Been planting organic non GMO Soybeans and lentils and other grains and pseudo grains to make fodder with. First time we've done anything like this, always planted veggies though.
This autumn we plan to plant wheat, barley, rye and spelt. All organic non GMO of course, already have the seed.
Also planted a bunch of other goodies for the chickens too but that's kind of off topic. Before we knew about fodder planting grains for the critters seemed useless with the small field we have. Making fodder changed my mind about having enough space to raise feed grains etc.
Now I think we'll even be able to make our own breads etc. and feed the birds too.
Still plan on ordering some different heirloom wheat seeds but we have einkorn, black emmer and an heirloom variety of wheat. Pretty stoked about growing seed for fodder and fermented grains from the ground up organically.
I would be careful about soy.
