Pigweed is really wild amaranth, right? I see the seed heads of pigweed here contain seeds that could be utilized like a crop for poultry, I should think. Pigweed also brings up deep grouned nutrients up to the soil stratus to benefit garden plants. What do you think? domestic amaranth is an 'iffy' seed crop to grow in this zone. Pigweed grows. Does anyone know the nutrient value of the seeds of wild amaranth or pigweed?
