Trials looking at placing nitrogen fertiliser into the soil have shown some different outcomes. In the southern region adding mid-row banding (MRB) to the crop nutrition toolkit looks interesting. A trial showed modest yield gains and better fertiliser uptake. In the northern region, rate looks more important than how nitrogen […]
Tillage can redistribute phosphorus (P) within the top 10 cm of the soil. P often becomes concentrated at the soil surface, especially in no-till paddocks. Getting P deeper into the soil is important in dry seasons when the active root zones are deeper.
Trials tested the response of wheat to P […]
Take a look at our five most popular articles and videos from 2017.
This year we published 60 articles on www.extensionAUS/Crop Nutrition These articles covered many different aspects of crop nutrition in the Australian grains industry.
These articles were prepared with and reviewed by, members of our Community of Practice, Australia’s […]
Balancing legume N with fertiliser inputs can be tricky. Legumes can affect soil N dynamics in unexpected ways. For example, chickpeas grown in low N soil can fix a large amount of N. But in high N soils, chickpeas use the soil N and fix less from the atmosphere. They […]
Good P supply through the root zone can improve crop growth. Placing some P fertiliser deeper into cropping soils can help supply the needs of maturing crops. Where subsoils are low in P, deep placing P can deliver yield gains.

After a year with failed crops due to drought, it’s not ‘business as usual’ for the next season’s inputs. Some fertiliser nutrients can remain in the soil if they weren’t taken up by the crop. Demand for other nutrients can increase after drought.
Key nutrients after a tough year
Stubbles can be a source of nutrients for next season. Different crops grown under different conditions have varying amounts of nutrients in their stubbles. Nutrient budgets can consider the amount and type of stubble.
How much stubble?
Stubble loads can be estimated from grain yield and the amount of growth. For cereals, […]
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.

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 […]
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 […]
