Biomass and Nutrient Results - Spring 2011

We measured total above ground biomass production as well as nitrogen and phosphorus accumulation in the biomass.

Fig1Spr2011

Figure 1. Aboveground biomass sampled from plots at 10 locations during late April/early May 2011. The five locations on left represent relatively lower productive potential due to lower soil fertility (especially N) and/or sampled earlier when compared to those locations on the right. Data represent averages across the 7 seeding mixtures. Bars are minimum and maximum values.

Figure 2. Nitrogen captured in aboveground biomass at 10 locations during late April/early May 2011. The five locations on left represent relatively lower productive potential due to lower soil fertility (especially N) and/or sampled earlier when compared to those locations on the right. Data represent averages across the 7 seeding mixtures. Bars are minimum and maximum values.

Data represent averages across the 7 seeding mixtures. Bars are minimum and maximum values.
