Determining the vertical redistribution of MaP and MiP in agricultural soils under different edaphic conditions and investigating the impact of MaP on soil hydraulic properties. More specifically we will (1) determine the vertical redistribution along the soil profile, due to percolation, tillage and bioturbation; (2) analyse the distribution of MiPs on different aggregate sizes and determine the stabilization of MiP against leaching; and (3) determine the effect of MaP on soil hydraulic properties, which potentially affect leaching and surface runoff generation.
