e7“For most soils, the P concentrations in the soil solution were greater than the detection limit of the malachite green method (0.9 µg l −1 ) but smaller than its quantification limit (3.6 µg l −1 )”
e0“Agrostis capillaris was grown on the same soils labelled with carrier‐free 33 P‐orthophosphate ions to obtain L values”

Other claims from this paper (6)
- Method / resource E values were strongly correlated, but not identical, with L values for the same time of isotopic exchange.
- Method / resource The isotope approaches are not precise enough to detect the ability of a plant to access slowly exchangeable forms of P in these soils.
- Method / resource The isotope techniques can estimate the total fraction of added fertilizer P that remains available to plants.
- Method / resource E values from measured and extrapolated values of r t / R agreed satisfactorily.
- Method / resource Errors in n and r∞/R limited the precision of the E value estimates.
- Method / resource In soils with the least available P, the P content of the seed limited determination of the L value.
