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.

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 […]

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

leaves showing damage and rolling of leaf tip

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 with […]
