Manage pH for profit

Video: Craig Scanlan from Department of Agriculture and Food, Western Australia talks about the interactions between nutrition and soil acidity.
Research in Western Australia has been looking into the interactions between Phosphorus (P) fertiliser rates and soil pH given that most West Australian cropping soils have good soil P reserves but […]

SPOTLIGHT: Fertiliser calculator

The Department of Agriculture and Food, Western Australia (DAFWA) have recently upgraded their online fertiliser calculator tool. The free calculator is designed to guide decisions on which fertilisers represent the best value for money while meeting crop nutrient requirements.

The calculator allows comparisons of 1500 commercially available fertiliser products for their […]

No-till soils and strategic tillage

NSW DPI’s Mark Conyers is working on getting the information we need to make decisions on striking a balance between the benefits of conservation farming, and the rationale for strategic tillage to manage issues like acidity, weeds, pests and crop diseases.

One emerging issue is how well conventional soil sampling is able […]

Reducing nitrous oxide emissions from dryland grains soils

Graeme Schwenke from NSW DPI talks about reducing nitrous oxide emissions from dryland grains soils in northern NSW.  Nitrification inhibitors substantially reduced nitrous oxide emissions and other N losses when heavy rains and waterlogging follow fertiliser application. Splitting N applications and alternate fertiliser forms were also looked at. The video […]

Understanding & managing multiple nutrient deficiency

Mike Bell from the University of Queensland and QAAFI talks about the increasing incidence they are seeing of soils with multiple nutrient problems and the implications on fertiliser management strategies. The video was taken at the National Soils Conference held in Melbourne in November 2014.

Carbon credits from fertilizer management

Cotton farmers could soon add value to their nitrogen fertilizer management by earning income in a similar process to graziers under the Emissions Reduction Fund (ERF) that recently passed through the Senate.
Emissions reduction methods set out the rules for estimating emissions reductions from different activities, and ensure that emissions reductions are […]

Crop nutrition in soils with added clay

David Hall from DAFWA says adding clays to sandy soils can add significant Potassium and Phosphorous, as well as improve the nutrient holding capacity of the soil.  Recorded at the National Soil Science conference at the Melbourne Cricket Ground, November 2014.

Grain analysis for nutrient strategy

Analysis of freshly harvested grain can:

– show if that crop had a hidden hunger that may have limited yield
– document the degree of a known deficiency
– confirm its suitability to use as seed
– inform future crop nutrition strategy for the paddock.

Tissue testing of grain is valuable for assessing trace element […]
