Extract

The ratios of S cations (Na + K + Ca + Mg in m-equiv./100g.):2 anions (N + P + Cl + S in mequiv./ lOO g.), R values, in over 100 samples of Italian rye-grass grown in the field ranged from 0-33 to 0-92. Italian rye-grass, grown in the greenhouse at 11 levels of a nutrient mixture, had R values ranging from 0-58 to 1-36.
