SUMMARY Chlorella pyrenoidosa Chick (Indiana University Number 252 ), Nostoc commune Vaucher (I.U. 584), and Oscillatoria prolifica (Grev.) Gomont (I.U. 1270) were grown separately on Peoria loess soil material to measure their effects on the water stability of soil aggregates. Each alga significantly (10% LSD) increased the percentage of soil aggregates after 6 weeks of incubation as compared with the soil without algae. Oscillatoria, Chlorella , and Nostoc increased water stability of aggregates >74 μ in diameter by 3.4, 1.1, and 0.6% , respectively. Nostoc and Oscillatoria produced measurable water stable aggregates in the 1000–2000 μ diameter range ; Chlorella formed them in the 500–1000 μ range, while the control soil showed no aggregates >295 μ.
