hard setting soil

Catalogue: GRDC Final Reports
The project team identified soil nutrient test kits, ground penetrating radar, remote electrical conductivity (EC) procedures and an instrumented, calibrated tine to measure soil strength as tools that offer value to growers in southern Australia... Several rapid soil tests may be used by growers to improve their knowledge of soil conditions... The use of a calibrated, instrumented tine while cultivating with a machine fitted with a precision GPS allows growers to diagnose and map compacted and hard setting soils (strong soils without structure).This information will allow growers to develop ripping regimes, controlled traffic practices and other amelioration procedures that precisely target these soil structure hazards...

Soil coring reveals to the farmer a fuller picture of the plant's exploration of its soil environment, a useful tool in crop management... Whilst measurement of parameters such as salt and sodicity, and knowing the physical condition of the soil, provide a guide to potential soil constraints, it is the plant that integrates all of the conditions it encounters and responds ... The shallow nutrients are regularly detected in the soil analyses of the standard (0-10cm) soil sample, but are often not available for plant uptake for long periods during the growing season...

Storing water is a challenge in our environment where evaporation potential is higher than rainfall in all months... Extra water safely stored in the soil through best management can be worth up to 500 kg/ha in dry years, although in some years there may be no improvement or lower yield if nutrition and diseases associated with stubble retention is not managed... Good rotations are a key part of the better water management game...
