Innovative approaches to managing subsoil acidity in the southern grain region |
Abstract |
“Innovative approaches to managing subsoil acidity in the southern grain region” was a national coordinated project funded by GRDC (DAN00206) to test whether aggressive application methods such as deep placement of lime and/or organic materials will achieve rapid changes to pH at depth. A series of lab incubation studies and soil column experiments have been conducted under controlled conditions to a) Compare the effectiveness of a range of inorganic and organic amendments, and their combinations, to ameliorate soil acidity; and b) Optimise the application rates and application depth in soil profiles to identify the most effective soil amendments. Four small plot field experiments and eight large-scale on-farm field experiments were conducted in southern NSW and north west Victoria to test optimum rates of the most effective soil amendments at various soil depths to validate their effectiveness under field conditions. The inorganic amendments tested include lime, dolomite, magnesium silicate (MgSi), calcium nitrate, reactive phosphate rock (RPR), gypsum etc. The organic amendments tested include plant residues/materials (such as lucerne hay, pea hay, cereal crop straw, garden composts), animal wastes (such as poultry litters, dairy compost, sheep manure) as well as biochar, biosolids and k-humates. |
