Detailed explanation-1: -The second half of the 19th century saw some increase in land under cultivation and agricultural production expanded at an average rate of about 1% per year by the later 19th century. Due to extensive irrigation by canal networks Punjab, Narmada valley, and Andhra Pradesh became centres of agrarian reforms.
Detailed explanation-2: -Higher crop productivity. Decreased use of water, fertilizer, and pesticides, which in turn keeps food prices down. Reduced impact on natural ecosystems.
Detailed explanation-3: -Technology had reached Iowa farms in 1900, by way of the hand-crank telephone, Acorn cook stove, and updated farm equipment, such the horse-drawn plow, planter, hay press, and more. Corn, oats, and hay were the most common crops on turn-of-the century Iowa farms.
