Crop Nutrition

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. Scott and Jillian Vaessen farm at Tabbita in southern NSW. […]

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. Trial set up Data collection points […]

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 […]

Nutrient strategies for 2018

Given the very patchy 2017 season, how shall we approach crop nutrition in 2018?  In November 2017, Rob Norton gave a webinar for ExtensionAUS Crop Nutrition on this topic. Rob is the Regional Director for the International Plant Nutrition Institute (IPNI). The main crop nutrition strategies Rob suggested: do soil […]

What happens in the year after a hayed-off crop?

A hayed-off crop can make estimating available nitrogen (N) trickier than usual. Deep N testing is the best way to assess N resources.Estimates and actual results from deep soil testing were very different in recent research by Birchip Cropping Group. After haying off there’s potential yield benefit next season from leftover […]

Help Australia day mungbeans get what they need

Some rain around Australia’s northern region saw some last minute mungbean crops go in. The GRDC Mungbean Grownotes suggests we base fertiliser recommendations on: soil test results fallow length yield potential paddock history. That’s comprehensive, but with an opportunity crop there’s not always the chance to cover all the bases. […]

What is the fate of nitrogen fertiliser?

Do you know the fate of nitrogen (N) fertiliser that’s applied to cropping paddocks?  How much ends up in the crop, soil or lost? Victorian researchers have been working with a traceable N fertiliser to find out. The standard assumption is the crop takes up half the fertiliser N in […]
