Book Synopsis Ponderosa pine response to fertilization by : Robert F. Powers
Download or read book Ponderosa pine response to fertilization written by Robert F. Powers and published by . This book was released on 1978 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: First-year results of fertilization in a young ponderosa pine plantation on two contrasting soils were analyzed. Trees testing low in foliar nitrogen responded strongly to fertilization where brush had been removed, but failed to respond if brush remained. Height growth was doubled by certain treatment combinations on the less fertile Mariposa soil, but was not influenced by treatment on the more fertile Cohasset. Brush removal increased needle weight for trees on both soils. Increases in foliar biomass and nitrogen content of trees on treated plots suggest that rapid growth rates will continue.

Book Synopsis Growth models for ponderosa pine by : William W. Oliver
Download or read book Growth models for ponderosa pine written by William W. Oliver and published by . This book was released on 1978 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yields for high-survival, unthinned ponderosa pine (Pinus ponderosa Laws.) plantations in northern California are estimated. Stems of 367 trees in 12 plantations were analyzed to produce a growth model simulating stand yields. Diameter, basal area, and net cubic volume yields by Site Indices, 40 through 120 are tabulated for stands ranging in age between 10 and 50 years and in spacing between 6 by 6 and 12 by 12 feet. Tables also show diameter distributions by crown classes and stem volumes in cubic feet for plantation-grown ponderosa pine. These data provide both a standard with which to compare the effects of management decisions, and a performance goal.

Book Synopsis Ponderosa pine seeding trials in west-side Sierra Nevada clearcuts by : Robert L. Neal
Download or read book Ponderosa pine seeding trials in west-side Sierra Nevada clearcuts written by Robert L. Neal and published by . This book was released on 1975 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: In direct-seeding trials on the Challenge Experimental Forest, Yuba County, California, 27 combinations of seeding rates, aspect, and site treatment were tested. The best results were obtained on northerly aspects on unburned mechanically disturbed seedbeds with a high proportion of exposed mineral soil when seed application rates were high. Sowing at least 1 pound of seed per acre (1.12 kg per ha) consistently resulted in 400 or more seedlings per acre (988 seedlings per ha). Baiting for rodent control and attempted seed covering by "dragging" did not improve results. If regeneration requirements will be met by 400 seedlings per acre, these procedures for operational testing are suggested: (1) prepare 100 percent of the site by piling and burning slash and residual vegetation; (2) use seed that has had the standard endrin-arasanaluminum- dust pest repellent treatment, or equivalent; and (3) apply at least 1.5 pounds of seed (10,000 to 12,000 viable seed) per acre (1.7 kg, or 24,710 to 29,650 seed, per ha)
Book Synopsis Competing Vegetation in Ponderosa Pine Plantations by : Philip M. McDonald
Download or read book Competing Vegetation in Ponderosa Pine Plantations written by Philip M. McDonald and published by . This book was released on 1989 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planted ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) seedlings in young plantations in California are at a disadvantage compared with competing shrubs, forbs, and grasses. In many instances, roots of competing plants begin expanding and exploiting the soil earlier and in greater numbers, thereby capturing the majority of available resources and lowering pine survival and growth. Competition thresholds or "how much is too much?" are: for treatments where a cleared radius is prescribed, no weeds are acceptable within the space needed for maximum growth of pine seedlings during the establishment period; for treatments involving the entire area, crown cover values of 10 to 30 percent seem to be the level beyond which shrub competition significantly affects pine growth. Methods for preparing the site, which include mechanical and chemical methods, use of fire, and combinations of treatments, show the interaction of site and ensuing vegetation. Techniques for controlling competing vegetation from seed include preventing such plants from getting started by use of preemergent herbicides or mats (collars). To prevent sprouting, hardwood trees and large shrubs can be pushed over, thereby getting the root crown out of the ground, or if still in the soil, grinding it out with a machine. Once present, the effect of weeds from seed can be minimized by grubbing or spraying when young, by grazing plants with cattle or sheep, or by introducing plants of low competitive ability. Once sprouting weeds are present, their effect can be minimized by spraying with chemicals, or if palatable, by grazing with cattle or sheep. Costs range from as low as $10 per acre ($25/ha) for aerially applying herbicides to $711 per acre ($1757/ha) for grinding out tanoak stumps.

Book Synopsis Growth of Planted Ponderosa Pine Thinned to Different Stocking Levels in Northern California by : William W. Oliver
Download or read book Growth of Planted Ponderosa Pine Thinned to Different Stocking Levels in Northern California written by William W. Oliver and published by . This book was released on 1979 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth was strongly related to growing stock level (GSL) for 5 years after thinning 20-year-old poles on Site Index50 115 land at the Elliot Ranch Plantation in northern California. Five GSL's- basal areas anticipated when trees average 10 inches d. b. h. or more - ranging from 40 to 160 square feet per acre were tested. Periodic annual increment (PAI) in diameter decreased curvilinearly from 0.51 to 0.21 inch, with increasing GSL's from 40 to 160. But only trees in plots heavily thinned to GSL 40 (and briefly in GSL 70) grew faster in diameter after thinning than these same trees grew before thinning. PAI in basal area and net volume rose steadily with increasing GSL9s, reaching 9.0 square feet and 255 cubic feet per acre, respectively, at GSL 160. Apparently, even light thinning reduced volume production, but thinning still is recommended to shorten time until first commercial entry and to promote stand health.
