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 […]

Tillage increases P accessibility

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 […]

What to do about fertiliser after a tough year

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
Nitrogen (N)

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 […]
