Table 1.
Characterisation of the NW (North Wyke, grassland soil), AL (arable low pH), AH (arable high pH) and GM (growing medium) soils after nutrient application.
Fig 1.
Mean dry matter (DM) yield of botanical groups across the GM, AH, AL and NW soils.
Error bars are one standard error. The average least significant difference (LSD) across treatments was 0.497.
Fig 2.
Mean dry matter (DM) yield of species across all of the soil types.
Errors bars indicate one standard error. The average least significant difference (LSD) across treatments was 0.491.
Table 2.
Summary of the P values of the REML analysis for the concentration and uptake of each nutrient for soil, botanical group, plant species (within a botanical group) and the interaction of soil with each of these.
Fig 3.
Mean forb, legume and grass Cu concentration and uptake (concentration * plant dry matter yield), and Se concentration and uptake when grown on each of the four soil types: Growing Medium (GM), Arable High pH (AH), Arable Low pH (AL) and North Wyke (NW).
Error bars indicate the confidence interval of the back-transformed mean. The least significant difference (LSD) of the back-transformed data were 1.241, 1.421, 1.304 and 1.416 for Cu concentration and uptake and Se concentration and uptake respectively.
Fig 4.
Mean Mn concentration in the plant material of each of the four forb species tested when grown on the Growing Medium (GM), Arable High pH (AH), Arable Low pH (AL) and North Wyke (NW) soils.
Error bars are the confidence interval of the back-transformed mean. Average least significant difference (LSD) across all treatments on the back-transformed scale was 2.045.
Fig 5.
Mean Cu, Fe, Mo, S, Se and Zn uptakes (dry matter yield * concentration) by each of the four forb species tested when grown on the Growing Medium (GM), Arable High pH (AH), Arable Low pH (AL) and North Wyke (NW) soils.
Error bars are the confidence interval of the back-transformed mean. Average least significant differences (LSD) of treatments on a back-transformed scale were 2.181, 2.477, 0.0007, 2.314, 2.155 and 2.369 for Cu, Fe, Mo, S, Se and Zn respectively.
