1800s Farming: Labor, Not Chemicals

1800s "success" is relative. Yields were low; most Americans farmed. Weed/insect control was hand-picking, hoeing, plowing. Few pesticides: pyrethrum, arsenic, nicotine. Fungicides: copper, sulfur, lime. Salt for weeds (limited).

1945: 14 labor-hours for 100 bu corn on 2 acres. 2002: same yield on <1 acre. That's progress—mechanization, genetics, chemicals, Extension education.
