FarmOS

farmOS is a web-based application for farm management, planning, and record keeping. It is developed by a community of farmers, developers, researchers, and organizations with the aim of providing a standard platform for agricultural data collection and management.

  • The farmOS server is built on top of Drupal in PHP.

  • The farmOS Field Kit app provides offline data entry in a native Android/iOS app, and as a progressive web app (PWA) at farmOS.app.

  • FarmOS Data Model | https://farmos.org/model/

    Data Model according to the farmos.py docs re: what can be accessed from the Drupal/FarmOS HTTP API with the farmOS Python client; the actual docs are more complete than the (Python, JS) API client docs:

    • Logs: A log is any type of event that occurs on the farm, from a planting to a harvest to just a general observation.

    • Assets: Assets are any piece of property or durable good that belongs to the farm, such as a piece of equipment, a specific crop, or an animal.

    • Areas: An area is any well defined location that has been mapped in farmOS, such as a field, greenhouse, building, etc.

    • [Taxonomy] Terms: FarmOS-install-configurable terms for various categorization purposes. E.g. quantity units, crops/varieties, animal species/breeds, input materials, and log categories. See “Endpoints” above for specific API endpoints URLs.

AgStack

AgStack is a new open source Linux Foundation umbrella project “to enable development of code, models, extensions and frameworks, as well as the contribution and curation of data, focused on driving efficiencies in agriculture.”

Electromagnetic energy

  • TODO: EM spectra

  • Plants use UV: Ultraviolet and Infrared energy to convert CO2, H2O, […] to O2 and respirated H2O with VOCs (Volatile Organic Compounds).

  • Photovoltaic (PV) panels convert photonic EM particle/waves into electron field disturbances than can be stored in energy storage devices like batteries.

  • Thermophotovoltaic (TPV) panels are like PV panels that also harvest energy from Infrared (heat) energy, which is also present at night.

UV: Ultraviolet

Warning

Prolonged exposure to Ultraviolet light may cause cataracts. Reduce your exposure to Ultraviolet light with wraparound UV-protective eyewear.

UV-A

UV-B

UV-C

  • UV-C [TODO: band] sanitizes

  • There are UV-C sanitizer bottle and wand kits for camping. see Water Quality

Ultrablue

  • Broan SurfaceShield [TODO: by ]

Infrared

“Thermal” or “heat” energy is infrared energy.

Grow lights

LED Grow lights

  • LED grow lights waste less electical energy as heat, so they are more energy efficient than traditional incandescent or fluorescent grow lights, and they heat the plants less.

Soil Food Web School
  • “What is the Soil Food Web? | Soil Food Web School” https://www.youtube.com/watch?v=uAMniWJm2vo

    • Soil has a biome (food web insects, earthworms, microrganisms fungi, bacteria) that breaks down organic matter and releases nutrients in plant-available form.

  • See also: Hügelkultur

Terracing

  • Terracing is one of the most ancient methods of maximizing yield from available sloped land.

Hügelkultur

  • It’s a layer cake: Instead of just soil, build beds and containers from a base of logs, leaves, a bit of pine, and maybe sand or loam or sphagum peat moss, and then bagged soil if you must, and then another layer of actual compostable materials for plants to grow up throw.

  • Actual Hügelkultur involves mounding up and growing on the side of the mounds, but the principles of composting apply to container beds (that can get hot due to composting) as well.

Water Distillation

Solar Water Distillation

  • A simple solar water distillation setup: Two buckets, a window pane at an angle so that the condensate drips into the clean water bucket; evaporation leaves behind most microbes.

Self-watering Planters

AGardenPatch Grow Box

Note

I learned of these “Grow Box” self-watering tomato planters from an insert in a seed catalogue which I received after ordering bulbs online.

  • UV resistant plastic; years of use.

  • 50 lbs when full of potting mix and water

TODO: Grow Bow procedure:

  1. Potting Mix

  2. [Organic] weed control fertiziler patch

  3. Keep the reservoir full of water

  4. Keep either Vegetable Oil or Olive Oil on the water to prevent mosquitoes.

    • Bulb baster

    • Bottle pour spout

    • They and others sell “Mosquito Dunks” tablets to drop into standing water.

Ecology

Lawn and Garden

  • It is Lawn and Garden because lawn and garden are ecologically linked: a healthy lawn feeds bugs and birds to the beds.

Organic Lawn care

  • TODO: Organic lawn care book (ebook) from amazon citation, summary

    • You can only mow a few times per year.

      • Electric String Trimmer

Note

Organic lawn care does not solve for e.g. termites.

