Indiana: Rain showers helped to improve drought conditions with less than half the state still in extreme to exceptional drought conditions compared with nearly 70% on July 31, according to the Indiana Field Office of USDA's National Agricultural Statistics Service. Corn harvest has begun in a few scattered fields around the state. Pastures and hay fields have greened up considerably in the last two weeks with hopes of one more cutting of hay before the end of the season. Later planted soybeans are benefitting from the recent rainfall with additional growth and pod fill. The rains have also slowed spider mite activity and hopefully will help limit the amount of aflatoxin in the corn crop. Lower than normal silage yields are being reported in drought damaged corn due to reduced stalk matter.

There were 5.3 days suitable for field work during the week. Ninety-one percent of the corn acreage is in dough compared with 64% last year and 69% for the 5-year average. Fifty-eight percent of the corn is in the dent stage compared to 17% last year and 25% for the 5-year average. Nine percent of the corn acreage is mature compared to 0% last year and 1% for the 5-year average. Corn condition is rated 9% good to excellent compared with 38% last year at this time.

Corn progress continued ahead of the five-year average pace. Corn was 92% in the dough stage or beyond, compared to 46% average. Fifty percent of corn was in the dent stage, compared to 15% average. Corn condition was rated 77% fair to good, unchanged from the previous week. Corn harvested for silage was 16% complete, compared to 4% average.

Soybeans were rated 81% in fair to good condition, compared to 80% the previous week.

South Dakota: There were 6.6 days suitable for field work this past week. The temperature transition from very warm conditions has continued with statewide temperatures being much below average for the week, according to the State Climate Office of South Dakota. Several low temperature records were tied or set at stations around the state. Precipitation was limited across the state. Thus, changes in the state's drought status were minimal. Precipitation was also limited with no stations reporting over an inch. Many stations had no or very little precipitation. Sioux Falls had the highest total at 0.83 inches. Seven stations reported no precipitation. Another 16 had totals less than 0.10 inches. Thus, nearly the whole state was below average for the week continuing the summer dry trend. Lower temperatures have helped on some stress issues. But limited water and feed for cattle are continuing impacts.

Topsoil moisture was rated at 51% very short, 30% short and 19% adequate; a slight improvement from the previous week's estimate of 13% adequate. Subsoil moisture was rated at 56% very short, 27% short and 17% adequate to surplus.

Corn progressed this past week with 84% of the crop in the dough stage and 44% dented, steadily advancing from the 22% dented the previous week. Both stages are well ahead of the five year averages of 52% for the dough stage and 13% dented. Forty-eight percent of the corn crop has been cut for silage; ahead of both the previous year and five year averages of 2%. Soybeans setting pods were at 93% with 10% dropping leaves.
