Soil samples collected from 80 locations in Poland were analysed for numbers of root-nodule bacteria (rhizobia) fixing N2 in symbiosis with leguminous crops. Basic chemical and physical properties of the examined soils were also determined and correlation coefficients between these properties and numbers of rhizobia in the soils were calculated. Soil populations of alfalfa and clover rhizobia were significantly and positively correlated with soil pH and clay contents in the soils while negative correlation coefficients between these parameters and populations of lupine rhizobia were shown.
