Soil Fertility and Farm Yields Highlighted by Wisconsin Expert
University of Wisconsin soil professor Emil Truog says high yields per acre come from better soil fertility and efficient use of seed and tillage. Tests show extra production from heavy fertilization costs only a few cents per unit, with legumes offsetting some losses through nitrogen. Proper liming and erosion control enable more land to be returned to forests and permanent pastures, boosting overall food supply.

Mechanized Hog Farm Boosts Pig Production
Dr. Waldo Semon of B F Goodrich describes a modern hog farm operated by a single worker handling 100 sows and producing 1,500 to 2,000 hogs per year. Conveyor belts chutes and rubber-tired tractors cut pulling power by half versus steel wheels, speeding plowing and saving fuel.

Deep Litter Enhances Dry Laying Houses This Winter
Iowa State College says deep litter keeps laying houses dry and well insulated and ventilated this winter. It develops heat as it slowly decomposes, helping flock health and reducing cleaning frequency as litter and droppings stay dry.
