Walnuts are allopathic look under the tree there all dead everything is it stops shit growing underneath it
it’s how it keeps only what it needs
But I use plants like that as weed killers
You take allopathic plants boil em up or cold press em
spray the allotment and just about every plant dies for around 4 weeks no seed germs
I spray it in my seating area and along my fence to keep the weeds off
so I don’t think it be good to add to soil could be wrong

walnut tree produces allelopathic chemicals that inhibit the growth of other plants. The black walnut that grows in much of New Mexico is the most prolific producer of this chemical, but the English walnut and Carpathian walnut that grow as far north as central New Mexico produce the chemical in lesser amounts. The walnut tree and other plants produce allelopathic chemicals to discourage other plants competing for water and nutrients.
As an example of "turnabout is fair play" in the plant world, some grasses that cannot compete with trees for light will produce chemicals to inhibit root growth in trees. This explains why some trees planted into a lawn are slow to establish and begin growth.
All plants are not equally affected by juglone, the chemical produced by the walnut tree. Perhaps the most well known plant sensitive to the toxicity of the walnut tree is the tomato plant, but many others are also affected. Relatives of the tomato plant, such as eggplants, chiles, potatoes and petunias, are sensitive. In addition, some ornamental plants are also sensitive. These include potentillas, lilacs, columbines, lilies, peonies, mugo pines, and various privet shrubs. Blackberries, cabbage, and rhubarb should also be kept at least 50 feet from the dripline of a black walnut (may perhaps be grown closer to other walnuts).
Many plants can be grown under a walnut tree. Those that are not sensitive are various beans, corn, beets, onions, and raspberries. Ornamentals tolerant of walnut trees include forsythia, hawthorn, oaks, wild rose, daylilies, iris, phlox, Shasta daisy, and Virginia creeper]
