The efficient use of phosphorus (P) is essential to many agricultural and environmental issues. This bulletin reviews, analyses and synthesizes information on the efficient use of soil and fertilizer P. It presents information on the plant availability of soil and fertilizer P, with an emphasis on soil plant interactions. The focus is on the changing concepts of the behaviour of both soil and fertilizer P and on the need to define and assess their recovery and, thus, P-use efficiency more appropriately.

Studienarbeit aus dem Jahr 2012 im Fachbereich Agrarwissenschaften, , Veranstaltung: Soil and Environment, Sprache: Deutsch, Abstract: It has been widely accepted that organic materials (plant and animal sources of organic matter) from plants and animals play important role in sustaining and improving soil structure, soil quality, soil function, soil health, soil fertility, and overall crop performance in agricultural production. Organic materials are potential important sources of micro and macro nutrients in agricultural soils environment (Hood, 2001). They affect physical, biological, chemical, and ecological processes in soil. They improve soil structural quality, soil water holding capacity, soil infiltration, soil organism biodiversity, and soil nutrient availability (FAO, 2005). The utilization of the animal and plant materials is not only an economic benefit for soil and crops but also for human being and his environment. Bio-organic Manure (BOM) is processed from some organic materials (animal or plant or combinations of all). Process of decomposition of homogeneous and heterogeneous organic materials will be rapidly undergoing some changes due to microbial functions, temperature control, and water actions. This is different from fresh organic fertilizer where natural decay process is brought about by the action of heterogeneous microbes present in the organic matter. [...]

About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer.

This booklet describes best practices for agricultural nutrient management in Ontario. It begins with a review of the importance of nutrients to crops and the effects of nutrient additions on the environment. Basic background information on nutrients follows, including the nutrient cycle, the behaviour of nutrients in soil and plants, and types of nutrient deficiencies found in Ontario. Sources of nutrients are then reviewed, including naturally occurring sources, fertilizers, manures, and wastes. The final sections cover testing for nutrients and interpreting test results, and application of nutrients on the farm. Includes glossary.
