Biodiversity II: Effects of Plant Biodiversity on Population and Ecosystem Processes - Experiment 120


Soil phosphorus

Years Available: 1994 - 2017

Principle Investigators

Tilman, David
Furey, George

Sampling and lab analysis

Extractable Bray P was measured from archived soil samples collected from each plot before planting in 1994 at 0-20 cm and soil samples collected after 23 years of growth in 2017 from depth increments of 0.20 cm, 20.40 cm and 40.60 cm. The University of Minnesota Research Analytical Laboratory (Saint Paul, MN, USA) analyzed these soil samples for extractable P using a standard Bray-1 extract (0.025 M HCl and 0.03 M NH4F) and analyzed colorimetrically. Lab methods from; R. Eliason, R. J. Goos, B. Hoskins, Recommended chemical soil test procedures for the North Central Region, Rev. ed.. (Missouri Agricultural Experiment Station, University of Missouri, 2015).
