Were you aware while doing the grading, of the benefit to deterrence of the deer, the slope would provide?
Yes, I had seen it over a decade earlier on my BIL's farm, he had several such patches for various "crops"
mellons here, corn there, green beans over there,,, etc,,,
he had over 1,000 acres, and put these little 100x100 patches where the best growing conditions existed.
They had the dozer to grade, etc,,, he produced all the produce for his family and all of his employees'.
The fences were far better than mine.
