Commercial Fertilizers Increase Growth in a Yellow-Poplar Plantation
Abstract:Various nitrogen, phosphorus, and potassium commercial fertilizers applied at several rates to a 20-year-old, slow-growing yellow-poplar (Liriodendron tulipifera L.) plantation in southwestern Michigan increased height and diameter growth over a 5-year period. Adding 336 pounds of nitrogen, 73 pounds of phosphorus, and 139 pounds of potassium per acre increased height growth 100 percent and diameter growth 85 percent. Volume growth was increased over 200 percent. Leaf weight increased, color changed from a yellow-green to normal green, and leaf abscission was delayed by adding nitrogen. Height and density of weeds were greatly increased by adding nitrogen.
