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.
Looking closer at the roots

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 […]

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 […]
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 […]
