Soil testing the key to fertiliser savings.. According to the Crop Nutrition Fact Sheet published recently by the Grains Research and Development Corporation (GRDC), results from more than 100,000 recent soil tests in the south-west of WA showed that most growers are operating at or above the soil P levels required... If the tests show that soil P status is sufficient, there may be an opportunity for growers to save money on P fertiliser by cutting back to a maintenance rate...

Access to at least 60cm of subsoil moisture is a must if farmers are considering planting mung beans as a break crop this summer... "Their ability to fit into a short period of growing time is legendary," he said... Mr McIntosh urged farmers to do their research before planting, ensuring they have stored sub-soil moisture, and checking whether their soils have any constraints such as sodium or chloride, or any hard pans that may restrict root development...

Subsoil manuring comes of age in HRZ.. "What we end up getting after subsoil manuring is a larger bucket size and soil capable of holding three times its original capacity of plant-available water, which can be stored deep in the profile to be used in the spring grain-fill period achieving much higher water use efficiency.".. While results are still inconclusive as to which manure or organic matter might be best to use, Dr Peries says they do need to find a material that is more abundantly available should the popularity of subsoil manuring increase...

Crop roots push deeper after lime.. Tony White and his family have increased their wheat yields by applying 2.5 to 3.0 tonnes per hectare of lime and then hiring spading and mouldboard ploughing contractors to push the ameliorant into acidic subsoils on their farm near Miling, Western Australia... For the past two seasons, Tony has harvested more grain by doubling his usual rate of lime and using spading and mouldboard ploughing to really drive the ameliorant into the subsoil...
