I'm a Northerner and I've only had my place 3 years. When I started, there was just a single overgrown trail right up the middle of my place and the entire 80 acres (the dry part at least) was a mono-culture of trees all the same age, about 15 years. We didn't sniff a living thing the first Fall hunting season. Not a deer, hardly a bird or squirrel. It was just a barren waste. A post-deer season walk through the entire place that first year turned up ONE SET OF DEER TRACKS ON 80 ACRES. We weren't bushwhacking all over the place during hunting season either, barely intruding on the edge. So I don't think we spooked the entire property.
The next Summer, we made that skinny trail into a skinny, long food plot, piled on the 19-19-19 and WR. That Fall, we saw a couple deer, and a grouse or two started to inhabit the edge, and along the edge of the access trails be began to create.
The next Spring, I waited for green up and sprayed, started adding lime and fertilizer per the soil test. Mid-Summer, I sprayed again and spread a Fall mixture of WR, annual clover, and a brassica mixture. Last Fall, I had three doe family groups hitting that plot every day like clockwork. I saw grouse out eating clover, wading into the middle of the plot even, every sit. Squirrels were running all over. Cameras caught a zoo; black bear, bobcat, wolves, skunk, racoon, porcupine, deer... Things have changed.
This year, I sprayed early and poured lime, gypsum and a mountain of oats on my plot in late Spring. The oats grew thick and lush, covered the soil, added OM, helped shade out weeds. Late Summer I fertilized per a soil test, spread my brassica/clover/WR mix into the oats, sprayed and knocked them down to cover the seed. Despite a lack of rain for a month after planting, I've now got the best brassica plot I've ever seen. Broadcasting 200LBS of urea / acre a month after planting, right before a good rain may have helped.
Obviously, I'm still dependent on chemicals. I'm still pouring synthetic fertilizer. I'm hoping this will change in the next couple years. I don't know if I could have accomplished any of this without chemicals but I don't want to use them forever.
I know for a fact, the diversity and quantity of wildlife has increased dramatically at my place, in just a couple years and all I've done is make food and edge habitat. There's a lot more to do. I look forward to improving bedding cover and natural browse as time goes on. It's fun. It's satisfying, and it keeps me out of the bar.
But, the change in my place has been dramatic by adding food and edge, slowly improving the soil. It's night and day. And, it's fun.
