A spacing study of 3 conifers (white spruce, red pine and jack pine) was established at Moodie, Manitoba, on flat, sandy, nutritionally poor soils with a fresh moisture regime. Twenty years after planting, red pine had the largest average dbh, 15% greater than jack pine, while white spruce dbh was less than half that of the pines. Crown width. VanderSchaaf, C.L., and D.W.

Subsequent to the Cited by: 4. Prediction of cone crops several months in advance is possible. Cone production in red pine plantations has been responsive to cultural treatments.
Reduced stand density and increased soil fertility have markedly increased numbers of cones on trees at age 25 (anonymous ). More acres of planted slash pine are also approaching a merchantable condition than any other species, even though the bulk of the plantings has been in the last 20 years.
Because most planting is so recent, there has been a lack of information on the growth and yield of slash pine plantations.
