title: Effect of sulfur application on sulfur-oxidizing bacteria and yield of two leguminous crops.
abstract: The effect of elemental sulfur application at the rate of 50, 100, 200, and 400 kg/feddan on broad-bean and lentil was tested in field experiments. Sulfur application resulted in increasing the numbers of the autotrophic sulfur-oxidizing bacteria as well as in the concentration of available sulfate in the soil; the increases were proportional to the level of sulfur added. The sulfur treatments neither affected the soil pH nor the nodulation of the leguminous plants tested. The application of sulfur at the rates used slightly increased seed yield and nitrogen content of lentil seeds, but had no effect on broadbean.
