This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study wasconducted in a 14-year-old midrotation loblolly pine (Pinus taeda L.) plantation to assess the effects of fertilizationand vegetation control (a) on soil net nitrogen mineralization, (b) litterdecomposition and (c) foliar nutrient concentrations and use, and vegetationgrowth. Fertilization (none, 224 kg haP) and vegetation control (none, complete) treatments were applied in a 2x2factorial design in March 1998. Soil net nitrogen mineralization was assessedby monthly field and laboratory incubations, litter decomposition and nutrient(N, P K, Ca, Mg, S, Mn, Zn, B, Cu) release dynamics were determined by thelitterbag method, foliar nutrient use of pines and hardwoods was estimated fromlitterfall and foliar nutrient concentrations, and growth was determined basedon annual measurements of diameter and height. Field net N mineralization rateswere 19, 18, 31, and 78 kg ha for control (C, notreatment), fertilization (F), vegetation control (VC), and vegetation controlplus fertilization (VC+F) treatments, respectively. Relative treatments responseswere similar in the laboratory incubations. Litter mass loss duringdecomposition was reduced by 9% after 32 months by vegetation control, andfertilization had no effect. The mobility of the nutrients was as follows: Cud"d"

Available in PDF, EPUB and Kindle. Book excerpt: Carbon stored in soils represents the largest terrestrial carbon pool and factors affecting this will be vital in the understanding of future atmospheric CO2 concentrations. This book provides an integrated view on measuring and modeling soil carbon dynamics. Based on a broad range of in-depth contributions by leading scientists it gives an overview of current research concepts, developments and outlooks and introduces cutting-edge methodologies, ranging from questions of appropriate measurement design to the potential application of stable isotopes and molecular tools. It includes a standardised soil CO2 efflux protocol, aimed at data consistency and inter-site comparability and thus underpins a regional and global understanding of soil carbon dynamics. This book provides an important reference work for students and scientists interested in many aspects of soil ecology and biogeochemical cycles, policy makers, carbon traders and others concerned with the global carbon cycle.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effect of manipulating forest floor and harvest residue inputs on nutrient availability and carbon content in the context of intensive forest management. Treatments were removal and addition of forest floor and slash, and a reference. Tree volume, litterfall, and root biomass were measured to assess aboveground productivity and soil moisture and temperature, available nitrogen and phosphorus, O-horizon, and mineral soil for below ground processes. Organic matter additions increased stand bole volume, carbon at 20-60cm, and total nitrogen in the mineral soil. Severely removing the floor and harvest residues did not result in any large differences in below or above ground productivity, soil carbon or nitrogen pools. Removing a potential nutrient pool did not severely affect stand productivity through mid-rotation but could be a concern in subsequent rotations.

Available in PDF, EPUB and Kindle. Book excerpt: Nutrient deficient stands may respond favorably to nutrient additions. However, deficient stands must be efficiently identified. Leaf area has been shown to diagnose gross nutrient deficiencies while chemical analysis of foliage can provide more specific nutritional data. Nutrient levels fluctuate throughout the year and vary with crown position. Therefore, it is important to know the proper time and location for foliage sampling. The effects of nutritional treatments and time on foliar nutrient status were studied at SETRES. SETRES is a 2X2 factorial study of optimum nutrition and water additions in Scotland County, North Carolina, USA. Monthly foliage samples were collected and nutrient concentration and contents were determined for each sample for examination of seasonal variation. Foliage samples were collected in 1994, 1996, and 1998 and nutrient concentration and contents were determined for each sample for examination of vertical distribution patterns. Fertilization significantly increased the nutrient content of all nutrients added. Copper concentrations increased on fertilized plots even though no Cu was added. Fertilization caused changes in seasonal nutrient dynamics of added nutrients, especially B. Retranslocation efficiencies of N, P, and K decreased with fertilization while retranslocation rates of several micronutrients increased. Concentrations of mobile nutrients increased with crown height while concentrations of immobile nutrients decreased with crown height. Distribution patterns also changed with fertilization. For example, boron concentrations on fertilized plots increased with crown height while concentrations on control plots decreased with crown height. The ability to detect differences among sites and stability in concentrations are two criteria used to develop appropriate sampling protocols. Greatest sensitivity to detect site difference may occur at the times of year when the largest treatment differences occurred in this study. Unfortun.
