From twin-row 60-inch strip-till to intercropping and autonomous grazing, Zack Smith is always pushing the envelope on his 1,200-acre farm in Buffalo Center, Iowa. During his journey for healthier soils and lower production costs, the fifth-generation farmer developed an alternative style of strip intercropping — called stock cropping — that alternates strips of corn and annual pasture. The pasture strips are grazed by multiple species of livestock within an autonomous mobile-barn system.
