Effects of 12-Year Nitrogen Addition and Mowing on Plant-Soil Micronutrients in a Typical Steppe.

ABSTRACT: Changes in soil micronutrient availability may have adverse consequences on grassland productivity, yet it's still largely unclear how concurrent human practices, such as fertilization and mowing, affect micronutrient cycling in the plant-soil systems. Here, we measured six essential micronutrient (Fe, Mn, Cu, Zn, Co and Mo) contents in both plant pool (separated as aboveground plant parts, litter, and belowground roots) at the community level and soil pool (0-10 cm depth) after 12-year consecutive nitrogen (N) addition (0, 2, 10, and 50 g N m^-2 year^-1) and mowing in a typical steppe of the Mongolian Plateau. The results show that (i) medium-N (10 g m^-2 year^-1) and high-N (50 g m^-2 year^-1) addition rates significantly increa
