Tests Of Grain Aeration To Cool And Dry Combine-Harvested Wheat By F. L. Fenton, C. O. Swanson, And Orval C. French At Kansas State University In 1930-31 Showed Mechanical Ventilation To Be More Effective Than Natural Draft Ventilation. Mechanical Aeration Was Further Developed In The 1940's To Prevent Moisture Migration, Which Caused Wetting And Spoilage Of The Top Layers Of Stored Grain. Studies In 1944-45 By Usda Agricultural Engineers G. W. French And W. V. Hukill Cooperating With Iowa State University Proved That Mechanical Aeration Prevented Moisture Migration. G. H.

Farm And Residence of John Johnston 1791 - 1880 Eminent Farmer Who Here Originated Tile Underdrainage in America in 1835 and Thereby Became an Outstanding Contributor to Human Welfare Honored by The American Society of Agricultural Engineers 1935. Erected by State Education Department
Established in 1907, the American Society of Agricultural Engineers (ASAE) was managed by volunteers. In 1925, local editor Raymond Olney was named secretary, thus establishing ASAE in this area. By 1969, with over 7,000 members in 100 countries, an ASAE building was constructed at this site in St. Joseph, Mi. In 2005, ASAE became ASABE to recognize the importance of biology in the profession. ASABE collects and maintains the unique body of knowledge for the agricultural/biological engineering profession.
