Crop Nutrition

Webinar: Look back on 2017 to have the best crack at 2018

What should you be thinking about for crop nutrition in 2018? The 2017 cropping season has been a mixed bag across Australia’s grain growing regions. There are some poor crops and some very good crops. For advisors, site-specific thinking could be even more important than usual next year. Join ExtensionAUS […]

How effective are high Nitrogen rates for canola – wheat rotations?

High nitrogen (N) fertiliser rates can have long-lasting yield effects in canola-wheat rotations. Since 2010, Grain Orana Alliance has looked at yield and oil responses in canola to increased nitrogen (N) rates. Yield increases often continued well beyond N rates that had been thought reasonable. There’s a risk of applying […]

What to do with a failed crop

Failed crops can still be an asset to the farm. This year many areas are facing the results of not enough rain. Severe frosts have hit some crops hard too. Failed crops are caused by weather, weeds, pests and disease. Legumes can fail when growers don’t use inoculants or wait […]

How is extension for crop nutrition evolving?

Over 7000 people engaged with the MPCN Northern Region program in 2012 – 2015. The More Profit for Crop Nutrition (MPCN) program aimed to improve returns from fertiliser. The program funded research and extension on soil and crop nutrition. The e-Extension and Training projects integrated the latest advice. Growers and […]

Frost damage and copper deficiency just look similar

Crop damage caused by frost looks a lot like copper deficiency. Leaf damage extends back from the tip of the leaf. Damage to seed heads can be easily confused too. Other than similar symptoms, there’s little evidence yet to link frost and copper deficiency. The location of damage can help […]

All in the ebook – what advisors and growers wanted to know

We’ve created an ebook! Local crop nutrition strategies, informed by recent research, are what we aim for.  Leading researchers toured eastern Australia in 2016 to speak at on-farm workshops. Detailed discussions on each day helped bridge local needs and new science. We published a string of articles in 2016 to […]

How good are in-crop mineralisation predictions?

Crops may source much of their nitrogen (N) from in-crop mineralisation (ICM) of soil organic matter. Of total crop N at harvest, an estimated average 63% came from ICM in a recent Victorian study. Total crop N includes grain, straw and roots. Root N is about 10% of grain and […]

Can you host a research trial in a nutrient deficient paddock?

Do you want to help with crop nutrition research? One of the GRDC’s latest research projects (UQ00082) needs nutrient deficient trial sites. The trial sites will help develop guidelines for nitrogen (N), phosphorus (P), potassium (K) and sulfur (S) for broad-leaved crops in eastern Australia.   For cereals, we know […]

Our top picks from the fertiliser industry conference

New science topped the agenda at the 2017 Australian Fertilizer Industry Conference. Fertilizer Australia hosted the conference in Torquay, Victoria. Of the many presentations, the following two papers are relevant to Australian growers and crop nutritionists. Phosphorus and soil biology Dr Cassandra Schefe works with Monash University. Her research investigates microbe […]
