Subsoil Acidity

Innovative Approaches to Managing Subsoil Acidity Activity in the Southern Grain Region

Project Partners:  GRDC, FarmLink, NSW DPI
Project Code:  DAN 00206
Project Duration: 2015-2020
Project Location:  FarmLink Region


This project will investigate more aggressive ways, such as the deep placement of lime to the subsoil where it is most needed, with or without organic amendments to achieve more rapid changes to pH at depth. Other novel materials, such as calcium nitrate fertiliser, nano-lime and silicate-based materials, either separately or in combination, will be tested in different soils with difference crop species in both controlled environments and under field conditions. Detailed studies are essential to increase our understanding of these plant-soil interactions and the mechanisms involved.
