Abstract
The work described under this project covers field work on
phosphorus(P) loss from soil to water under field conditions. In
addition two International Workshops on P loss to water, held in
Ireland in 1995 and 1998, are also covered under this project. The
results indicate that P loss to water is a complex process and it is
influenced by a number of factors, including hydrology of the soil,
rates and timing of P application and soil P levels. Most work on this
subject indicates that there is a positive relationship between soil test
P levels and P loss to water. There is need for further work to
establish the relative contribution of the different variables involved in
P loss from soil to water for different soils and farming conditions.
This should help provide answers to the most sustainable methods to
minimise losses of P to water and ensure that agricultural production
is compatible with good water quality.
