The study looked at how different grazing times affect the soil seed bank in a desert steppe area. They found that rotating grazing times can increase the variety and amount of plant seeds in the soil, especially perennial plants. The soil seed bank was richest in the top 0-5 cm layer of soil and was influenced by factors like soil moisture and nutrients. Overall, rotating grazing times can help protect and use the desert steppe more effectively by increasing plant diversity in the soil seed bank.
