I am a big fan of barnyard fertilizer for growing stuff, I have a food plot I plant in the woods about 75 yards below my house. I don't hunt it but like to watch deer on it. I made the clearing for the plot by widening an existing spot in the woods, the soil is so poor it will hardly grow weeds.
On a good year with plenty of rain I can get a marginal stand of plot seed to come up but the deer eat it to the ground as soon as it comes up. I decided to enrich the plot so stuff will grow faster than the deer can eat it.
The local cattle sale barn has countless tons of this stuff, give it away for free and will even load it on a trailer for you.
This manure is green, right out of the cows so this year's application may burn up my plot but I have to start somewhere. I have a front end loader on my little tractor to unload the stuff and spread it.
