I am no expert by any means as I put my first plots in last year. I was in your boat with an area that had never been worked. The plot worked amazing thanks to some advice. I started by taking a soil sample to the local co-op to find out what I needed to add as far as fertilizer, lime, ect. I then worked the ground. Not sure you need anything fancy to work the soil. I would get a disk for behind your wheeler(what I will be using this year) I spread my fertilizer and lime with a simple push lawn spreader. I planted some round-up ready soybeans with a broadcast spreader, used a piece of chanin link fence with wood to smooth the soil, and packed it all with the 4-wheeloer tires. I sprayed with round-up and a hand pump sprayer to keep the weeds down until the soybeans were established. The beans got so hammered(would have never made pods) that this year I will till them up in late July and plant a brassica, chickory, clover mix for fall. I tried a product by Evolved Harvest called Pro Graze which is what will go in come late july this year. I did all this on some logging trails in woods that were logged about 6 years ago so lack of sun was not an issue. I am currently trying to clear more ground so there is some food left come late fall.
Welcome to the world to food plots. Hi, My name is Bernie, and I’m a food plot addict after one year. Have Fun
