Mechanistic understanding of the mode of action of novel soil reengineering methods for complex chemical and physical constraints

Full description

Six grower groups have identified priority soil constraints and soils to be included in this project. Using predominantly glasshouse studies, the effectiveness of novel amelioration methods will be evaluated in these soils, relative to the current industry best practice methods. This work will therefore set an unconstrained benchmark of soil performance and will identify successful options for future field studies.
The project will determine the mode of action of the amelioration methods enabling CRC researchers to optimise source material and/or the development of new products to improve efficiency of amelioration and will also inform effective application technologies. Many currently used surface applied ameliorants have little effect lower in the profile where subsoils constraints exist. This project will quantify the benefit of ameliorating these constraints. The data produced during these studies will input into the development of Decision Support Systems produced within the CRC. Therefore the project services researchers, grower groups and their members and possible industry stakeholders interested in development of new products.
