Elemental composition of corn and soybean grown on fly ash amended soil

Abstract

Corn (Zea mays L.) and soybean (Glycine max L.) were grown on sandy loam alluvial soil amended with fly ash at rates ranging up to and including 25% by weight. Plant analysis data for 7 elements showed enhanced absorption of B, Cu, Mn and Zn with increasing rates of fly ash application. Phosphorus, potassium and calcium concentrations in the two crops were not affected by fly ash application.
