Test what when to help crop nutrition decisions?

Lab tests help advisors with fertiliser and soil amendment planning. Without lab tests, crop nutrition can be a ‘best guess’. Returns from fertiliser inputs might not be optimal. Yields could suffer.
Soil, plant tissue, and grain testing can guide crop nutrition throughout the season. Soil tests indicate crop available nutrient levels […]

Top up nutrients after a good year

Nutrients leave the paddock with the grain. A good yield means more nutrients go out and less remain in the soil. Some nutrients may need topping up to maintain yields.
How much topping up?
Different grains contain varying amounts of nutrients. The table below gives estimates of the nutrients removed in […]

Is nitrogen placement different north vs south?

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 […]

Top five in 2017

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 […]

How to account for stubble nutrients next season

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, […]

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 […]
