Note 84 — Chapter IV · THE POSSIBILITIES OF AGRICULTURE—(continued).

Prof. Ronna gives the following figures of crops per acre: Twenty-eight tons of potatoes, sixteen tons of mangolds, 105 tons of beet, 110 tons of carrots, nine to twenty tons of various cabbage, and so on.—Most remarkable results seem also to have been obtained by M. Goppart, by growing green fodder for ensilage. See his work, Manuel de la Culture des Maïs et autres Fourrages verts, Paris, 1877.
