Phosphorus Mobility Study. AARD. Adding manure to soils greatly increased the amount of dissolved P exported in runoff. In contrast, manure additions did not lead to increases in sediment P export. Since dissolved P poses the greatest threat to surface waters, manure management strategies are necessary to help prevent surface water contamination. This research shows that soils vary in their ability to hold P. In addition, increases in soil test P with similar manure additions are not always the same for different soils.

Prospects For The Recovery Of Phosphorus From Animal Manures: A Review. Julian Greaves, Phil Hobbs, David Chadwick and Phil Haygarth. Inst. of Biological, Environ. and Rural Sci. (IBERS), North Wyke, Devon, EX20 2SB UK ; This paper reviews the potential for P recovery from animal manures as a method of increasing the sustainability of the global P cycle. The P content of animal manures produced annually in the UK is currently estimated at over 120,000 t. Similar quantities of P are produced in manures in the Netherlands and an estimated 600,500 t are produced annually in the US. Up to 65% of manure P may be associated with an organic moiety. However, current methods to identify these including HPLC and 31P NMR are under developed while P fractionation procedures give only operational definitions. Combinations of current technologies developed for the treatment of sewage are likely to prove effective in the recovery of P from manures.

An Approach to Nutrient Management on Dairy Farms [334 KB pdf]. Abele Kuipers, Frits Mandersloot, and Ronald L. G. Zom, Animal Sciences Group, Runderweg 6, 8219 PK, Lelystad, Netherlands - In the European Union, groundwater should contain less than 50 mg of nitrate/L. In The Netherlands, regulations based on P limited the amount of manure applied per hectare. A more balanced P supply to the land has been achieved by transport of manure from surplus to deficit regions. In animal production experiments, lowering the P content of concentrates and mineral supplements reduced P losses without an adverse effect on production.

North Carolina is one of the leading US states in livestock and poultry production. In 1993, the on-farm inventory was approximately 4.4 million animal units, as defined by the U.S. Environmental Protection Agency. Current trends toward farm consolidation, specialization and intensification are sound from an economic and management perspective, but may fail to adequately address important environmental impacts. A nutrient assessment was initiated to determine where clusters of livestock and poultry are located, to assess manure generation by county, to determine the recoverable manure nutrients which can be made available for plant growth, to determine the quantity of nutrients required for agronomic crops and forages in each county and to determine the balance in each county between plant available manure nutrients and agronomic crop needs.
Effect of Animal Manure Applications on Crop Yields and Soil Quality. Randy Killorn, Alfred Blackmer and Antonio Mallarino. Dept. of Agronomy, Iowa State University - The components described in this proposal focus on how land application of liquid swine manure affect crop production and soil quality. We intend to find how time, method, and rate of liquid swine manure application affect mineralization and nitrification rates (Dr. Alfred Blackmer), phosphorus availability (Dr. Antonio Mallarino), and corn and soybean yield and recovery of nutrients (Dr. Randy Killorn). All the components are based on the assumption that funding will cover three growing seasons and allow time for preparation of a final report following harvest in the final year. The final report will include an economic analysis of the crop production data to help decide the type of manure management that should be recommended.
Fertilizing Corn in Minnesota. (2006). George Rehm, Gyles Randall, John Lamb, Roger Eliason, U. of Minnesota Extension. In Minnesota, corn is grown on more acres than any other crop. Nationally, Minnesota ranks among the top five in production. Average corn yields have improved steadily over the past several decades. While general fertilizer use contributed substantially to yield increases in the past, total fertilizer management which optimizes nutrient efficiency will be needed to increase future production and profitability.

Nutrient Management for Environmental Protection: Challenges and Changes in the U.S. (1999). J. T. Sims and A. N. Sharpley - Northeastern Branch of the American Society of Agronomy & Soil Science Society - Nutrient management has always been a key component of agricultural planning. Decades of research have developed and refined efficient, economic means to optimize plant nutrition and thus increase crop yields. Government advisory agencies (e.g. Cooperative Extension, USDA Natural Resources Conservation Service) and private agricultural consultants have been able to transfer much of the nutrient management research into best management practices (BMPs) that are well-accepted by farmers today.
Poultry Manure Management Planning (MNP) -ID-206, Cooperative Extension Service, Purdue University, West Lafayette, IN 47907 - Manure contains the nutrients needed by crops. Taking advantage of manure's nutrient value can reduce your fertilizer costs by about $50/acre. Many Indiana poultry operations generate large volumes of manure. For example, 30,000 layers produce 40 tons of manure a month or nearly 500 tons a year. Proper handling, storage, and application of manure from poultry operations protect Indiana's water resources and can increase profits of bird and crop enterprises. Managing these nutrients for maximum benefits and minimal environmental impact requires some planning. A Manure Management Plan (MMP) brings together information about crops, livestock, and manure handling for your farm. This information will help you develop a better long-term plan for maximizing the value of your poultry manure.

Field Tests for the Nutrient Value of Manure. James C. Barker, Biological and Agricultural Engineering, NC State University, Raleigh, NC; North Carolina Coop Extension Service Pub #EBAE-181-93 (Mar 1996) - Taking a sample after agitation and sending it to a testing laboratory for nutrient analysis is always advisable but does not provide the results in time to be used to determine application rates. Therefore, a rapid field test to estimate nutrient content of slurries that could be conducted on site immediately prior to land application would improve the applicator's ability to manage the loading rates of livestock manure. NC State Univ. researchers have spent approx 2 yr evaluating 4 such "quick-test" field methods for determining the nutrient value of manure. Two of these methods appear to offer promise and will be reported on.
