Return to the List of 2005 CROP WEATHER Reports

Released: September 06, 2005 -- 3:00 pm CST For Week Ending September 04, 2005 SD-CW3605 Volume 54 Issue 36

AGRICULTURAL SUMMARY:   Last week's above-normal temperatures and minimal precipitation not only caused soil moisture levels to decline, but also deterioration of crop and range and pasture conditions. Significant advancements were made; however, in winter wheat seeding, silage harvest, and the cutting of third crop alfalfa. Other major farm activities included moving hay, irrigating, preparing for row crop harvest, and caring for livestock. Statewide, there were 6.5 days reported suitable for fieldwork. This report is based on information from county extension educators, Farm Service Agency county directors, and other reporters across the state.

WEATHER INFORMATION:   Temperatures averaged almost 6 degrees above normal for the state last week, with averages in the upper 60's and 70's. Both Milesville and Philip reported the high for the week of 105 degrees, while Porcupine reported the low, at 37 degrees. Precipitation was reported at only 11 of the 43 reporting weather stations last week. Sisseton reported the most rain, at 0.92 inch.

SOIL CONDITION:   With much of the state receiving little to no precipitation last week, topsoil and subsoil moisture levels continued to feel the stress. Topsoil moisture levels fell from 51 percent adequate to surplus the previous week, to only 38 percent adequate to surplus last week. Subsoil moisture levels fell from 50 percent adequate to surplus the previous week to 39 percent adequate to surplus last week, well below last year's rating of 46 percent adequate to surplus.

FIELD CROPS REPORT:   Row crop conditions declined last week, with much of the state receiving little or no precipitation. Corn condition fell to 52 percent rated good to excellent, with 96 percent of the crop in the dough stage. The corn crop is 72 percent in the dent stage, well ahead of the five-year average of 57 percent; while 6 percent is rated mature, behind the five-year average of 11 percent. Corn silage harvest advanced ahead of last year, with 34 percent harvested. Soybean condition fell from 62 percent good to excellent the previous week, to 53 percent good to excellent last week. Soybean development remains behind normal, with 30 percent having dropping leaves and 1 percent mature, compared to the five-year averages of 32 percent and 4 percent, respectively. Sorghum development remains behind average as well, with 61 percent coloring and 4 percent mature, behind the five-year averages of 67 percent and 8 percent, respectively. Sorghum silage harvest, however, is ahead of both last year and the five- year average, with 39 percent harvested. Sunflower development is ahead of last year, yet behind the five-year average, with 61 percent having ray flowers dry, 31 percent having bracts yellow, and 1 percent rated mature.

LIVESTOCK, PASTURE, AND RANGE REPORT:   Last week's hot and dry weather continued to stress range and pasture conditions, with ratings falling from 50 percent good to excellent the previous week, to 45 percent good to excellent last week. Cattle and sheep remain in mostly good to excellent condition. Dry weather caused stock water supplies to fall 6 percentage points, with the rating currently at 58 percent adequate to surplus. The third cutting of alfalfa advanced to 64 percent complete, with 46 percent of the alfalfa hay crop rated in good to excellent condition.
