Being as how this field is currently planted and growing buckwheat, then it's obviously very well capable of growing a different crop. What kind of planting equipmentdoyou have access to? If your resources and/or time are somewhat limited than about the easiest growing and lowest maintainence plantings that I know of are Forage Oatsor a Brassica/wheat/oat blend like Bio-Logic Green Patch Plus

Hereare some of my Forage Oat plots. They fill out quickly and the growth is explosive.





Here's a Bio-Logic Green Patch Plus plot that I blended with just a bit more of the Forage Oats. It tuned out extremely well this seaosn. All these plants were Fall planted around the first of Sept.
