Abstract

Forest, Miller and Raizen (1963) and Hutcheson and Olson (1967) have conducted two of the only investigations on soil algae in a prairie ecosystem. The present investigation dealt first with identification of genera of algae present in the soil and an evaluation of their numbers. Secondarily a relationship was established between the numbers of algae in the soil (by species) and their environment, by the correlation coefficients. The variation in the environment was then used to predict the occurrence of algae in the soil using stepwise additive multiple regression analysis. Finally several environmental factors were evaluated under controlled conditions to determine their effect on soil algal growth. Changes in Algal biomass were determined spectrophotometrically from chlorophyll extraction.
