mn-crop-weather State Minnesota Weekly Crop-Weather Week Ending Date Week Ending June 20, 2010 Issue MN-CW-24-10 Agricultural Summary Severe storms during the week brought heavy rains, damaging winds, and dozens of tornadoes across the state according to the USDA, NASS, Minnesota Field Office. As of June 20, statewide average precipitation was 1.1 inches which produced standing water in some areas and delayed herbicide application. Producers, faced with only brief periods of sun and warm temperatures throughout the month of June, reported a need for warmer, drier weather. Statewide, 2.6 days were rated suitable for fieldwork. Topsoil moisture supplies were rated 99 percent in adequate to surplus condition. Wet conditions have impacted haying and caused some producers, particularly in northern areas, to chop the alfalfa first cutting back onto the fields. Saturated fields prevented producers from harvesting the remaining crop. Widespread incidents of alfalfa weevil were reported with delayed spraying due to frequent rains. Alfalfa cutting advanced only 2 percentage points from the previous week and was rated 81 percent in good to excellent condition, compared to 87 percent during the previous week. Corn was rated 93 percent in good to excellent condition with an average height of 21 inches, while soybean condition was rated 89 percent in good to excellent condition with a height of 6 inches. Small grain development continued ahead of average. Fifty percent of spring wheat and 57 percent of barley were heading, while 64 percent of oats were heading and one percent was ripening. Dry beans were 99 percent planted while sweet corn was 91 percent planted. Pasture conditions were rated 1 percent poor, 13 percent fair, 63 percent good, and 23 percent excellent.
