It is fast growing, and does not live much by the standards of the pines (more than 200 years), and prefers wet climates and humid soil.
This tree reaches heights of 18-30 m with a trunk diameter of 60-80 cm. The leaves are sharp, like needles, very thin, in groups of two or three, and 18-24 cm long. The cones are rounded red-brown, 5-15 cm in length with a short (2-3 mm) peduncle.
It is a main source for naval stores, it was used for the first time by the English in the navy to make waterproof wooden boats. This industry is one of the oldest in the United States and has supplied large amounts of resin and turpentine since colonial times. In the past, resin was practically the only product harvested from this pine, reaching a production peak in 1930. Production decreased considerably, due to labor costs and other market forces. After which the wood is harvested for the cellulose industry, producing sulphate of turpentine as a by-product. The high yield selection of tree resin has produced seedlings available in the market for this purpose and these seedlings have been exported to many tropical countries. The other uses of wood are mainly as post timber, often after a treatment for conservation. Bark and needles are used as fertilizer in horticulture, but the tree itself is rarely planted in gardens.
PROVINCE OF MISIONES, ARGENTINA
The primary activity of the province is based on agriculture, forestry and forestry. The logging began with the obrajes, which were followed by the sawmills; Nowadays, reforestation constitutes a more rational way of exploiting forest potential. Silviculture specializes in pine plantations, whose destination is paper-making plants.
INDUSTRIAL DESTINATION AND COMMERCIALIZATION
The extraction of logs comes in 92% of the implanted forest. They are mainly destined to the production of sawn wood and in volumes slightly inferior to cellulose pulp.
In the province they operate more than 900 establishments that process wood in different ways, cellulose activities - paper mills, saw mills, board mills, carpentry works, remanufacturing (machimbres, moldings, laminated boards and finger joint) production of packaging, furniture factory and parts, impregnating.
Misiones started exporting logs in the early 90's; It is currently in a stage of greater industrialization of its production and trade towards products with higher added value (sawn wood, moldings and panels), with the future claim to increase exports of furniture parts.
The wood industry is the first destination in importance of forest production that consists of the mechanical transformation of wood.
The largest diameter and density trunks processed in sawmills to obtain sawn wood and its by-products: pulp mills take advantage of sawmill and sawdust waste and also reconstructed panel plants.
The activity is located mainly in the northeast of the province in the area called Alto Paraná in the departments of Libertador Gral. San Martín, Montecarlo, Eldorado and Iguazú.
The province concentrates a good part of the country's sawing industry and particularly the greater part of the industry dedicated to sawing Pino wood.
Around 900 establishments make up the very heterogeneous activity from micro-businesses that work hand-crafted to large exporting industries with cutting-edge technologies with a strong predominance of small-scale establishments.
Around 10 sawmills constitute the most dynamic group, they have incorporated more modern machinery and technology, they are of greater dimension they have skilled labor, they are supplied in part by their own plantations and they produce with greater added value (among them fingen joint).
