Book Description
Excerpt from Comparative Value of Legumes as Green Manures In experiments conducted by the chemical department of this station, 32 varieties of legumes were grown on two soils of different types. One soil was a dark brown clay from the station grounds, the other, an acid red clay from the Kunia district of the Island of Oahu. Three crops were grown of each of the 82 varieties of legumes, using 4 pots for each trial of each variety. At maturity, the plants were removed, weighed, and analyzed for nitrogen. Analyses of the soil for nitrogen were made before planting and after, removing the crop. These analyses indicate that a large portion, at least, of the nitrogen in the legumes was Obtained from the air through the associated root tubercle bacteria.
