Open Agriculture Technology

The appropriate use of technology

Open Agriculture Technology is a collective of growers, farmers, technologists, educators, consultants, manufacturers, distributors and researchers. All with the common objective to support and improve the global food system. Everybody everywhere eats. We don't compete. We create. We share.

Open Agriculture Technology: appropriate technology for agriculture. An open collective and knowledge base for growers, makers, educators, and problem-solvers. We don't compete. We create. We share. Panel 1, what Open Agriculture Technology is: a collective built around shared know-how. Growers, farmers, technologists, educators, consultants, manufacturers, distributors, and researchers with a common objective: support and improve the global food system. Everything here is free to read and use. No paywall; learn first, contribute when you're ready. Panel 2, the core idea: use technology only when it fits. Appropriate technology is fit to the need, the scale, the budget, and the skills on hand. Technology should extend the grower's skill, not replace it. Sensors, controls, automation, and AI are tools, useful when they fit, distracting when they don't. The right size is the one that fits. Panel 3, what you'll find, a practical map of the field: fundamentals (first principles in plain language), growing (environment, light, root zone and water, nutrition, monitoring, plant observation, control and automation, post-harvest, specialty and livestock), technology (sensing, monitoring, automation, and the data behind it), hardware (components, products, where they fit, and where to buy), a library of calculators and reference tools, and a plain-language glossary. Panel 4, how to use it: start where your need is strongest. Start here if you're new, learn the principles, follow the stack that matches your trouble or curiosity, use the calculators, hardware guides, and glossary, and put the data to work in the real world. The motion: learn (understand the problem), measure (read the plant and the place), build (choose tools that fit), use (turn readings into decisions), share (collective knowledge makes everyone better). Open knowledge. Practical technology. Better growing. Start with the basics, go as deep as you need. Grower first, open and free, fit over flash, community driven, global impact.

Appropriate Technology

Appropriate technology is technology matched to the job: the need, the scale, the budget, and the skills on hand. Used well, sensors, controls, automation, and AI let you do more with fewer hands. Used poorly, they become an expensive distraction from the business of farming.

It comes in every size. It might be a twenty-five-dollar sensor that tells you a greenhouse is getting cold, an alert instead of a trip out of bed to check. It might be a full commercial system that runs that greenhouse on its own. The right size is the one that fits.

Technology in
the World of Plants

Plants have basic needs, and reading those needs is the skill of an experienced grower. Technology doesn't replace that skill, it extends it. When it fits your operation, it can cover the work that only requires watching: an eye on things while you're away, on duty while you sleep, a heads-up when something moves out of range. When it doesn't fit, it costs more than it saves.

Sense It. Keep It. Use It.

Everything on this site hangs on one model, and it has three moves. Sense it: measure what is really happening, with a sensor, a meter, or your own two eyes and a clipboard. Keep it: the reading itself, with its when and its where, stored so you can always get it back. That part is the king. Sensors die, apps change, companies fold; the record you kept survives all of it and gets more valuable every season. Use it: the payoff. An alert at 2 a.m., a chart that puts last January next to this one, and every useful answer AI will ever give you about your grow, because it can't say a thing about a crop you never measured.

The two ends don't need to know about each other. A sensor doesn't care what reads its data, and software doesn't care which sensor wrote it. The data in the middle is the contract, and if you get that part right, every tool on this site (and plenty that haven't been invented yet) can plug into it.

Wherever You Are

The site is built for the dirt end and the data end alike. New to growing? The Fundamentals start at first principles, in plain language. New to electronics? Several sections begin at zero and assume nothing. Been at this for decades? There is real depth on sensors, open-source control, and the calculators you will actually reach for. Start wherever you stand today; it connects as you go. Glad you are here.

The Collective

We're growers, researchers, educators, and the trade, each carrying knowledge the others don't have time to gather. A grower who has fixed a nutrient lockout, a researcher who measured it, and a supplier who has seen it across fifty operations each know a piece of the same problem, together they know the whole of it. That's the point of sharing.

Everything here is free to read, and there is no paywall. A few tools ask for a login, the ones that save your own work. If you'd like to take part, the Join button at the top leads to the collective: who we are, and how to add what you've figured out.

The Five Doors

The top of every page carries the same five doors, and each one keeps to its own side of the fence. Growing holds all of the agriculture: the ten inputs a plant answers to, every method from soil to sealed room, and the crops themselves. Technology holds all of the technology, led by the projects you can flash from your browser tonight. Start where your trouble or your curiosity is strongest.

A few rooms sit one door in: monitoring and control under Technology, post-harvest and the specialty crafts under Growing, and the programs (funding, Extension, compliance) under The Collective.

Fitting
the Pieces Together

Each section has its own front door.

  • The technology, sensing, monitoring, automation, and the data behind it: the whole technology side, and how to put together a system that fits.
  • The Fundamentals, the library: lessons that teach the field from first principles, in plain language.
  • The Calculators, free calculators and reference tools: VPD, DLI, nutrients, and over a hundred more. Use them right in the browser.
  • Hardware, components and products: what each is for, where it fits, and where to buy it.
  • The Glossary, the language: VPD, DLI, EC, PAR, MQTT, LoRa, plain-language first.
