Sandy soils of the southern region - GRDC
Across the southern regions of Australia, growers have been observing ‘water left behind’ after growing crops in sandy soils. This poor crop water use is due to several constraints in sandy soils that present challenges for crop production.
Soil inversion by ploughing - GRDC
Mouldboard, disc or square ploughs can address surface soil constraints by inversion and burial but their performance can be affected by a range of factors.
Economics of deep ripping - GRDC
Deep ripping involves the loosening of soil at depths beyond what traditional cultivation methods achieve.
Diagnosing Sandy Soil Constraints: Nutrition (South-West) - GRDC
Crop nutrition for sandy soils.
Diagnosing Sandy Soil Constraints Water Repellence and pH (South-West) - GRDC
Measuring constrains on sands to inform management.
Diagnosing Sandy Soil Constraints: High Soil Strength (South-West) - GRDC
Measuring soil strength with a penetrometer. High soil strength can be caused by compaction and/or hard setting, and can severely limit root penetration, preventing access to moisture and nutrients at depth.
Soil Mixing by Spading: National - GRDC
Understanding the process of soil profile mixing with rotary spaders.
Inclusion Ripping Technology: National - GRDC
Understanding passive inclusion ripping.
Seeding Sandy Soils: National - GRDC
Managing water repellence at seeding: moisture access strategies
Ripping Technology: National - GRDC
Technology considerations for cost-effective subsoil loosening
Soil Wetter: National fact sheet - GRDC
Managing water repellence at seeding: soil wetting agents. Soil water repellence causing patchy and poor crop establishment depends upon seasonal conditions, but wetting agents can mitigate the risks.
Physical Soil Constraints fact sheet - GRDC
The villains of hard subsurface layers in sandy soils.
Paddock Practices: Practical remedies to target challenges of deep ripped soils - GRDC
Some growers experience poor crop establishment after sowing into deep ripped sandy soils, and press wheel design, steel drum rollers and different deep ripper and seeder tyne configurations are being investigated as possible solutions.
Paddock Practices: Chicken litter trials revealing sandy soil constraint improvement - GRDC
High-rate applications of chicken manure are showing positive signs of ameliorating sandy soils in trials on South Australia’s Yorke Peninsula.
