Surface Runoff Characteristics From Claypan Soil In Southeastern Kansas Receiving Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski

Kansas Agricultural Experiment Station Research Reports

Preliminary results show that two-year average total nitrogen (N) runoff losses and ortho-phosphorus (P) and total P runoff losses in the second year were greater with N-based turkey litter/no-till applications than P-based turkey litter or fertilizer-only applications. Incorporation of turkey litter applied based on N requirements resulted in N and P losses that did not differ from losses from P-based or fertilizer-only treatments. Chemical and statistical analyses of third-year samples will allow for final results and interpretation.

Saving The Catchments Of Albany's Harbours, Ashley Prout

Journal of the Department of Agriculture, Western Australia, Series 4

Fertiliser, particularly phosphorus, running off farm land is a major source of nutrient entering Albany's harbours. Oyster Harbour, which has a large rural catchment, is especially at risk.

The build-up in nutrients in the harbours has caused nuisance algal growth since the early 1970s and subseuent death of more than half the seagrass beds, which are vital to the areas marine life.

The Department of Agriculture, at the request of the Environmental protection Authority, has developed and promoted catchment management plans that enable rural land holders to reduce the amount of run-off into the harbours without necessarily sacrificing farm productivity. …
