| Project Abstract | Ireland employs the Morgan's soil P test to measure plant available P, for agronomic advise using a sampling depth of 10 cm, to rapidly estimate the quantity of plant-available P in soil. The interpretation of soil test results for P has focused on predicting the likelihood of a crop response to P added in fertilizers, manures or other soil amendments, rather than predicting the potential for P loss from fields to water. The objective of this research is to develop an environmental soil P test which reflects the process of P loss from soil to water in the field during rainfall events. The research will determine the effect of varying soil sample depths, employing different soil P extractants, and also an investigation into different solution to soil ratios. Field studies will also be conducted to determine the relationship between soil test P levels in soil and both dissolved reactive P and suspended solids in overland water. |
