Effective management of soil compaction, especially subsoil compaction, is important for improved water and nutrient use efficiency.
Liming to meet soil pH requirement using variable rate application will ensure it is targeted to where it is needed and not applied to areas that won’t benefit.
Spraying the face of a soil pit with universal pH indicator is a quick way of assessing the pH down your soil profile.
Root growth is slowed in acidic subsoil resulting in fewer roots, shallower roots, fewer fine roots and less branching. This has the potential to reduce water and nutrient use efficiency, depending on seasonal conditions.
A small decrease in soil pH can result in a large increase in acidity and aluminium.
Organic matter is increasingly important as an influence on water holding capacity as clay content declines.
