| Fig. 3 Effects of different numbers of added nutrients on aboveground biomass in Hulun Buir steppe (mean ± SE). Eight nutrient factors are nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, iron and micronutrients (iodine, boron, manganese, zinc, sodium, molybdenum, copper, cobalt and chlorine as one factor). N0P0, no nitrogen and phosphorus addition; N1P0, nitrogen addition; N1P1, nitrogen and phosphorus co-addition. The amount of nitrogen and phosphorus added is 20 and 2.95 g·m-2·a-1 (modified from Peng et al., |
