We took samples of six surface soils, two subsurface soils, and one organic soil from the Menomonee River Watershed, Wisconsin, and dispersed them by (1) shaking with water to simulate natural water erosion and particle transport conditions, and (2) ultrasound to provide complete dispersion. The...
Biochar is widely recognized as an amendment that enhances soil properties and sequesters carbon, particularly in degraded soils. However, biochar applied
The testing method for the 18 soil profiles generally identified fewer horizons than in the field. The master horizons were mostly identified with both color systems (except the CM3 and CM4 soil profiles) because the A and B horizons of these profiles are morphologically homogeneous in terms of ...
