Return to the List of 2005 CROP WEATHER Reports

Released: September 12, 2005 -- 3:00 pm CST For Week Ending September 11, 2005 SD-CW3705 Volume 54 Issue 37

AGRICULTURAL SUMMARY:   Temperatures averaged 12 degrees above normal for the state last week, further stressing crop conditions and soil moisture levels. Spotty rains throughout the week may have caused some delays in fieldwork, but it also made conditions ideal in some areas for the seeding of winter wheat. Major farm activities included seeding winter wheat, silage harvest, cutting alfalfa, moving hay and grain, preparing for fall harvest, and caring for livestock. Statewide, there were 5.8 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 12 degrees above normal for the state last week, with averages mostly in the 70's. The high for the week was 102 degrees, reported in Philip and Pierre. Bison reported the low for the week, at 45 degrees. Precipitation was scattered throughout the state, with Brookings reporting the most rain, at 4.21 inches.

SOIL CONDITION:   Despite last week's hot temperatures, topsoil and subsoil moisture levels improved. Topsoil moisture, while rated at 38 percent adequate to surplus the previous week, rose to 45 percent adequate to surplus last week. Subsoil moisture levels rose from 39 percent adequate to surplus the previous week, to 44 percent adequate to surplus last week.

FIELD CROPS REPORT:   Significant advancements were made in winter wheat seeding last week, jumping from 15 percent seeded the previous week to 29 percent seeded last week, with 1 percent of the crop emerged. Many producers commented that recent rains may be too late to benefit row crop development, but they should be beneficial to the winter wheat crop. Corn development remains ahead of last year's progress, with 92 percent in the dent stage and 21 percent of the crop rated mature. Corn silage harvest is ahead of both last year and the five-year average, with 50 percent harvested. Soybeans are rated 58 percent in good to excellent condition, with 62 percent of the crop dropping leaves and 12 percent rated mature; both ahead of last year's 37 percent and 4 percent, respectively. The sorghum crop is 83 percent coloring, with 15 percent rated mature. Sorghum silage harvest is well ahead of last year and the five-year average, with harvest 58 percent complete. Sunflower development remains ahead of last year, with 84 percent of the crop having ray flowers dry, 65 percent having bracts yellow, and 5 percent rated mature.

LIVESTOCK, PASTURE, AND RANGE REPORT:   Last week's hot weather caused range and pasture conditions to further deteriorate, with only 42 percent rated in good to excellent condition. Livestock remain in mostly good to excellent condition. Stock water supplies remain similar to the previous week, with a rating of 58 percent adequate to surplus. Alfalfa harvest continues with the third cutting 72 percent compete. Alfalfa condition is rated at 43 percent good to excellent.
