Iowa Draws Down Corn Condition Ratings

June 10, 2013 10:40 AM

Below we use USDA's weekly crop condition ratings to calculate our weighted (by production) Pro Farmer Crop Condition Index (CCI; 0 to 500 point scale). The Pro Farmer CCI for the corn crop declined more than 8 points from last week, and the crop now stands 5.59 points below last year at this time. Much of the decline can be chalked up to a more than 7-point decline in the No. 1 corn producting state of Iowa.

Iowa: Rainfall continued to limit fieldwork for Iowa farmers during the week ending June 9, 2013, according to the USDA, NASS. Fields already wet from the previous week, did not dry enough between rain events to allow significant planting progress to be made. Farmers commented warmth and sun would benefit the growing corn and soybean crops. Statewide there were an average of 1.7 days suitable for fieldwork during the week. East Central Iowa, with 2.5, had the most days suitable for fieldwork during the week. North Central Iowa, with 0.9, had the least days suitable. Topsoil moisture levels rated 0% very short, 0% short, 42% adequate and 58% surplus. Subsoil moisture levels rated 0% very short, 2% short, 60% adequate and 38% surplus. The surplus subsoil rating is the highest since August 2010.

Ninety-two percent of Iowa's corn crop was in the ground, 4 percentage points higher than last week, and still lagging behind the five-year average of 99%. Eighty-one percent of the corn crop has emerged, behind the normal 96%. Corn condition was reported at 3% very poor, 11% poor, 34% fair, 44% good and 8% excellent.

Farmers have planted 60% of the soybean crop, an advancement of 16 percentage points from last week, but still much lower than the normal 95%. Soybean emergence was 39% complete; well behind both last year's 93%, and the five-year average of 83%. Both the planting and emergence for soybeans were the latest since 1993.

Illinois: Farmers found small windows of time to plant corn and soybeans and a few had dry enough conditions to bale hay. Isolated rain showers fell over the state this past week, heavier rains being in the Northwest, though nothing significant throughout most of the state. Some of those that have planted in previous weeks have found their corn to be emerging unevenly, so there will be some replanting. For the most part, everyone is hoping for even drier conditions over the next week to finish planting corn and soybeans. Temperatures across the state averaged 64.6 degrees for the week, 4.6 degrees below normal. There were only 3.40 days suitable for field work last week. Topsoil moisture levels across the state were rated as 64% adequate and 36% surplus.

Corn planting was 96% complete, compared the five-year average of 98%. Corn emerged progressed to 89% compared to 100% last year and the five-year average of 92%. Corn conditions were rated at 3% very poor, 10% poor, 29% fair, 47% good, and 11% excellent.

Soybean planting was accelerated by weather conditions this week and progressed to 62% complete. Winter wheat conditions were rated as 4% poor, 28% fair, 57% good, and 11% excellent.

Nebraska: For the week ending June 9, 2013, drier conditions allowed producers time to accomplish fieldwork ranging from planting to bailing hay and applying chemicals, according to USDA's NASS, Nebraska Field Office. Soybean planting is nearly complete.

Temperatures ranged from 2 to 8 degrees below normal across the state with portions of eastern and central Nebraska receiving up to an inch of rain. Statewide, producers had 5.3 days suitable for fieldwork. Topsoil moisture supplies rated 6% very short, 21% short, 69% adequate, and 4% surplus. Subsoil moisture supplies rated 23% very short, 35% short, 41% adequate and 1% surplus.

Corn conditions rated 0% very poor, 2% poor, 23% fair, 65% good, 10% excellent. The crop was 91% emerged, behind last year's 100% and 97% average. Soybean conditions rated 0% very poor, 2% poor, 23% fair, 67% good, 8% excellent. Soybeans were 94% planted, behind last year's 100% and same as 94% average. Emerged was 71%, well behind last year's 96% and 81% average.

Minnesota: Wet conditions in Minnesota continued to hamper field work for the week ending June 9, 2013 according to the USDA, NASS. There were just 2.6 days rated suitable for fieldwork statewide. Statewide average temperatures were 6.6 degrees below normal. The Central District showed the greatest deviation from normal temperatures at 8.1 degrees below normal. Topsoil moisture supplies increased to 0% very short, 1% short, 60% adequate, and 39% surplus. Subsoil moisture supplies also increased to 1% very short, 7% short, 70% adequate and 22% surplus.

Corn planting only advanced 3 percentage points to 90%, remaining behind last year's 100% and the five year average of 99%. Corn emergence increased 13 percentage points to 78%, remaining behind last year's 100% and the average of 95%. The statewide average corn height was 3 inches tall, compared to 13 inches last year, and the average of 7 inches. Corn condition decreased to 2% very poor, 6% poor, 37% fair, 50% good, and 5% excellent.

Despite the wet conditions, soybean planting advanced 17 percentage points to 72% planted, behind last year's 99% and the average of 95%. Soybean emergence also moved along to 38% emerged, compared with last week's 18%, last year's 92% and the average of 78%.

Indiana: Cool, dry days across the central and northern districts allowed farmers to resume field work as soils dried out from the previous week’s heavy rainfall, according to the Indiana Field Office of USDA’s NASS. Some of the southern counties did receive rain which put planting even further behind. Many operations were busy planting soybeans, side dressing corn and spraying post emergence herbicides.

There were 4.5 days suitable for field work during the week. Ninety-eight percent of the intended corn acreage has been planted at this time compared with 100% last year and 95% for the five-year average. Planting is nearly finished in the northern and central areas and is 91% complete in the south. Ninety percent of the corn acreage has emerged compared with 100% last year and 85% for the five-year average.

Eighty-seven percent of the intended soybean acreage has been planted compared with 99% last year and 79% for the five-year average. By area, 96% of the soybean acreage has been planted in the north, 92% in the central region and 60% in the south. Seventy percent of the soybean acreage has emerged compared with 93% last year and 62% for the five-year average.

South Dakota: For the week ending June 9, 2013, wet and cool conditions continued again this week limiting fieldwork, according to the USDA's NASS, South Dakota Field Office. Statewide, there were 4.2 days suitable for fieldwork. The cool conditions also slowed crop growth and development. Topsoil moisture supplies rated 0% very short, 5 short, 79 adequate, and 16 surplus. Subsoil moisture supplies rated 2% very short, 20 short, 73 adequate, and 5 surplus. Major farm activities included spraying for weeds and fertilizer applications.

Ohio: There were five days suitable for fieldwork in Ohio during the week ending June 9, according to the USDA, NASS, Great Lakes Region. Producers took advantage of the continued warm weather and completed the planting of corn and oats, and neared completion of soybean planting. Some producers also replanted crops lost due to frost. Nitrogen application to corn also moved quickly, with some counties reporting that it was nearly finished.
