DOWNLOAD EBOOKA new method for extracting soil phosphorus with 0.5 molar solutions of NaHCO at pH 8.5 is described. The method is adaptable to rapid, routine, soil-testing procedures. A theoretical basis for development of the method is described. The extraction mechanism is based on the increased solubility of calcium phosphates as a result of lowering the Ca++ activity in solution. Also, the NaHCO extracts about one-half of the amount of phosphorus on the surface of soil particles, which readily exchanges with P in the soil solution.

DOWNLOAD EBOOKExcerpt from Estimation of Available Phosphorus in Soils by Extraction With Sodium Bicarbonate The level of phosphorus soluble In N ahcos at which most of the soils respond to applied phosphate, is lower for the field than for the greenhouse experiments (fig. Based on field experiments, using a 1: 20 soil to-solution ratio, the relationship between expected yield response to applied phosphate and the level of N ahcog-soluble phosphorus Is as follows: Below 25 pounds P205 per acre, a response, 25 to 50 pounds, a probable response; above 50 pounds, a response unlikely. These values were obtained from experiments using Wheat, oats, and alfalfa. The values may be expected to apply also for crops with similar phosphorus requirements, but the values may need to be lower for corn and higher for potatoes.

DOWNLOAD EBOOKStandardized methods and measurements are crucial for ecological research, particularly in long-term ecological studies where the projects are by nature collaborative and where it can be difficult to distinguish signs of environmental change from the effects of differing methodologies. This second volume in the Long-Term Ecological Research (LTER) Network Series addresses these issues directly by providing a comprehensive standardized set of protocols for measuring soil properties. The goal of the volume is to facilitate cross-site synthesis and evaluation of ecosystem processes. Chapters cover methods for studying physical and chemical properties of soils, soil biological properties, and soil organisms, and they include work from many leaders in the field. The book is the first broadly based compendium of standardized soil measurement methods and will be an invaluable resource for ecologists, agronomists, and soil scientists.

DOWNLOAD EBOOKPhosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%–30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil–water–sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant–microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.
