Info

The value of the data obtained from this study is that we now know the range of nutrients in all components of this forest type. If we measure the available soil nutrients and a few other parameters from other forests of the same type on different soils, we should be able to estimate how much fiber can be removed safely from those sites, and how much nutrient will be released and lost as a result of burning. Know- ledge of the total and available soil nutrient content will help us judge whether nutrient shock is likely to occur from any combination of treatments. Since mainly poor soils are of concern the task of finding these soils and marking them as "chemical 1y fragile" is the next problem. LITERATURE CITED Carl isle, A. 1975.
