Ash, Protein, and Organo-Solubles of Jack Pine Seedlings in Relation to Soil Fertility
Abstract:Two-year-old jack pine seedlings of different origin were analyzed for their contents of ash, crude protein, volatile oils, ether extractibles, and alcohol-benzene extractibles. It is suggested that the low content of the alcohol-benzene soluble substances may be correlated with a greater susceptibility of nursery stock to parasitic organisms, and that the contents of ash and protein may serve as indicators of the balance of nursery-soil fertility.
