the highest neutralizing power decreased yield of alfalfa. The decrease in yield was attributed to Zn deficiency of alfalfa plants induced by the increase in soil pH resulting from application of the by-product.
