1943 “Farm Forum” hosted by Goodyear at Litchfield Park, Arizona, b&w, about 20 minutes.

From an Internet article:

In the 1920s many changes took place for the Goodyear Tire & Rubber Company in Arizona. The Southwest Cotton Company, a subsidiary of Goodyear, was in Arizona to plant cotton for their pneumatic tire cord and had several thousand acres under cultivation. In the early 1920s the price of cotton fell and then the 1929 Depression and Stock market crash changed the scenario of the Southwest Cotton Company. Many changes took place on the Litchfield Ranch after cotton was no longer needed for Goodyear tires. Rayon, a textile fiber, was introduced in the early 1930s as a tire cord and in the late 1930s steel belted radial tires were introduced. One of the largest farms all in one location in Arizona the Southwest Cotton Company had more than 16,000 acres with 12,000 acres of cultivated land. It was highly mechanized with 65 tractors and 52 trucks and automobiles plus scores of farm implements. The farms were very successful and in 1943 the name was changed to Goodyear Farms. The Goodyear Farms hosted a Farm Forum and invited people from several areas of farming to show the advances in farming. The Forum included farm implement manufacturers and their technical staffs, farm magazine editors and agricultural college professors. Many of the Goodyear executives also attended.

Crop rotation methods were implemented to replenish the soil and utilize the land when cotton was out of season. Scientific feed for cattle was produced and was a major use of the land. Other special activities started such as Tire & Farm Equipment Testing and the Apprentice Farmer program. An evolution of farming methods and techniques were underway at this time. The Southwest Cotton Company served as an agriculture laboratory in the trial and development of new types of farm equipment.
