    Relationship between phosphorus concentration in soil solution and phosphorus in shoots of barley by J. Matula

    Published 2011-07-01
    “…Based on the diagnostics of P content in barley the following adequate P concentrations in soil solution were derived: 0.23-0.86 ppm P for colorimetry and 0.9-1.75 ppm P for ICP-AES. Using the concept of the boundary line of yield the critical P concentration in soil solutions was 0.8 ppm P for colorimetry and 1.3 ppm P for ICP-AES. …”
