Extract

(1) There is a definite seasonal variation in the mineral content of the pastures examined between the months of May and October, which is most clearly shown by the CaO, which rises to a maximum and then steadily falls; and to a less extent by the silica-free ash, P2O5 and Na2O.

(2) The chlorine content did not show a corresponding variation; its tendency being to maintain its high percentage through the later part of the season.

(3) The nitrogen, on the whole, showed a variation corresponding with the calcium, though the range was markedly less.
