Pot experiments were conducted to determine the effect of nitrogen forms on the absorption of bromide added as NaBr by sorghum. Plants supplied with NH4-N absorbed a greater amount of bromide than those with NO3-N while plants with a combination of NH4-N and NO3-N (1:1 ratio) were intermediate. There was a linear relationship between the amount of bromide applied and that absorbed by sorghum. The recovery of bromide in plant tops amounted to two-thirds of the bromide applied. Soil fumigation with D-D coupled widi N-Serve effectively inhibited nitrification of NH4-N fertilizer applied to soil. Such technique may be useful in studies where the effect of NH4-N versus NOs-N on plant nutrition is to be compared.
