1. Introduction. Modern agriculture has dramatically increased crop yields—at a high environmental cost, however (Tilman et al., ).Many countries have therefore adopted environmentally sustainable agricultural production as a long-term policy objective (e.g. OECD, ).One of the key environmental concerns related to agriculture is the eutrophication of Cited by: Phosphorus levels in Lake Erie and surrounding waterways are an increasing concern, and agricultural practices have been identified as a potential source of phosphorus. Excess phosphorous from U.S. and Canadian sources that runs into municipal drains can promote the growth of algal blooms in downstream water bodies, like Lake Erie.
The title ‘Phosphorus in Agriculture: % Zero’ is synonymous for make-or-break. And it stands up to the promise. This book sends an important message as it delivers background information, intrinsic hypotheses, validation approaches and legal frameworks, all for balanced phosphorus fertilization in agriculture. SERA Is: the Southern Extension and Research Activity (SERA) - 17; an Information Exchange Group (IEG) administered through the Southern Region Land Grant Universities, and is composed of research scientists, policy makers, extension personnel, and educators. Our mission is to develop and promote innovative solutions to minimize phosphorus losses from agriculture .

[Goswin Heckrath;] -- The proceedings from the Nordic Phosphorus workshop, Februaryaddress the role of decision tools in the process of abating phosphorus (P) losses from agricultural land in the Nordic and Baltic.
Phosphorus management is an important aspect of the USDA-NCRS nutrient management standard. Anyone applying animal waste or fertilizer in a nutrient-impaired subwatershed must determine potential phosphorus loss from each field. This publication describes the P-Index or Phosphorus Loss Assessment Tool that is used in North Carolina for this purpose.
10 Tools for Assessing Phosphorus Loss from Nordic Agriculture research groups. A single conceptual framework for a P decision tool is applicable in the Nordic and Baltic countries, even if it requires adapta-tions of its design. Important lessons can be learned both from the P in-dex widely adopted in the United States and the UK-developed.

A widely used method for predicting P-loss from agricultural land is the ‘Phosphorus Index’ (PI) tool, developed by Lemunyon and Gilbert [Journal of Production Agriculture (), 6, – The Phosphorus Source Assessment Tool.
The Phosphorus Source Assessment Tool is used to estimate the relative contributions of various land uses and point sources to P loading in a watershed.

An assessment tool using the Phosphorus Index will assist field staff working with landusers to identify sensitive areas and recommend management alternatives to reduce risk of P losses.
Problem The movement of P from the agricultural landscape is a concern because of the potential problem of surface water eutrophication and subsequent growth. phosphorus is present in the soil and identifies where a high potential for phosphorus loss exists. The PMT also allows farmers to evaluate management options they can use to reduce the risk of phosphorus losses from agricultural fields to nearby waterways.

Book: The Role of Phosphorus in Agriculture, Published by: American Society of Agronomy, Crop Science Society of America, Soil Science Society of America The Role of Phosphorus in Agriculture, [ Preview (PDF) ] Use and Limitations of Physical-Chemical Criteria for Assessing the Status of Phosphorus in Soils doi The actual phosphorus loss from agricultural land to surface waters is a complex function of climate, topography, soil type, soil phosphorus status, phosphorus fertilisation, and land management.
These factors vary greatly in space and over the year, and the hydrological pathways for phosphorus losses also vary greatly in space and time. Phosphorus (P) loss from agriculture in runoff is a primary cause of eutrophication in freshwater.
To identify the key areas with high-risk possibility of phosphorus loss is very important for the control and management of non-point source pollution. As a case study of Yellow River basin, Phosphorus Index (PI) was modified and applied here.

A New Approach to Assessing Phosphorus Use Efficiency in Agriculture By A.E. (Johnny) Johnston and J. Keith Syers It is frequently stated that P is used inefficiently in agriculture, with percent recovery of P applied in fertilizers usually between 10. Hydrologic and water quality models are more accurate, but are prohibitively complex for conservation planners to use.
Pasture Phosphorus Management (PPM) Plus was developed as a user-friendly P and sediment loss prediction tool based on the Soil and Water Assessment Tool (SWAT), a popular comprehensive hydrologic and water quality by:.
phosphorus is considered as non point source of water pollution and agriculture is the major contributor for this source. The phosphorus content causing eutrophication may be alarming from environmental point of view but may be very less from farmer point of view, but continuous loss of P from soil can be critical.U.S.
