• <br /> <br />SPECI%:, ADAPTABILITY <br />Twenty grasses and three legumes were selected for evaluation of <br />adaptability and performance on the deep sand. Most of the grasses are <br />selections of species native to deep sands in Colorado. <br />The plots were prepared by spraying with paraquat, rototilling, fertiliz- <br />ing with superphosphate at 40 pounds of P~acre, rolling, leveling, drilling <br />with a cone seeder, and mulching with manure. Seeding was completed on <br />t•1ay 24, 1978. Each plot includes 5 rows spaced i2 inches apart. The plot <br />layout is illustrated below, and the species are listed in mare detail on <br />another page. <br />49 <br />1 Rus. wil e L.
