DescriptionThe effects of N, P, and K on the growth of paper birch seedlings were tested in sand culture tests. Each element was tested singly at different supplies while holding constant the supply of all other elements. Seedling growth increased with increasing amounts of nitrogen. Three to 4 percent in the foliage indicated an adequate supply. Seedlings were relatively unaffected by different levels of phosphorus and potassium.
