Abstract
In a pot experiment in 1973, 3 calcareous soils (25, 54 and 96% CaCO3, respectively) were mixed with sand or Nile silt in the proportions 2:1 and half the mixtures were inoculated with silicate-dissolving bacteria. Sudan grass was grown for 90 days in pots kept at 30 deg C and water holding capacity 50%. Despite higher counts of silicate-dissolving bacteria in inoculated treatments, K uptake was not significantly increased. Soils with 96% CaCO3 showed about twice the K uptake found in the other soils, irrespective of inoculation. The addition of Nile silt increased K uptake more than treatment by inoculation
