How are you growing a great break crop?

The yields of ‘break crops’ are more important to farm incomes with higher prices for some non-cereal crops.  In 2017, 22.5 million hectares were sown to winter crops. Over 20% – 4.7 million ha – were non-cereals. In the period leading up until 2011, break crops were around 14% of […]

How to manage nitrogen in no-till residues

Crop residues influence the supply and uptake of nitrogen (N). In the long term, residues will improve soil fertility. Stubbles can immobilise soil N as they break down. Moisture makes a big difference to the rate of stubble decomposition and mineralisation of nitrogen in the soil.

Looking for better yields from sandy soils

Sandy soils can show poor water use by crops. There are around 5 million hectares of sandy soils in Australia’s low-medium rainfall southern region. Growers see poor crop performance even with residual subsoil water at harvest.
To date, options to improve sandy soils are either:

Mitigation: lower-cost, annual activities.  Techniques include […]

Working on the yield gap to boost profit for HRZ growers

A comprehensive technical report explores the yield gap typical in commercial wheat and canola crops in the high rainfall zone (HRZ) of southern Australia. A previous report concluded that the yield gap was due to insufficient fertiliser being applied to achieve potential yield. The main barrier to supplying sufficient nutrients […]

How to review last season’s crop nutrition decisions with Chris Dowling

You might know how much you spent on fertiliser last season, but do you know if it was a good investment? Review at the end of the season can answer that question. Do you know how to assess how well last season’s crop nutrition management shaped up?
In this webinar presented […]

Workshops unearth promising tactics on the farm

More Profit from Crop Nutrition (MPCN) held a workshop at Keytah, near Moree in north-western NSW. Nick Gillingham manages Sundown Pastoral Company‘s cropping operations on the farm. Some issues with management implications for Nick at Keytah were discussed at the workshop.

Compaction and options to remediate
Phosphorus – removal rates, not banding […]

Latest expert advice on deep banded fertiliser

Deep banding of phosphorus (P) and potassium (K) fertilisers has shown promising yield responses in some settings, but not in others. Deep-banding trials across Queensland and New South Wales have shown that banding rarely reduces crop yield, but it doesn’t always lead to profitable yield increases.
Some of the variability in […]

The best frost tactics for 3 key nutrients

Crop nutrition can affect crop responses to frost, so crop nutrition strategies need to be different for frost prone paddocks.
Identify frost prone areas on farms, and aim to maximise profit rather than yield in those areas.
Copper
Tissue test to understand copper levels across the farm and don’t run with deficient levels […]

How to review Nitrogen nutrition at 3 timely points in the season

John Angus is a researcher with the CSIRO and a mixed enterprise farmer in southern NSW. At the 2016 GRDC research updates John reported on a three stage process to make strategic decisions about Nitrogen (N) nutrition through the season for dryland farmers.
Stage 1 – Prior to sowing
Prepare a Nitrogen […]
