Comparison of Different Pre-wetting Strategies in Wet Aggregate Stability Determination
Accurate determination of water-stable aggregates is of great significance for soil fertility
soilquality and soil erosion.Followed the three popular pre-wetting methods(no vacuum fast pre-wetting
novacuum fast dripping pre-wetting and no vacuum slow vapor pre-wetting)
the contents of water-stable aggregates of 5soil types(black soil
cinnamon soil
loess soil
purple soil and red soil)were measured.Basedon paired-sample t tests
the results showed that the measured contents were fairly stable with the samemethod but varied substantially with different methods.The method of no vacuum fast pre-wetting generatedthe lowest values
no vacuum fast dripping pre-wetting the moderate
and no vacuum slow vapor pre-wettingthe highest
which might be suitable respectively for the conditions of heavy rain storms
