Response Of Douglas Fir Seedlings To Nitrogen Sulfur And Phosphorus Fertilizers

Excerpt from Response of Douglas-Fir Seedlings to Nitrogen, Sulfur, and Phosphorus Fertilizers This study, therefore, was designed to study effects of N, S, and P additions on growth and nutrient content of Douglas - fir seedlings grown in two forest soils in a lathhouse. We are aware of the limitations of pot tests in providing prescriptions that can be directly applied to field situations. However, the very limited information about Douglas - fir nutrition now available and the high cost of establishing field tests strongly justify preliminary experimentation with seedlings.
