Abstract
Repeated sampling at a single location on each of three soil types at irregular intervals during the 12-year period 1955–1967 indicated a highly monthly and yearly variation in the percentage of the total soil in aggregates < 0.84 mm in diameter (the erodible fraction) by dry-sieve analysis. The greatest degree of variation occurred in the clay soil. Increases and decreases in aggregation were correlated among soils.The amount of the erodible fraction determined by dry-sieve analysis is highly dependent on the date of sampling. Consequently, the value of dry sieving as a method of predicting the susceptibility of soils to wind erosion over an extended period of time is limited.This publication has 1 reference indexed in Scilit:
