What Do Weeds Tell You About Your Soil?

- Can weeds help you learn about your soil? Obviously the gold standard is the soil test but many plants can teach you what is going on in the dirt you are looking at. Some are indicators of poor soil and there are several that are barometers pointing to potentially great soil. Another advantage of knowing these plants is that you get to know several great wild edibles along the way.
Simply looking at the plants that grow in any location tells me much more than a soil test ever could about the environment of that location.
For an internship during my time at an agricultural college I looked at what weeds say about the actual state of the soil. Ph, N, P, K, and moisture content of species found in the wild are catalogued into this program called "SynBioSys". By overlapping these values, we hoped to predict the soil parameters.
We managed to get an accuracy level for pH of 1.5, which is not enough to give actionable insight. Phosphate also worked, kind of. But with nitrogen and potassium, we missed the mark entirely, or the accuracy level was such that the result didn't actually hold any statistical meaning. It deserves mention that the fields we looked at had 3 times the recommended amount of nitrogen. This was 50 times the amount of nitrogen associated with the weeds we found. It is very, very hard to make any definitive conclusion based on present weeds, these are just very rough indiciators in the best of circumstances, and completely false in the worst.
Great video. God bless you.
"Weeds" to some, "lesson books" for others.
Great statement. Thanks.
grow sudan sorghum and chop and drop it 2 to 3 times back into the soil.
Subscribed and like buttoned. Thank you, I'm a new gardener and I don't know what is going for what. So many weeds in my garden and because I want to grow regeneratively Im not sure what needs to be removed or if it should or shouldn't be removed. Because some say the weeds are good so leave them be. Excited to learn alot
I put horse manure tea in part of my flower garden and suddenly shepherd's purse started growing in that area. I never used that product again and I picked the shepherd's purse and after some time I stopped seeing shepherd's purse.
Can we assume that a plant growing in magnesium rich soils will also be high in magnesium? Great video!! Blessings from Nova Scotia
Good stuff brother
Thank you. Blessings.
i have purslane is growing in poor soil and it grows really big
I wanted a video of the same kind with weeds that grow in kerala. Unfortunately no one has done yet.
Weeds dont live in my back yard. No wonder my plants are not thriving. Also any tips for jumping worms? How to kill them?
Excellent video! I thought you should know that Regenerative Farmers of America youtube channel has stolen your content almost verbatim.
I wonder what blackberries, poison hemlock, and thistle are indicators of, because I'd like to feel more positive toward them...
oh yeah, bind weed too
Well two of them are edible. ...
What kind of camera and lens do you use?
Sony A7sii. Lens is an old manual Nikon 50mm 1.2
Oye!! My garden is confused! 😂😂 I have dandelions, wood dock, a couple Mullen, and lambs quarter. So I'm guessing it may be calcium deficient, but nitrogen rich?
I need to get a soil test done for sure. Lol.
Mine as well! I have dandelions and stinging nettle 😅
my soil is bare
Mulch it... Plant some cover crop. Put activated biochar... That's the beginning
