Why do you say that? What is so different? Do these plants function in a completely different manner than the ones we plant?

It could be partridge pea that's growing wild or an Austrian winter pea that we plant….both plants are legumes that serve the same general function in the plant ecosystem. Same if we’re talking about broadleafs or grasses….It could be millet…milo…crabgrass or Bermuda grass but all of those plants fill the niche of the “grass” specie in the plant ecosystem and bring those certain properties to the table. One of the big advantages for why people grow sunn hemp is for its ability to produce large amounts of woody biomass. That’s one of the major benefits your getting…high C:N ratio biomass production. IF deer decimate the field and it doesn't produce that biomass then those advantages are lost. You can read all you want to about the advantages of buckwheat and incorporating its biomass back into the soil but the reality in plots like mine ends of being a field of little browsed off stalks.... not a field of biomass. This is where these other plants we consider “weeds” have the advantage. They are going to actually out compete these other plants like sunn hemp and buckwheat from a soil health perspective because they can actually withstand the browsing pressure and still produce that massive crop of biomass. These plants are still taking up nutrients from the soil and recycling them into OM as well.
