Abstract
The influence of lime and borax on the microbiol. activity of Norfolk fine sandy loam is reported. Measurements of amts. of CO2 evolved show that borax increased microbiol. activity at both pH 5.1 and pH 7.7. The influence of borax was greater at the higher reaction. Plate counts show that the fungus population was affected more by the addition of borax than was the population of bacteria. Growth of Trichoderma was confined almost entirely to the borax-treated soil. The possible use of Trichoderma species for a soil test of boron deficiency is suggested. The "fixation" of B in limed soils is apparently due, at least in part, to the increased activity of the soil microorganisms.