  • Hori Hori garden knife

  • Bulb planter (*)

  • Auger drillbit (*)

  • (*) See: No-till TODO

Hori Hori Garden Knife
  • The Fiskars Hori Hori has a forked point for weeding, one serrated edge, a plastic sheath that can be washed out with a garden hose, and an orange rubber handle.

  • Ron Finley mentions the a Hori Hori garden knife as an essential gardening tool in the TODO Ron Finley Gardening Masterclass.

String Trimmer
  • A string trimmer is a long-handled device that spins a string (or a cutting head) according to the pressure applied to the trigger.

  • An electric string trimmer can be used to cut grass, edge trim, and mulch.

  • There are various bad and good ways to hold a string trimmer.

  • Electric is much nicer because there’s no exhaust to position, it starts without a pull, and because Electric Lawn Equipmentn.

Electric Lawn Equipmentn
  • Combustion produces CO Carbon Monoxide, which is an oxidant “free radical” that binds with many things easily (due to valence electrons).

    Burning wood, oil, and gas produces byproducts including Carbon Monoxide, which are not good for anyone, and particularly unhealthy for persons with e.g. asthma.

    Combustion occurs particularly when the carbon bonds break at low heat.

    A (fluidic) “flame” that we’d see in Earth air which has oxygen is either combustion or plasma. Plasmas are different state of matter. Combustion is a critical reaction where the carbon bonds keep breaking due to the locally-freed thermal energy; and the other particulate is typically thermally ejected into the surrounding fluid without a sustainable filtration system.

  • First Berkeley/Oakland, CA, USA and then the State of California have banned sales of new gas lawn equipment; you can only buy electric lawn equipment in stores is the plan in CA, USA first.

  • You can buy lawn equipment that uses the same batteries as your power tools so that you only need so many multi-battery chargers.

    • [ ] TODO: USB-C PD for Tool vendors (@DeWalt, )

      • Use case: A Squid-like charger with (reversible USB-C) ports on the batteries would be real nice but not as easy to carry as a pail with a handle and a physical battery pack interface spec.

      • Use case: Use extra tool batteries as spare USB power packs

      • [ ] Physical battery pack interface; there are a bunch of vendor-to-vendor adapters on e.g. amazon and there could be an optional spec and adapters for using old batteries with new tools

      • [ ] Battery reconditioning requires fire suppression to be safe for zoning, from what I understand.

Warning

  • [ ] Local battery recycling centers; how to open the plastic pack and set batteries aside to take to the battery recycling place.

Pollinators

Bees
  • Bees are crucial to our whole way of life; bee are crucial to Earth ecology.

  • Unfortunately, we’ve diminished poplatitions of bees with lawn mowing and herbicides, and with pollinator-killing chemicals in our environment.

    • TODO: neoctinides (?) kill bees, there are many alternatives

  • Dandelions and Clover are the first food of the bees in the spring.

  • Most honey is White Clover Honey.

  • White Clover grows in lawns that haven’t been Weed and Feed’ed.

    • [ ] TODO: Is there a weed and feed that doesn’t kill clover, which is green all summer?

Hydroponics

Wikipedia:
  • Plant grow well with just water and nutrients

  • Water flow is cruicial to Water Quality.

  • PVC does add microplastics to the plants.

Aquaponics

Wikipedia:
  • Fish urine includes nitrogren, which is fertilizing.

  • 3 stage aquaponics setup; high to low:

    • Stage TODO: Hydroponic and/or Container growing medium

    • Stage TODO:

    • Stage TODO: Water, [Watercress,], [Mosquito] Fish

      • Watercress filters water

      • Mosquitofish eat mosquito larvae (and from watercress roots)

Aeroponics

Wikipedia:
  • Plants grow fine when you just mist the roots with water and nutrients; you don’t need soil or cycling water.

  • Aeroponics is ideal for controlling root rot.

  • Aeroponics does not require soil as an input; but does require nutrients from some other sustainable source. (see: Hügelkultur).

  • MIT OpenAg has open source CAD designs and software for desktop, closet, and warehouse aeroponis systems.

No-till

  • One argument: tilling soil excessively (or at all) disturbs the soil ecology by exposing the top layer of the soil microbiome to oxidation and sanitizing UV-C radiation.

  • No-till gardening says don’t till and:

    • disturb as a little as possible

    • add natural mulch and/as compost

    • use plants to break the soil

    • dibb holes to sow (see: TODO: ref:Agricultural robots)

Laser weeding

TODO:
  • Laser weeders zap just weeds and may roll along the rows on tall legs and e.g. wheels.

  • Automated [solar] laser weeding products apply laser radiation to weeds identified by a omputer vision machine learning model; probably a neural network trained with associations between inputs sensor images and outputs (typically labels from humans performing image segmentation on [portions of] sensor images).
