West of Clarksville the ground runs flat and dark, and through the growing months the sod fields lie out like the world's largest lawn — green to the fence line, cut in long even bands. Ludema & Boyink Sod Farm LLC works from that same standard, turf grown and tended in the field and lawns kept the way the fields are kept: one height, clean lines, no ragged corners. New lawn and sod work goes in where a yard needs starting over, and the regular mowing, trimming and seasonal cleanups keep it that way once it has rooted. There is something plainly good about turf that knits in and holds — bare ground becoming a lawn you can walk barefoot across by midsummer. Around Clarksville and the Ionia County farm towns, grass is both the crop and the craft.
