Biosolids to overcome subsoils constraints in the Victorian grain growing soils

The aim of this project is to investigate the use of biosolids to overcome subsoil constraints in the high and low rainfall zones in Victorian grain growing regions: in brief,investigate whether subsoil physicochemical constraints that limit root growth and reduce water and nutrient-use efficiency can be overcome by using subsoil amelioration with pelletised T1C2 grade biosolidsdetermine whether subsoil amelioration with biosolids will have any adverse effects on plant availability of heavy metalsinvestigate whether microbial populations will be impacted from the application of biosolids into the subsoilsdetermine whether biosolids as a subsoil ameliorant can have any impacts on grain quality
