This may require narrow, wide-spaced dual tires on combines. Planting up and down long, steep slopes may increase erosion compared to other systems, especially no-till. High management is required to make the system work. Placement and incorporation of fertilizer, herbicides, and pesticides will usually change from previous procedures. Rows should be carefully laid out the year ridges are built.
End rows present a problem.
Winter annuals may cause a problem with ridge-till. They usually are spotted over the field but may require control with preplant herbicides to prevent moisture loss. Even then, some growers observe stunted plants and slow growth, perhaps due to an allelopathic effect. Copyright 1999 University of Missouri.
