Some areas of Iowa have experienced hard, late-spring rains that have contributed to various types of soil erosion, especially fields with minimum residue coverage, where sheet and rill erosions were observed. Erosion in unprotected soil can begin as soon as the first raindrops fall. With nothing to cushion the impact, raindrops can dislodge soil particles, splashing them up to several feet away.
