This study was carried out on heavily grazed rangelands in Erzurum, during the years 2006-2009, for 4 years
period. In this study, four treatments that included artificial pasture, oversowing, fertilization and control
were applied on grazed and enclosed rangeland sites. A mixture of Crested wheatgrass (Agropyron cristatum),
alfalfa (Medicago sativa) and smooth brome (Bromus inermis) was used for rangeland seeding. Ammonium
sulfate and Triple Super Phosphate was applied on fertilization plots in sites grazed and enclosed site.
Botanical composition was determined by line intercept methods. After each erosive rain event, the amount of
soil (sediment) was determined in each plot. Across of four years, fertilization increased the grass proportion,
decreased other species proportion and sediment yield in both sites. Under grazing, over sowing increased the
grass proportion, and decreased other species proportion. Lower grass, higher legumes, higher other species
proportion and higher sediment yield determined in the third year compared to other years in both sites. The
enclosed site had higher grass, lower legumes, other species proportion and sediment yield than the grazed
one. Results of this study showed fertilization and oversowing treatment can be effective for soil protection in
enclosed and grazed rangelands, similar to this study area. Also, combined with short term enclosure
treatment the other improvement treatments can recommend for rangeland restoration and soil protection.
