The farm lies on the Illinoian Glacial Till with soil types of Cincinnati, Edenton, Rossmoyne, Hickory, Genesee, Avonburg and Clermont. Top soil depth 7 inches over several feet of dense to loamy subsoils. Slopes range from 0-20%, acid topsoil and subsoil, highly weathered, organic matter averages one percent.

100 acres of corn was raised each year on this farm for over 100 years with 2 horses plowing, planting, cultivating, and pulling the corn shucking sled. A Farmall Regular was added for disking in the 1920's. George and son Gerald did most of the work. Then Gerald's sons Ed and Jeff helped until Grandson's Matt and Mark started helping in the 1990's.

The first new tractor was implemented by Gerald in 1949, months before Ed was born and was used for plowing and disking and haymaking. It was traded for an Oliver Super 77 in 1957 with 3 bottom 3 point hitch plow, disk, planter and cultivator. The Super 77 was traded for an Oliver 770 in the 1960's and it took over the old tasks. Meanwhile a Ford 8N was replaced by an Oliver 550, which was used for many years. An Oliver 1265 replaced it and is still on the farm with over 10,000 hours on it. Other tractors since include an Oliver 1850, 1755, 1955(still on the farm), White2-70 and now an Allis Chalmers 160.

Most of the corn planted in 1970 was N cytoplasm and the corn blight did not affect the farm like it did the neighbor's corn. In the mid sixties, 160 bushels was broken for the first time and in 1971 226 bushels per acre was produced on one field which destroyed the Oliver Number 4, 2 row mounted picker. In 1994, 240 bushels was broken but there have been more 100 bushel years than 200.
