BIOINTENSIVE is a whole-system approach to gardening and farming that
builds soil fertility in a relatively short time, so that fertilizer
inputs (other than compost) become unnecessary, or almost so, thereby
making the garden and farm as sustainable as possible. Learn the
principles of double-digging, composting and soil-building, intensive
planting, companion planting, carbon farming (compost crops), calorie
farming, and open pollinated seeds. $31. To register click here: growbiointensive.eventbrite.com/# or call 650-493-6072.
