Show ENSILING THE GREEN CROPS Extensive Investigation Carried on by Nebraska Experiment Station Six Small Silos Used. Th department of agricultural chemistry of the experiment station and college of agriculture of Nebraska Nebras-ka has been carrying on an extensive investigation during the last year on the chemistry of the processes which take place during the ensiling of various vari-ous green crops. Special attention bas been given to silage made from mixtures mix-tures of alfalfa and sweet sorghum. Six small silcs holding about one ton each were filled in September, 1914, with various mixtures. Two of these silos were opened during the second week of August, 1915, and the silage in each was found to be In perfect per-fect condition. The first silo contained con-tained a mixture of one part sweet sorghum and one part alfalfa, while the second contained a mixture of one part sweet sorghum and two parts af-falta. af-falta. Alfalfa alone will not make silage, sil-age, because the plant does not con- tain enough sugar to insure the production pro-duction of sufficient acid to preserve the silage. The acid produced from the sugar in the green plant by bacterial bac-terial action preserves the silage. By mixing sweet sorghum with the alfalfa the necessary sugar is supplied. |
