John Aeschliman turns over a shovelful of topsoil on his 4,000-acre farm in the Palouse region of eastern Washington State. The black earth crumbles easily, revealing a porous structure and an abundance of organic matter that facilitate root growth. Loads of earthworms are visible, tooâ€”another healthy sign.
