Potential for wind erosion as affected by management in bean-potato rotations

dc.description.abstractThe potential for soil erosion in the bean phase of bean-potato rotations is significant due to low levels of crop residue following potatoes and the effect of management on soil structure particularly in light textured soils typical of the potato growing area of Manitoba. This potential can be mitigated by fall cover crops, application of straw or composted manure. In a study at Carberry, MB crop residue cover from 2000 to 2004, the proportion of small erodible aggregates and stability of aggregates were measured in treatments with fall applied cereal, fall applied compost, and spring applied polymer. Crop residue cover, proportion of erodible aggregates and aggregate stability were not consistently affected by management over the short term. In some years application of cereal residue in the fall increased residue cover, reduced the proportion of small erodible aggregates (<0.5 mm) and increased stability of aggregates. Application of polyacrylamide did not affect stability of wet-sieved aggregates but decreased the proportion of small aggregates (<0.5 mm) in 2002. Further research is required to assess the long-term impact of management on potential for wind erosion and properties of soil aggregates in bean-potato rotations.en_US
