I did a little 10 minute walk around my field earlier with some company that stopped by and there was at least a dozen or more plants that we easily pointed out while walking around that were being hammered......purple vervain, florida pusley, pokeweed, dewberry, blackberry, teaweed, golden rod I believe but may have that one wrong....I mean really there weren't many plants period besides the grasses and dog fennel that didn't have moderate to heavy browsing....and the seed was all free. I just fixed my soil and got it right. I believe the deer can tell the difference in plants grown in fertile, properly functioning, nutrient rich soil versus the same plants grown in lesser soil conditions. I believe they can tell the difference in the plants growing where there's 4200 lbs/ac of calcium in the topsoil versus 200-300 lbs....I think they can tell the difference in the optimal K levels and balanced pH..etc….
