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 […]

What is the value of fixed N?

How much N does a legume crop give a following cereal crop? A review looked at the $ value of Nitrogen (N) fixed by legume crops (chickpeas or lupins) to a following cereal crop around Australia. This work will be presented at the Agronomy Conference in September 2015 in Hobart. […]

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 […]

Using legumes to reduce N losses

Mike Bell from the University of Queensland and QAAFI talks about the role of legumes in reducing nitrogen fertliser inputs and reducing the risk of nitrogen losses. The video was taken at the National Soils Conference held in Melbourne in November 2014. For more information: Denitrification the latest chapter in […]

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.   Further information GRDC: Deep […]

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. Further information Proceedings of the Soil Science Australia National Soil […]

Summer Crop Nutrition 2014 / 2015

After a hot finish to the winter crop season, the opportunity for summer crops is now upon us. Fertilisers can account for up to 40% of the variable costs of growing a crop. Hence it is well worth investing money in accurate soil testing and agronomic advice to help balance […]

A new way of looking at P nutrition

Mike Bell from QAAFI and the University of Queensland presented to Advisers at the GRDC Update at Coonabarabran. In this video Mike talks about a new way of looking at P nutrition. For the full paper visit the GRDC website.

Time for an N-Rich test strip

To reduce some of the uncertainty about in-crop nitrogen, Dr Rob Norton from the International Plant Nutrition Institute suggests using an N-Rich strip applied either presowing or soon after sowing. If responses can be seen later in the season where the extra N was applied, it is a good indication […]
