Dear Liz, It is difficult to advise based solely from the soil test numbers below. A better soil test is by looking at the performance of plants, and searching for macro-and micro-organisms (worms are the easiest bioindicator). A pH 7 seems good for most crops (interesting for a forest soils), NPK is about 1:10:100. Low N, high P; good for flowers. Do you have more information on the history of the site? What's the geology of the site? Any past contamination's? What does your friend want to grow?
Do you remember the BDNow posts on wood chips? Perhaps your friend could benefit from these discussions. In a nut shell, she could chip some twigs (only from small branches) from the deciduous trees and incorporate a thin layer in the top soil. This method has been showed to produce excellent vegetable crops. It provides a good substrate and source of C/N for soil microorganisms.
