Ecuador Farm Tour Part 2 - Progress on the Original Food Forest Farm

Scientific Concepts & Nature Phenomena Presented

• Agroforestry / permaculture principles

  • Use diverse tree crops and understory plants to create a more resilient, “dual purpose” system (e.g., fruit and/or medicinal value).
  • Improve nitrogen cycling using legumes: beans/legumes help “put nitrogen in the soil,” reducing fertilizer needs. Intercropping beans between nitrogen-demanding trees is described as a soil-improvement strategy.

• Legume tree (Porton)

  • A locally known leguminous tree (“Porton,” with many local names) that produces beans and has notable flowers.
  • Emphasis on preserving underutilized/local biodiversity, since many people do not even know it—despite it being native.

• Soil fertility through waste recycling

  • Composting / compost leachate
    • Kitchen organic waste is placed in a bucket composting system (with holes at the bottom) that slowly leaks a nitrogen-rich liquid used to fertilize trees.
  • Animal manure as fertilizer
    • “Guinea pig poop” (locally abonar de cuy) is used as fertilizer.
  • Tilapia pond water irrigation
    • Irrigation uses water described as very nitrogen-rich, sourced from tilapia ponds and applied to fertilize crops.

• Aquaculture-linked nutrient reuse

  • A tilapia pond feeds the farm via pumped irrigation water.
  • Plan to add another pond growing azolla/duckweed, described as fast-growing and high-protein, intended to feed tilapia and possibly chickens (an integrated pond/animal feeding concept).

• Plant phenology & ecology observations

  • Fruit production variability across trees (e.g., a plum tree with abundant flowers; avocado trees transitioning from last year’s ripening to new fruit development).
  • Real-time pollination: a bee visiting passion fruit flowers.
  • Volunteer plants (corn) appearing without being planted, suggesting natural reseeding/seedbank dynamics.

• Tropical high-elevation agriculture constraints

  • Farming occurs at approximately 2,390 m elevation, with cold nights down to roughly the 40°F range.
  • Some crops are described as “prehistoric-looking” or better adapted to cooler climates; mountain papaya is grown specifically for high-elevation conditions.

• Ethnobotany / medicinal & edible uses

  • Multiple fruit and medicinal plants are discussed, including:
    • Mountain papaya (chambacan / Chilean papaya): requires cooking/fermentation; used for alcohol and tea. Fresh consumption is said to burn the mouth.
    • Passion fruit varieties: including granadilla and “badea” (giant passion fruit), noted for very large fruit and many flowers.
    • Lemon verbena / cedron: used as tea, described as having a sedative effect.
    • Rocoto (aji) peppers: noted as unusually flavorful “very sweet” hot peppers, with advice to limit intake.
    • San Pedro: described as a psychoactive plant similar to peyote, grown as a living fence to deter animals.

• Greenhouse microclimate management

  • A mesh “greenhouse”/nursery reduces wind and provides partial shade to help manage:
    • excessive equatorial sunlight
    • insect pressure
  • Seedlings begin in protected conditions before being transplanted.

• Ecosystem management via controlled grazing

  • Neighbor-managed grazing using ropes/stakes to limit animal entry into tree areas.
  • Framed as a win-win: controls grass/weed for the farm while letting neighbors’ livestock graze without damaging trees.

• Biodiversity & crop selection

  • Many citrus varieties are shown (e.g., oranges/mandarins, Meyer lemons, pomelos, “zebra lemons,” and lima/lemon-water types), suggesting selection for different flavors and uses.
  • Mention of stone fruit (peach/plum-like) and other orchard crops (figs, avocados, blackberries).

Methods / System Components (Outlined)

• Nitrogen-supporting plant strategy

  • Plant legumes (beans) among trees to increase soil nitrogen and reduce fertilizer needs.

• Liquid compost fertilizer system

  • Put organic waste into a bucket with holes.
  • Allow it to compost and leak nitrogen-rich liquid.
  • Use the leachate to fertilize trees.

• Aquaponics-like nutrient cycling (fertilizer irrigation loop)

  • Raise tilapia in a pond.
  • Pump pond water to irrigate crops.
  • (Planned) add duckweed/azolla to the pond to grow protein-rich feed for tilapia (and possibly chickens).

• Seedling nursery under mesh

  • Use mesh protection to reduce wind and harsh sun.
  • Provide some insect protection.
  • Transplant seedlings once established.

• Grazing control

  • Allow neighbors’ animals (horses/cows) to graze in open areas.
  • Use stakes/ropes to prevent access to tree crops.
