Some of the elements that fisher might use like gypsum, not sure if any of it is safe either though. Soil needs more research, is what most people think but growing things is getting harder not sure if the opensoil project can cover enough of the problems yet.

A more safer alternative might be using transition metals and post transition metals in plant soil. Though using transition minerals usually results in having to be treated with something that can cover coding soil too.

Soil needs microbiology, gas exchange and hydrology this is what makes elements available. Nothing needs to be added and all the elements are plentiful. We killed the microbiology, the research is already done. Keep many kinds of plants in the soil year round, stop adding chems, this increases yield 3x and water retention enough to reduce irrigation demand up to 70%. Strange thing is, this is free and removes a bunch of business models + gov subsidies from industrial ag and the universities that support them through "research". Just finished a year talking to farmers and growers of all kinds across the US.

Wow what a coincidence! I was just looking for open source soil spectral datasets earlier today. Thank you for posting.

What came up as the first result when you searched for open source soil spectral dataset if not this collection?

From the docs, Database: read only details on this page https://soilspectroscopy.github.io/ossl-manual/index.html#os...

1.4 OSSL mongoDB MongoDB is an Open Source noSQL DB hence fast and fully scalable and extendable (affordable costs for cloud solutions such as MongoDB Atlas and similar). TensorFlow and other cutting-edge ML algorithms can be easily integrated and served through a GUI.

To access OSSL DB best use the mongoDB either through a graphical user interface using Robo 3T, or by using the mongodb via R. The following parameters (database credentials) allow ready only access to DB:

'hence'? Does not follow. Sure, this particular implementation may be considered fast and scalable. The wording seems to indicate it is 'fast' and 'scalable' just because it is NoSQL.

Anybody have a good resource for building hardware for this sort of thing on a hacker budget? I’d love to build a Tricorder for my garden.

If you want to get some serious machine I would look for NirScan Nano. It is not cheap (~1,5k) but the performance is solid. Another possible route is getting mems based spectrometry sensor from Hamamatsu (~600) but building well performing acquisition board is not that simple and evaluation board is quite expensive.
