Potassium Cycling in a Fertilized Slash Pine (Pinus Elliottii Var. Elliottii Engelm) Ecosystem in Florida. Voss, Roylyn Lee, Potassium Cycling in a Fertilized Slash Pi. Western brackenfern contributes to potassium cycling on sites and is associated with high levels of potassium [28,].
Fertilization of cultured plants increases frond dry weight; using both nitrogen (N) and phosphate (P) increases rhizome length, while using N, P, and potassium (K) increases both rhizome length and rhizome dry weight [ 49 ].
Nitrate-nitrite nitrogen (NO x-N) concentration in soil solution at and cm depths from 2 weeks before to 52 weeks after fertilizing slash pine with kg ha 1 diammonium phosphate (DAP. The biotic cycling of potassium (K) in forest systems has been relatively understudied in comparison with nitrogen (N) and phosphorus (P) despite its critical roles in maintaining the nutrition of.
Abstract. Fertilization is a silvicultural practice used for increasing forestland productivity in the southern U.S. Effective operational use of fertilizers requires diagnostic systems, used individually or in combination, that accurately identify site nutrient status, needs, and potential by: Swan, H.

Pulp Paper Res. Inst. Can. Tech. Rept. Cited by: Pine stands with species producing longer needles, such as longleaf (Pinus palustris) or slash pine (Pinus elliottii), are the preferred pine straw source areas, although loblolly pine stands can also be used for pine straw production.
Stands developed for pine straw production begin early with a control burn shortly after crown closure (before. A negative correlation betweenfohar tannin and potassium concentrations was found on plots that were fertilized with nitrogen and phosphorus.
On southern pine sites that are fertilized with phosphorus, the accelerated growth of planted pine and invading vegetation may create new nutrient limitations.

In Marchthe site was fertilized with kg ha"1 of dolomitic limestone (56% CaCOs, 32%. The template for the following discussion of methods is illustrated in Fig.

Title: Nutrition and fertilization response: a case study using hybrid poplar: Creator: Zabek, Lisa M. Date Issued: Description: Three hybrid poplar (Populus trichocarpa x Populus deltoides) plantations on the east side of Vancouver Island were fertilized with N, Nand P, and N, P, and K at the beginning of the third growing season, followed by fertilization with N in the fourth growing Cited by: 6.
We examined three hypotheses in a nutrient dose and application frequency study installed in juvenile (aged 2–6 years old) Pinus stands at 22 sites in the southeastern United States. At each site, eight or nine treatments were installed where nitrogen was applied at different rates (0, 67,kg ha−1) and frequencies (0, 1, 2, 4 and 6 years) in two or four replications.
Phosphorus Cited by: 9. The three most important are the gaseous (e.g., the carbon, oxygen, and nitrogen cycles), the sedimentary (including the phosphorus, sulfur, calcium, magnesium, and potassium cycles), and the hydrologic (water vapor to rain to streams to oceans to vapor).
Goals / Objectives The main objectives of this study are to: 1)Evaluate the crown ideotype approach to clonal testing in loblolly pine to determine if there is a consistent growth response to silvicultural treatments among clones that are classified into the same crown ideotypes; 2)Determine impacts of increasing genetic uniformity, from open pollinated to control pollinated to clone, on.
Following fertilization of forest plantations, high accumulations of nutrients in the forest floor creates the need to assess rates of forest floor decomposition and nutrient release.
The study site was a year old experimental loblolly pine plantation in the North Carolina Sandhills Region. Soluble and insoluble N, P, carbohydrate and phenol-tannin fractions were determined in foliage and Cited by: 8.
"Fire does volatize the most needed nutrients such as 98 to % loss of nitrogen (N), 70 to 90% loss of sulfur (S), and 20 to 40% loss of phosphorus (P) and potassium (K) in field bio-mass." According to the Forest Service, "Because N is such an important nutrient in these ecosystems, the replenishment of N lost by volatilization during a fire.
Over the last 50 years, cooperative research on planted southern pine management among SE U.S. universities, government agencies, and forest industry has developed and facilitated the widespread implementation of improved genetic and silvicultural technology.
The impact of the regional research cooperatives is difficult to overstate, with current members managing 55% of the privately. Response of slash pine to bedding and phosphorus application in southeastern flatwoods: Mann JR, W.

Examples of organic mulches include leaves, pine straw, pine bark, and wood chips (wood such as pine, cypress, cedar, oak, eucalyptus, etc., which has been shredded or run through a chipping machine)/5(51).
Mulching decreased the differences in soil and plant mineral content between fertilized and non-fertilized plots, also highly influenced yield and growth performance.

Slash-and-burn or swidden agriculture works where there are few people and large tracts of land, because the natural fallow can be long enough to restore nutrients and biomass.
