Good roads are a “must” to the Iowa farmer. Once they are built, how can we keep them from going to pieces because of washing—erosion? A big portion of the answer to that question appears to be sowing the right plants with the right methods on roadsides, cuts and fills to make the soil stay “put.” Still more of the answer lies with the Iowa farmer, for his lands adjoining the highways if not properly farmed may help destroy the good roads he wants so badly.
