Elk City, Okla., no-tillers Spencer Smith and his father, Jimmy Smith, talk about the Dalton Ag Mobility 600 fertilizer applicator they use to broadcast cereal rye into standing cotton, which is planted in 40-inch rows. The machine is PTO-driven and the Smiths can travel 6-7 mph to cover a lot of ground efficiently. The family has been seeding cereal rye on their farm for decades and say rye seeding between the rows has helped suppress weeds and markedly improve water infiltration and soil retention.
