The soil is usually better along a water source/creek bed,plus there's going to be good moisture in a low lying area.We have put a few food plots up high on Ridge Tops,it depends on the quality of soil there...if You can try to get a soil sample and PH reading from each area and decide from there?

We just planted several small Durana Clover Food Plots in the Big Timber in area's that were thinned out for timber stand improvements,we cleaned off the area,cut a few more smaller tree's out then raked it out and ran a small ATV disc across it while spreading out granulated lime then seeded the clover on top.Time will tell on wether our hard work paid off!
