· Shoot production, relative to maximum, was higher at low moisture levels for F. ovina than for A. stolonifera. Differences of P, Fe, and potassium (K) concentrations in shoots and maximum relative shoot production between the two species, are consistent with their field distributions as related to soil moisture.

X3.1 Scope—This is a titrimetric test method for determin- ing phosphorus in samples of limestone, quicklime, or lime hydrate. A fairly large sample weight is required because this test method is not sensitive enough for an accurate analysis at the low levels of phosphorus frequently encountered in lime- stone rock.
