Figure 4From: C:N:P stoichiometry and nutrient limitation of the soil microbial biomass in a grazed grassland site under experimental P limitation or excessScatter plots of total soil C:P or soil available C:P ratio versus microbial biomass C:P ratio. Values are shown in comparison to the 1:1 line (dashed) for different soil P-fertilization treatments. See legend in figure. Points represent the mean of duplicate measurements for each of six plots per treatment.Back to article page
