We hypothesise that the transfer of P from P sources, primarily the soil surface, into runoff in our study is an equilibrium reaction that is influenced by the equilibration time (a longer time results in a greater equilibration and hence a higher runoff P concentration) and the ratio of the volume of runoff water to the P source (the wider the ratio, the longer taken to achieve the equilibrium runoff P concentration).
The secondary objective of the study was to determine whether the particle size distribution of the organic erosion control blanket affects runoff, erosion, and vegetation establishment.
