Said to be very cold hardy and low in seed toxins. Has anyone grown it as a cover crop? Fed the seed to poultry? Does anyone have seed to distribute?

"Hungarian vetch is native to eastern Europe and Caucasus and is well adapted to severe winter cold. The cultivation of this
species is expanding rapidly in Turkey, replacing less productive Vicia spp. (Sabanci pers. comm.). Adapted to heavy soils it
tolerates poorly drained soils better than other vetches (Duke 1981). The species has distinct promise as a grain crop as
relatively non shattering lines are available. Similar to V. villosa it is an outbreeding species where fertilisation and fruit set can
be increased by visits of pollinators (Zhang & Mosjidis 1995). Like all vetches, its main uses have been for hay and green
manure. In Moldavia, Avedeni (1989), found lines with high cold tolerance, high biomass, seed weight, seed yield and protein
content. ICARDA is focussing on the selection of genotypes with higher harvest index, reduced shattering and resistance to
Ascochyta blight. Progress has been rapid and several lines have produced seed and biological yields equal to the best V. sativa
lines with seed yields of 1372 kg/ha recorded at Tel Hadya, Syria.
The species is extremely low in known vetch toxins (canavanine, beta cyano-alanine) in two samples examined. Bell &
Tirimanna (1965) found low levels of VA3, recently identified as GEC [= gamma glutamyl - S ethenyl -cysteine](Enneking et al., 1998) in the seeds of this species but the
seed is certainly worth testing by monogastric bioassay to assess its performance. Coupled with its resistance to extreme cold
it is a potentially a very valuable feed, if not a food grain, and deserving of a greater breeding effort."

Some protease inhibitors Webpage may help slow SARS-CoV2 spread, since the virus depends on a human host serine protease present on susceptible cell walls to prepare to enter each cell. TMPRSS2 is a name for this serine protease.
One such inhibitor suggested, bromhexine, comes is derived from a compound  from Justicia adhatoda, also known as Webpage Adhatoda vesica . This plant is related to Justicia americanaWebpage, which itself is hardy to zone 4, unlike much of the rest of the genus. It ranges into Missouri nativelyWebpage.

I have no idea whether American water-willow helps prevent COVID-19, though.

Here's a 4 inch auger attached to the shortest one of three extensions made locally, with handle attached. You can see water in the hole - it's been wet lately. That slows getting the dirt from the hole - it slumps off the auger before surfacing. I hope to hit a sand or gravel layer soon, to ease accessing significant water in dry periods. Then I intend to put in a four inch well screen and casing.
The location is a little plateau part-way up a rocky ridge.

Perhaps, instead of quicklime, existing ground volcanic ash, pumice, olivine or basalt could be alkaline (pH 10+) enough.

So Emlid M+ = server, Hotspot = caster, cellphone = rover, all connected by Wifi, using NTRIP.
Or could correction data transfer via TCP using Wifi from Emlid M+ to cellphone.
I'd be satisfied with remaining within wifi range of base while I survey with cell phone, I think.

Maybe with just one M+ in a known position, I can get GPS position, make the correction factor, and send the correction factor to cell phone via NTRIP protocol, to get an inch-level-accurate cell phone position.

Not via NTRIP: "NTRIP does not support point-to-point communication e.g. you can not use it to transfer corrections from one Reach to another directly. In NTRIP terminology there are servers, clients and caster. Server sends correction to a caster and clients can receive them by connecting to that caster." webpage

Burton, I'm interested in how those Emlid M2's have worked out. Have you been able to use RTK correction from them via wifi in a cell phone, or do you use one Emlid M2 as rover and one as base?

If by cell phone wifi you mean NTRIP corrections I have not. My phone, and my wifes phone, cannot act as a hot spot but I am not sure it would work as well as the method I am using now where I use one as a base and one as a rover. The two of them combined was still less than the cost of a complete R2 unit and it is pretty easy to make an enclosure for the M2's using PVC.

Wow, so you spent about $1-1.5K dollars ? I misread 'M2' as 'R2'

To establish my own "known point" on the property I found a spot which was visible to most of the property and setup the base station letting it run for a good 8 hours. I then collected this data and downloaded the local CORS station data for the same time frame 17 miles away. Using RTKCONV I processed the Base station data then used RTKPOST with the CORS station set as the Base and the "Bast station" set as the Rover.

What's 'CORS' mean? And OPUS? I'm confused by "Bast station".

This produced several charts and graphs which told me my location for the "known point" within 3 cm square (about 1 inch). I copied the location provided and now when I "setup" over the "known point" I manually enter this as the location of the base station. So long as I have line of site to the base station from the rover I always have a "fixed" solution. If I don't then sometimes I have to wait a minute or two to get my location.

Just for fun I did try to upload my data to OPUS, the new method using the gravity based geoid, to compare but it was rejected every time. OPUS only accepts L1/L2 right now ... which is kind of odd given the accuracy of those are subpar compared to L3-L5 satellites. I think the accuracy I get with the Emlid M2's was worth the cost for sure.

My mapping rig for ODM somehow developed an unknown issue where it would no longer process a full set of data ... even previous dataset would fail at a specific point in the process. I have been trying to reconstruct it and document it this time so I can get processing again as I have a dataset from two weeks ago ready to go and it is over 1500 pictures :D

If there is interest I can post my whole process here.

I envision a set up with an Emlid M2 as a base station, connected, instead of to a LoRa radio, to a Wifi tranceiver. I can use my Samsung Note 3 cell phone as a hotspot, so transceive with the base station wifi, to get NTRIP corrections to my cell phone in real time.  Can you critique that vision? And what' s ODM?
