Dry, windy weather in Iowa helps dry crops, accelerates soybean harvest, USDA says; 27% of corn, nearly 50% of soybeans harvested
DES MOINES, Iowa
October 11, 2011
– Dry and windy weather accelerated crop dry down and provided the opportunity to harvest nearly half of Iowa’s soybean acres. Unfortunately, reports of soybeans shattering and field fires increased. The lack of moisture has also delayed development of fall seeded crops.
There were 6.8 days suitable for fieldwork statewide during the past week. Topsoil moisture levels rated 32 percent very short, 41 percent short, 27 percent adequate, and 0 percent surplus. Subsoil moisture rated 24 percent very short, 41 percent short, 34 percent adequate, and 1 percent surplus. With nearly the full week suitable for fieldwork, over half of the State is now seeing moderate to heavy grain movement from farm to elevator. At this point in the harvest season, only 3 percent of the State reports being short off-farm storage capacity and 7 percent of the State reports a shortage of on-farm storage capacity.
Ninety-seven percent of the corn crop is now mature, behind last year’s 99 percent but ahead of the normal 91 percent. Twenty-seven percent of the corn crop has been harvested for grain or seed, 3 days behind 2010 but 5 days ahead of the five-year average. The moisture content of the corn left to harvest throughout the State fell 4 percent from previous week to an average of 20 percent, with the corn currently being harvested running 18 percent moisture content. Corn lodging remains a greater problem than normal, with 21 percent of Iowa’s corn crop experiencing moderate to heavy lodging compared to 10 percent on average. Ten percent of the corn crop is experiencing moderate to heavy ear droppage compared to 5 percent normally. Corn condition stands at 5 percent very poor, 9 percent poor, 27 percent fair, 47 percent good, and 12 percent excellent. Ninety- seven percent of Iowa’s soybean fields are dropping leaves, equal to last year and 1 percentage point ahead of normal. Almost 50 percent of Iowa’s soybean crop was harvested last week, with soybean harvest jumping to 70 percent complete, still behind last year’s 74 percent but 5 days ahead of the average pace. Only two districts, East Central and South Central, have yet to reach 50 percent harvested for soybeans. Soybean shattering levels increased from the previous week to 16percent moderate to heavy. Soybean condition stands at 4 percent very poor, 8 percent poor, 23 percent fair, 47 percent good and 18 percent excellent.
Pasture and range condition rated 17 percent very poor, 23 percent poor, 34 percent fair, 22 percent good, and 4 percent excellent. Hay supplies are considered short in 19 percent of Iowa as many producers are already feeding hay as pasture growth is nonexistent due to dry conditions.
