To quantify losses of inorganic pollutants to the aqueous environment from application of livestock wastes - WA0503

Description
Although of potential value as a fertilizer, application of wastes to land frequently results in the loss of nitrogen, phosphorus and carbon compounds from the plant-soil system which can increase concentrations of nitrates, phosphates and biological oxygen demand (BOD) in surface or groundwaters. Such losses from soils can occur through leaching or lateral run-off but there is sparse information on the factors influencing the extent and rate of these events. This information is needed in relation to the type of waste, (slurry, farmyard manures, dirty water) soil and cropping circumstances in order to formulate sound guidelines for preventing water pollution.

The aim of this project is to devise a practical, minimum-cost means of managing livestock wastes so that these do not pollute water. Strategies are needed for efficiently utilising plant nutrients contained in wastes and for preventing their loss to the wider environment.
Objective
To collect information on the factors influencing the extent and rate of losses of N, P and C compounds from soils through leaching and lateral run-off, in relation to the type of waste, (slurry, farmyard manures, dirty water) soil and cropping circumstances in order to formulate sound guidelines for preventing water pollution.
