The hot temperatures are rapidly drying soils and moisture is needed in many parts of the state to aid row crop development. Topsoil moisture supplies rated 2 percent very short, 21 short, 67 adequate, and 10 surplus. Subsoil moisture supplies rated 1 percent very short, 13 short, 76 adequate, and 10 surplus. Corn silking was 5 percent, behind last years’ 38 and 12 average. Condition rated 2 percent very poor, 5 poor, 22 fair, 57 good, and 14 excellent. Soybean blooming was 26 percent, behind 2012 at 66 and average at 39. Condition rated 1 percent very poor, 3 poor, 22 fair, 61 good, and 13 excellent.
It rained a significant amount this week, impeding progress on harvesting of winter wheat and hay for most producers. There were reports throughout the State of flash flooding in fields. Most producers are waiting for drier weather to finish their first or second cutting of hay, as well. Soybeans and corn are still in good condition, but there are reports of spot damage to both crops from storms this week. Topsoil is rated 59 percent surplus and 40 percent adequate, with subsoil at 43 percent surplus and 55 percent adequate. Corn is rated 74 percent good to excellent with 19 percent silking. Soybeans are 67 percent good to excellent with 27 percent blooming.
Timely rain in most areas of the state and above normal temperatures improved crop development last week, however, portions of western South Dakota are in need of moisture. Topsoil moisture supplies rated 5 percent very short, 18 short, 70 adequate, and 7 surplus. Subsoil moisture supplies rated 8 percent very short, 20 short, 66 adequate, and 6 surplus. Corn silking was 6 percent, behind 34 last year but near 9 average. Condition rated 2 percent very poor, 3 poor, 20 fair, 56 good, and 19 excellent. Soybean blooming was 36 percent, behind last years’ 70 and 41 average. Condition rated 1 percent very poor, 4 poor, 24 fair, 54 good, and 17 excellent.
Though crops were still lagging behind normal development, reporters noted that corn growth exploded this week in response to the warmth. In spite of above normal precipitation this spring, corn was reportedly in need of rain in some areas. Delays to fieldwork and excessive moisture earlier in the growing season have reportedly caused wide variation in crop condition and progress. Corn was 44 inches tall on average, and 2 percent silking compared to the five year average of 14 percent. The corn is rated 77 percent good to excellent. Soybeans are 98 percent emerged and 13 percent are blooming with some late planting still underway. Soybeans are rated 66 percent good to excellent.
Except for the state of Ohio, crop reporters in all other Corn Belt states have comments about dry soils and the need for rain. While such needs are surprising in the wake of near record rainfall, the early rains did not promote deep root growth on corn and crops are much more subject to drought stress when topsoils dry out.
