Figure 3From: C:N:P stoichiometry and nutrient limitation of the soil microbial biomass in a grazed grassland site under experimental P limitation or excessRegression analysis of biomass C (C mic (μg C g−1soil dry weight)) and biomass P (P mic (μg P g −1soil dry weight)) in different soil P-fertilisation treatments. See legend in figure. There are duplicate points for each of six plots per treatment.Back to article page
