The challenge of managing soil acidity through tailored lime treatments continues to be an international dilemma, as two Western Australian scientists discovered during a recent study tour of South
The effect of mechanical incorporation of different lime rates on crop yield and subsurface pH was observed four seasons after application.
Mechanical incorporation of different lime rates using offset disc, Grizzly Tiny offsets® and deep ripping treatments were tested.
Amelioration of soil pH in poor soil patches in paddocks was tested using lime application and deep ripping treatments.
Mechanical incorporation of different lime rates using Grizzly Tiny offset® plough, deep ripping and cultivator points were tested.
Detailed soil acidity mapping and analysis by Western Australian researchers has featured in a Food and Agriculture Organisation (FAO) of the United Nations report on the world’s soil resources.
As celebrations to commemorate World Soil Day are held, the Department of Agriculture and Food is continuing its work to overcome one of the greatest threats to the State’s agricultural land – soil
Using tillage to incorporate lime improves the rates of reaction and increases subsurface pH sooner than spreading lime on the surface alone.
Soil acidity overwhemingly causes aluminium toxicity in Western Australia.
Improving water use efficiency is a key requirement to grow more grain. Soil compaction and other soil constraints like subsoil acidity or water repellence restrict plant roots’ ability to access...
