no-till agriculture, earthworms etc are not killed by tilling integrated pest management, don't kill so many useful insects contour farming, reduces soil erosion by rainfall. If furrows are down the slope of the land, water can cut deep channels. If the furrows follow the contours, a lot of water stays where it falls and crop rotation.? Different crops use different nutrients and may actually replace some nutrients that are used used by other plants. eg legumes fix nitrogen in the soil. https://en.wikipedia.org/wiki/Crop_rotation
