Trees were measured, foilage and soil sampled for chemical analyses, and grass biomass sampled, dried and weighted. Soil and foilage samples have not yet been analyzed. The data follow the first growing season and indicate only that some subsoiling is better than none. Future measurements should show more differences between levels of subsoiling. A small study was installed to evaluate a fortified sludge pellet and a commercial 21 g fertilizer pellet for use as starter pellets on borrow pits. The starter pellets are considerably better than no pellet at all and it appears that, initially, the commercial fertilizer pellet is superior to the fortified sludge pellet. Since grass benefits little from pellets, starter pellets will likely be more useful in areas where grass competes with trees for water and nutrients. 2 tables.
