Thanks guys. I have as much fun growing things as hunting, and the growing season is longer (even up here). Now, I am hungry for some venison to go with the veggies!
Calcium nitrate will raise soil pH as well, and obviously supplies calcium (a critical secondary nutrient). It is about $1/pound, and 15.5-0-0, so it is a more expensive N source than urea. I will use urea as well, but those trees are my babies right now, and apples use high amounts of Calcium.
That fence has issues. I only have a 3 ft ground, so this weekend I am putting in an 8 foot ground. We'll see how that works for keeping out the coons and bears. Next fall, one of my brothers may bear hunt here. It takes forever (8-10 yrs) to get a tag in WI. I will bait for them in September this year, so I may have some interesting trail cam pics in 2 months.
