Return to the List of 2001 Crop Weather Reports

Released: September 10, 2001 -- 3:00 p.m. CST For Week Ending September 9, 2001 SD-CW3601 Volume 50 Issue 36

AGRICULTURAL SUMMARY:    Row crops continued in need of moisture to progress toward maturity, while livestock welcomed the change in weather at week's end, according to USDA's South Dakota Agricultural Statistics Service. Major farm activities for the week included cutting silage and preparing equipment for soybean and corn harvest. Statewide, there were 6.3 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:  Hot, dry, and windy conditions moderated to cool and cloudy with widely separated showers at week's end. Temperatures ranged from 1 to 10 degrees above normal. Highs in the upper 90's were common, with 22 stations between 100 and 108. Lows ranged from 30 in Custer to 50 in Sioux Falls. Precipitation was scarce, with only eight stations reporting over a half inch. The southeast and east central regions had the most rainfall.

SOIL CONDITION:   Another in a series of weeks with little to no rain has left most of the state too dry for crop development. Only 20 percent of the state was rated as having adequate topsoil moisture, an increase of 1 percentage point over a week earlier. Areas of the state rated as having very short topsoil moisture increased by 2 percentage points to 34. Subsoil moisture availability decreased 7 percentage points to 74 percent of the state reported as short or very short.

FIELD CROPS REPORT:    Hot, dry weather is pushing crop progress toward maturity, while crop conditions decrease as moisture stress takes its toll. Many reporters expressed concern over soybean pods filling. Soybeans are 42 percent dropping leaves and 12 percent mature, compared to last year's 38 percent dropping leaves and 14 percent mature. Corn reached 82 percent dented last week and 21 percent mature, compared to last year's 73 and 21 percent, respectively. Grain sorghum rated mature, at 22 percent, is just ahead of last year's 17 percent, while harvest started at 1 percent. Silage harvest continued, with sorghum silage 36 percent and corn silage 47 percent complete. Sunflower crop progress rated behind last year's pace, with 58 percent of the crop bracts yellowing, compared to 59 a year ago, while 8 percent is mature versus 14 last year. Topsoil moisture shortages are limiting the seeding of winter crops, with winter wheat and rye 10 and 9 percent seeded, compared to the five-year averages of 15 and 17 percent, respectively.

LIVESTOCK, PASTURE, AND RANGE REPORT:    Ranchers remain concerned as to how long they can pasture cattle on dry, browning range and pastures, with a few reporting that they have begun supplemental feeding. Range and pasture conditions continued to decline, with only 29 percent of the state in good to excellent condition, down 11 points from a week earlier. Feed and water supplies remain mostly adequate, however, one fourth of the state now has short or very short stock water supplies. Cattle and sheep remain mostly in good to excellent condition.
