In the 1930s or 1940s, corn planting disturbed the soil far more than no-till corn planting did in the 2010s. A wheat threshing machine separated the wheat berry from the plant, and cut wheat was hauled from neighboring fields to the machine because it could not be easily moved. A combination machine, or combine, cuts the plant off and then separates the wheat berry, while a grain cart drives alongside to gather harvested grain for loading onto a truck so the combine does not have to stop to unload. Feed for livestock was once cut and piled in stacks, with horses powering the cutter, and modern hay balers turn piled hay into easily stackable and transportable round hay bales. Horse-drawn discs worked the earth, and in one scene local farmers helped a neighbor facing illness or a loss who otherwise would have been unable to plant in time for a bountiful harvest. Spraying weeds instead of turning up the earth promotes soil conservation and preserves moisture.
