Return to the List of 2005 CROP WEATHER Reports

Released: May 2, 2005 -- 3:00 pm CST For Week Ending May 1, 2005 SD-CW1805 Volume 54 Issue 18

AGRICULTURAL SUMMARY:    While last week's weather brought temperatures that were well below normal for the state, producers were still able to make significant advancements in small grain seeding as well as corn planting, according to USDA's South Dakota Agricultural Statistics Service. Several producers have reported that crop development may have been slowed due to the cold weather, with some damage being done to alfalfa, grass, and perhaps even small grains due to the below-freezing temperatures received overnight in several areas. Major farm activities included machinery repair and maintenance in preparation for planting row crops, spring tillage, seeding small grains, fertilizing, fixing fence, and tending to livestock. Statewide there were 5.6 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 last week ranged from 14 degrees in Custer to 71 degrees in Newell. Average temperatures were in the upper 30's and lower 40's for the state, approximately 13 degrees below normal for this time of the year. Precipitation was scattered, with only 19 of the 43 reporting weather stations receiving precipitation. Hot Springs received the most precipitation last week, with 0.32 inch reported.

SOIL CONDITION:    With minimal precipitation received across the state last week, topsoil and subsoil moisture levels varied slightly from the previous week. Topsoil moisture fell from 81 percent adequate to surplus the previous week, to 74 percent adequate to surplus last week. Subsoil moisture levels rose slightly from 62 percent adequate to surplus the previous week to 64 percent adequate to surplus last week. Soil temperatures from reporting stations averaged about 1 degree below normal, with the average soil temperature of reporting stations at 45.6 degrees.

FIELD CROPS REPORT:    Last week's cool temperatures did little to keep farmers out of the fields, with the progress of small grain seeding advancing to levels similar to last year. Barley seeding is rated at 83 percent complete and 32 percent emerged, close to last year's progress of 85 percent seeded and 34 percent emerged. Oats seeding and emergence are also similar to last year, with ratings at 87 percent and 46 percent, respectively. Spring wheat seeding is 95 percent complete, with emergence at 60 percent, well ahead of the five-year average emergence rate of 39 percent. Corn planting advanced significantly last week, with planting 24 percent complete, still behind last year's rating of 29 percent planted, but ahead of the five-year average of 21 percent. Planting of soybeans has begun with planting 1 percent complete for the state, slightly behind last year's rating of 2 percent. Sorghum planting has also started, with the crop 1 percent planted. Winter wheat development has advanced to 18 percent in the boot stage, well ahead of last year's 2 percent and the five-year average of 4 percent. Winter wheat is currently rated at 80 percent in good to excellent condition.

LIVESTOCK, PASTURE, AND RANGE REPORT:    Cold weather last week did little to improve range and pasture conditions, with ratings falling to 33 percent in good to excellent condition. Below-freezing temperatures across the state may have damaged grass and delayed growth, which in turn has postponed the movement of cattle, with only 23 percent of cattle moved to pasture. Stock water supplies have remained fairly similar to the previous week, at 55 percent adequate to surplus. Livestock conditions are similar to the previous week, with cattle 86 percent in good to excellent condition and sheep 82 percent in good to excellent condition. Calving and lambing are both in line with the five-year average, with calving 82 percent complete and lambing 84 percent complete. Calf and sheep and lamb deaths remain mostly at or below average rates.
