The European Union Water Framework Directive requires governments to set water quality objectives based on good ecological
status. This includes specific requirements to control diffuse pollution. Diffuse phosphorous (P) pollution plays a pivotal role in
influencing water quality with losses of P associated with soil particles often linked to soil erosion. The Mitigation Options for
Phosphorus and Sediment (MOPS) project, using three case study sites, is investigating the cost effectiveness of specific control
measures in terms of mitigating sediment and P loss from combinable crops. The analysis is conducted at the farm level using a
simple spreadsheet model. Further development of the model will allow the results to be extrapolated to generic regional...

NO-TILL TECHNOLOGY: IMPACTS ON FARM INCOME, ENERGY USE AND
GROUNDWATER DEPLETION IN THE PLAINS

Rapidly rising fuel costs for irrigation and tillage, combined with groundwater depletion confront producers in the Great Plains.
Maintaining profits while production costs escalate and water levels decline emphasizes the need to increase water and energy use
efficiency. A linear programming analysis for a ten-year period comparing conventional tillage practices with no-till practices
based on an irrigated wheat/ no-till feedgrain /fallow crop rotation indicates no-till increases both water and energy use efficiency.
Returns to land, management, and risk are substantially higher using no-till practices
