Agricultural Experiment Station; Agriculture -- New York (State). Decomposition of Sweet Clover as a Green Manure 133. Unlimed Slaked lime Ground limestone Fig. 11. RESULTS from different soil treatments, on plants grown for 118 DAYS were large nodules formed. However, nodules were present in abundance, as is shown by the fact that as many as sixty were counted on a single root system. The plants removed from the various pots were allowed to dry in the air and were weighed. They were then pulverized and bottled for later analysis. Similarly the soil samples were sieved and bottled after drying. These samples were analyzed for nitrates according to the methods previously described. The crops harvested were examined for nitrogen and crude fiber. The nitrogen was determined by the Gunning method, with the addition of copper wire as a catalyst. The crude fiber was determined according to the procedure outlined by the United States Bureau of Chemistr>\^ This determination was deemed important because the rate of decay of any plant material must be largely governed by the amount of woody tissue present. Thus it is desirable to know the percentage of crude fiber present at those stages when the plant might be used as a green manure. 5 Official and provisional methods of analysis, Association of Official Agricultural Chemists.
