The apparent net reduction in topsoil total P can be attributed to a combination of factors including cessation of grazing, decomposition of pasture residues, tree uptake, changes in organic matter and nutrient returns to soil under trees compared with grassland, and direct impacts of changes in the nature, distribution and activities of tree root systems compared with grassland. These findings confirm that afforestation of grassland has a major long-term impact on soil properties and processes.5 pagesen© The Authors and FLRCsoil phosphoruspastureplantation forestrysoil propertiesphosphorusConference Contribution - publishedANZSRC::0503 Soil Sciences2230-3944
