Abstract: Three-year study of using organic fertilizers on naked oats in dry lands was done. The result showed that both naked oats yield and soil fertility could be improved by using organic fertilizers reasonably in dry lands. Proper fertilization could add oil nutrient and improve naked oats yield stably. On the contrary, none or less organic fertilizers in dry lands brought on low yield and infertile soil, and soil became hard for decreasing organic material year by year.
