Compactibility of certain soils as related to organic matter and erosion

Data on compactibility of certain soils in New York State have been presented and discussed. Within each of the flour soil series represented in the study, comparisons were made of compaction-moisture curves for samples differing in the amount of organic matter they contained. The samples containing the most organic matter were compacted to a lesser degree by a given compactive effort at a given soil moisture content. Furthermore, the moisture content at which maximum compaction occurred was higher. For three of the four series studied, the differences in organic matter were directly related to the extent of past erosion--either measured or observed. The data were discussed from the standpoint of practical application, and also from the standpoint of possible significance in the formation of surface crusts on the soil.
