How to keep bulk fertiliser deliveries safe

Bulk fertiliser deliveries can cause accidents and near misses. Overhead obstacles, unsafe access, and dumped product are potential hazards.
Fertiliser safety is everyone’s responsibility.  The Heavy Vehicle National Law (HVNL) will soon be amended to reflect this. The changes mean that every party in the supply chain – not just the […]

Nitrogen topical at 2018 GRDC Updates

Keep up with the latest research information on nitrogen. The following papers and key messages were presented at the GRDC Updates across Australia in February and March 2018.
Improving N efficiency using mid-row banding – Graeme Sandral
Mid-row banding urea at sowing provided a higher yield and profit response in wheat compared […]

Research into mid-row banding benefits continues

In 2016, Agriculture Victoria researcher Ashley Wallace conducted mid-row banding (MRB) trials in Victoria. These were part of the GRDC/Agriculture Victoria Regional Research Agronomist program.The trials compared MRB nitrogen fertiliser in-crop to other application methods. MRB is when fertiliser is applied in concentrated bands below the surface to every second […]

Use tissue tests to detect deficiencies

Micronutrients or trace elements are an essential part of crop nutrition. They are as important as the better-known macronutrients nitrogen, phosphorus and potassium. This was a key message on the southern tour of the MPCN II Roadshow in August 2016.

Nitrogen management key driver of WUE

The rate of nitrogen (N) fertiliser applied is the stand-out variable influencing water use efficiency (WUE) in wheat crops. This was the main finding in a four-year research trial in western Victoria. Ten variables accounted for a third of the WUE variation between sites.

Data collection points were set […]

New way to gauge nutrient status

Nutrient Rich Strips are not new in cropping. They are used to see if there is a clear growth response to an applied nutrient. But it is often hard to quantify the response and translate it into fertiliser rate recommendations. Some fertiliser advisors are using a new tool to address […]

Give seeds the best chance in a dry start – how to avoid fertiliser burn

Seeds can be damaged by fertiliser placed too close or at too high rates. Dry soils increase the risk of harm to germinating seeds from fertilisers. Take extra care with fertiliser and seed placement this year. The dry lead in to 2018 winter sowing means last year’s strategy might not […]

How to protect your grain – prevent contamination

There have been a few cases of Australian grain being contaminated with chemicals after harvest. The chemical ended up on the grain through using the same trucks to move treated fertiliser and transport grain.
About 15% of Australian cereal crops use fungicide treated fertilizer. The fungicide flutriafol controls certain fungal […]

Does incorporating lime boost fertiliser response?

Does addressing soil constraints change crop nutrition requirements? DAFWA researcher Craig Scanlan runs field trials in central and northern WA. The trials investigate links between soils, seasons and crop nutrition. The focus is how incorporating lime affects yield response to fertilisers. Soil mixing to treat water repellent soils is also […]
