Fig. 2: Water-soluble P concentration and seasonal change in plant height.

From: Spectroscopic analysis reveals that soil phosphorus availability and plant allocation strategies impact feedstock quality of nutrient-limited switchgrass

Fig. 2

a The water-soluble P concentration in the soils at the two field experiments at 3rd Street (silt loam soil) and Red River (sandy loam soil), respectively, with the boxes color-coded by the harvest times here and in subsequent figures. There was no significant difference in P concentration over the growing season at either location (p = 0.892). Soil P concentrations are significantly higher at Red River (p = 2.2 × 10−16). b The seasonal change of plant heights at the two field plots.
