Abstract

We measured survival, growth, and foliar nutrition of white ash (Fraxinus americana L.), sycamore (Platanus occidentalis L.), and black walnut (Juglans nigra L.) on a regraded minesoil (Typic Udorthent, pH 2.9) treated with four combinations of papermill sludge depth by incorporation methods. We also compared tree performance when protected from mammal damage by tube, netting, or no shelters. Sludge rates were approximately 860 Mg ha−1 for a 15-cm depth and 3450 Mg ha−1 for a 60-cm depth. After 4 yr, tree survival was 65% when either 15 or 60 cm of sludge was deep incorporated by a backhoe. Survival was 43% if 15 cm of sludge was rototill incorporated and 3% if 45 cm of sludge was surface applied over the rototiller-incorporated sludge (60 cm total sludge depth). Trees were tallest (236 cm) on 15 cm-backhoed, intermediate (204 cm) on 60 cm backhoed, and shortest (130 cm) on 15 cm rotilled treatments. Ash (56% survival) survived better than sycamore (40%) and walnut (36%). Tree survival was best (61%) in tubes, intermediate (43%) in nets, and worst (28%) with no protection. Ash and walnut were tallest (177 cm) in tubes, intermediate (124 cm) in nets, and shortest (103 cm) with no protection. Sycamore height (305 cm) was not affected by the shelters. Foliar nutrition of trees was adequate except for possible low P in ash. In summary, tree survival and growth were good if sludge was incorporated by backhoeing and trees were protected by tube shelters.
