Agricultural phosphorus and water quality (1999)

Does phosphorus reduce water quality? Is the problem nitrogen or phosphorus? What fields and practices cause high phosphorus in agricultural runoff? How can farmers protect our water quality from excess phosphorus? This guide demonstrates the complexities of reducing losses of phosphorus from agricultural land and the range of options available to help reach water quality goals.New 3/99/5M

Managing manure phosphorus to protect water quality

Soil and Fertilizer ManagementAGRICULTURALMU GuidePUBLISHED BY MU EXTENSION, UNIVERSITY OF MISSOURI-COLUMBIALand application rates for manure historically have been structured around protecting groundwater resources from overapplication of nitrogen in manure. However, high levels of phosphorus accumulation in some fields receiving manure and the decline in water quality in some Missouri lakes and streams have led to questions about this nitrogen-based strategy. Confined livestock operations are a major source of income for Missouri farmers. Livestock accounts for about 50 percent of farm cash receipts, with a value near $2.5 billion annually. Continued success of this industry requires managing manure in a way that protects water resources. This guide defines the unique aspects of managing manure as a phosphorus fertilizer source and provides practical information about management strategies to reduce phosphorus losses from your farm.John A.

Phosphorus best management practices for biosolids and other organic residuals

AGRICULTURALMU GuidePUBLISHED BY MU EXTENSION, UNIVERSITY OF MISSOURI-COLUMBIASoil and Fertilizer ManagementThe objective of this guide is to update the recommended practices for managing phosphorus in biosolids to reflect these recent advances. Many of the recommendations for animal manure apply to other biosolids because of the similarities between animal manure and biosolids. Other publications (see the suggested reading list at the end of this guide) describe phosphorus loss processes from agricultural land and the impact of phosphorus on water quality. These guides provide more in-depth descriptions of the key concepts of phosphorus loss and management. This guide will focus on the recommended practices for managing phosphorus with particular attention to the unique recommendations for biosolids.John A.

Agricultural phosphorus and water quality

PUBLISHED BY MU EXTENSION, UNIVERSITY OF MISSOURI-COLUMBIAAGRICULTURALMU GuideSoil and Fertilizer ManagementWe value clean water for many reasons. We depend on lakes and streams for drinking water and recreation. Wildlife depends on habitats created by healthy streams, wetlands and lakes. There is strong support in both rural and urban communities for efforts to maintain and improve water quality. Water quality has declined in some parts of Missouri in the 1990s. The effect of agriculture -- particularly the effect of phosphorus from agriculture -- in surface water quality has become a focal point for controversy. Does phosphorus reduce water quality? Is the problem nitrogen or phosphorus? What fields and practices cause high phosphorus in agricultural runoff? How can farmers protect our water quality from excess phosphorus?

Calculating the value of manure as a fertilizer source

The work sheet in this guide determines the value of manure only as a nutrient source, similar to commercial chemical fertilizers, regardless of its other positive or negative attributes. Actual economic value of manure must be negotiated between the manure seller and the buyer.Ray Massey (Extension Professor, Commercial Agriculture Program), John Lory (Extension Associate Professor, Commercial Agriculture Program)Reviewed November 2018 -- websit
