mn-crop-weather State Minnesota Weekly Crop-Weather Week Ending Date Week Ending April 10, 2011 Issue MN-CW-14-11 Agricultural Summary A second round of flooding was underway in Minnesota rivers and tributaries, according to the USDA, NASS, Minnesota Field Office. This spring's flood threat was magnified by high moisture in the soil after back-to-back wet years and near record winter snowfall. The Red River crested Saturday night at Fargo-Moorhead, and flood waters have closed roads and submerged fields in localized areas. Secondary crests occurred elsewhere, with many rivers and their tributaries' in flood stage. A few reporters noted that soil is still too wet for fieldwork, and more warm, dry weather is needed to melt remaining frost, increase soil temperatures, and dry out soils before fieldwork can begin. Producers anticipated full scale fieldwork to begin on April 25, 4 days behind the five-year average. Topsoil moisture supplies were rated 46 percent adequate and 54 percent surplus, compared to 35 percent adequate and 65 percent surplus last week. One percent of land was prepared for corn and soybeans, behind last year but close to average pace. A warming trend caused the weekly average temperature to increase to nearly 5 degrees above normal. Temperatures ranged from the upper 40's in northern areas to 50's and 60's in central and southern areas. Readings reached over 70 degrees in some areas over the weekend, accompanied by showers and thunderstorms that hit late Saturday night and again Sunday evening over parts of Minnesota and western Wisconsin.
