Which Act established agricultural experiment stations aimed at informing farmers?

The Hatch Act is indeed the correct answer because it was specifically designed to establish agricultural experiment stations across the United States. Enacted in 1887, this legislation aimed to enhance agricultural education and research by providing federal funding for experiment stations. These facilities played a critical role in conducting research on crop production, soil management, and agricultural practices, ultimately helping to inform and improve the livelihoods of farmers.

The other choices reflect significant agricultural policies, but they serve different purposes. The Smith-Lever Act, for instance, focused on providing cooperative extension services to inform farmers about current agricultural research, while the Morrill Land Grant Act primarily designated land for state colleges to teach agriculture and mechanical arts. The Homestead Act encouraged the settlement of the American West by granting land to individuals, which was crucial for development but did not focus on research or experimentation in agriculture. Thus, the Hatch Act's establishment of agricultural experiment stations directly addresses the intent of informing farmers through scientific research and findings.
