How to Grow More Vegetables by John Jeavons

The Big Idea: Grow Biointensive (a variant of organic farming) produces more food per square foot while also building soil, using less water, using less fertilizer, and requiring less fossil fuel.

  • Industrial agriculture depletes 6 pounds of soil for every 1 pound of food produced.
  • Organic agriculture also depletes soil as it produces food.
  • Grow Biointensive¬†and permaculture builds soils as it produces food.
  • Grow Biointensive farming builds soil, uses less water, uses less fertilizer, requires less energy, and increases food production per square foot.
  • Grow Biointensive relies on human labor instead of external inputs.
  • Similar to Grow Biointensive: agroforestry, no-till Fukuoka farming, Asian blue-green algal wet rice farming, natural rainfall arid farming, and indigenous farming.
  • Build compost (using earthworm) for soil fertility.
  • Deep soil preparation (double digging) sets a foundation for building good soil.
  • Companion planting enhances growth and plant health.
  • Carbon-efficient crops produces carbon for compost.
  • Calorie-efficient crops produces lots of calories.
  • Open-pollinated seeds preserves genetic diversity.
  • A holistic farming system minimizes waste and required inputs.
  • Start small and build from there.
