Growth and yield of a 59-year-old red pine plantation (Plot 99) in Northern Minnesota

Seven thinning treatments with residual densities between 60 and 160 ft3/acre (13.8 and 36.8 m2/ha) of basal area were applied to a highly productive (site index, 81 ft (24.7 m); base age, 50 years) red pine (Pinusresinosa Ait.) plantation. After 10 years, periodic basal area growth was maximized over a lower and much broader range of residual densities than previously found in lower site quality stands. Total and merchantable cubic foot volume growth for the 10 year period was not significantly different between treatments. Application of these thinning treatments on a 6- compared with a 10-year interval reduced total and merchantable cubic foot volume growth while increasing the average stand diameter.

St Lawrence River

Multiple regression equations have been developed to predict yield from young red pine and jack pine plantations. Data from 446 sample plots representing young red pine and jack pine stands located on the south shore of the St. Lawrence River between Quebec and Montreal were analysed. The red pine plantation yielded more than the jack pine. However, in plantation both species yield more than in natural stands. Taking into account the age and spacing of the sampled plantations, the equation obtained can provide information on yield of red pine and jack pine stands the maximum spacing of which is 3 × 3 m, up to the age of 45 and 35 years respectively. The equations will allow the construction of preliminary yield tables for both species.

Current Growth

The fertilizers, Mg at a rate of 100 lbs/acre and K at 200 lbs/acre, were applied around each of 15 red pine (Pinus resinosa Ait.) to promote increased growth in a 20-year-old plantation which had failed to fulfil growth expectations. Successive measurements of diameter and height showed that the fertilizers stimulated diameter significantly after the second growing season, but height only after the third growing season. Beneficial effect of fertilizer applications on diameter and height persisted, and the differences in diameter and height between treated and untreated trees at the end of the seventh growing season was equivalent to two years' current growth.
