Wet spring--good or bad? Above average snowfall and spring rains have replenished both topsoil and subsoil moisture across Iowa. This spring, Iowa's overall topsoil moisture is rated 4 percent short, 73 percent adequate, and 23 percent surplus. Subsoil moisture rated 5 percent very short, 22 percent short, 63 percent adequate, and 10 percent surplus, representing a substantial improvement over last fall's ratings, when nearly 90 percent was cited as short or very short. However, the amount of moisture received this season is a mixed blessing: it is needed but it also is delaying fieldwork.
