Rice production in the subtropical climate of Florida is on Histosols, which are high in organic matter content and low in plant-available silicon (SI). broadcast rates of calcium silicate slag were 0, 5, 10, and 15 Mg/ha in 1987 and 1988. In 1987, applications of calcium silicate slag reduced blast by 30.5% and brown spot by 15.0% over the control. In 1988, blast and brown spot were reduced by 17.4 and 32.4%, respectively, over the control (...)
