Black Walnut and food plot plants?

[bigboreblr]

I know walnut trees give of that chemcial that attacks other trees. Any harm done to clover, cereal grains, turnips, etc.....

I removed walnut trees near my apple trees. However, these younger 15ft tall walnuts are secluding my mother-in-laws house from the new house out back. They'd be pretty grumpy me hacking them down right now. Do Have a shade line or spruce and pine to replace them at some point.

I think the impact from black walnuts is really overstated.

I did some allelopathy research during my post-doc on another plant, but looked into published literature that is out there. I think the majority of plants are using allelochemicals of some kind to make themselves more competitive, but they are very plant specific. It is almost impossible to accurately measure the effect of the allelochemicals in the field without separating other negative impacts like shade and resource competition.

I have had pretty good luck with clover in one of our plots that has three massive black walnuts growing in it. We had some extra rye left over and I wanted to try overseeding this clover plot.

Looks pretty good, even with the shade in there.

I took care of the walnuts by the apple trees because it's blocking my west side. I thought afternoon sun on the soil is more improtant than morning light for apple trees.

If you really wanted to remove any doubt, I would just be focused with what is growing in the drip line of the tree. Most of the juglone is coming from the leaves. I wouldn't plant an orchard near black walnuts, but that is more because of the shade than anything else.

While black walnuts are the bane of our existence for many of the varieties in our garden, they have not seemed to impact our food plots or grains. The clovers (Ladino and Red) don’t seem to be impacted by the walnuts.
