Rye (Secale cereale L.) roots and shoots release C and N compounds in situ during their decomposition. Concentric layers of aggregates (2.0 – 4.0, 4.0 – 6.3 and 6.3 – 9.5 mm) were removed by newly designed meso soil aggregate erosion (SAE) chambers. Soil aggregate erosion rates were determined by recording the required time to remove external and transitional layers of aggregates. Soil aggregates sampled from rye cover cropped plots were more resistant to erodobility than those sampled from control plots. Rye roots contributed as much as rye shoots to the soil aggregate stability. Therefore maintaining active plant root in the soil can increase resistance of soil aggregates.
