Closed-Loop Backyard Farm Design — FarmPal

Design a backyard farm where every output becomes an input: kitchen scraps feed compost and animals, manure feeds gardens, garden produces food and animal feed, creating a self-reinforcing loop that reduces purchased inputs to near zero over 3-5 years.

Principles

  • Every waste stream is a misplaced resource kitchen scraps, yard waste, greywater, and manure are all valuable inputs
  • The chicken-compost-garden triangle is the core engine of a backyard farm
  • Closed loops reduce outside inputs (fertilizer, pest control, animal feed) by 60-80% within 3 years
  • Stacking enterprises in time and space: chickens in orchard eat pests and fertilize; garden follows chicken tractor rotation
  • A well-designed 1/4 acre backyard farm can produce 40-60% of a family's food while improving soil year over year
  • Water cycling through rain catchment → garden → greywater → trees closes the most expensive resource loop

Action steps

  1. Map all input/output flows

    Draw your current system: what comes in (water, feed, fertilizer, food) and what goes out (waste, runoff, yard debris). Every outflow is an opportunity to close a loop.

  2. Install the compost-animal-garden triangle

    Position compost between garden and animal housing. Kitchen scraps split between compost and animals. Animal bedding goes to compost. Finished compost goes to garden. Garden waste goes to animals and compost.

  3. Add water cycling

    Rain catchment from roof → storage → drip irrigation → garden. Greywater from kitchen/laundry → mulch basins around fruit trees. Overflow → infiltration swale. Goal: zero potable water used for irrigation.

  4. Track input costs annually

    Measure purchased inputs each year. A well-designed system reduces costs 20-30% per year as soil improves, perennials establish, and animals forage more. By year 3-5, many backyard farms run on <$500/year in purchased inputs.

Benefits

  • Reduces purchased inputs by 60-80% over 3-5 years
  • Eliminates organic waste from trash stream
  • Builds soil that improves every year
  • Creates genuine food security from a small footprint
  • Models regenerative systems at household scale
