Nutrient strategies for 2018

Given the very patchy 2017 season, how shall we approach crop nutrition in 2018?  In November 2017, Rob Norton gave a webinar for ExtensionAUS Crop Nutrition on this topic. Rob is the Regional Director for the International Plant Nutrition Institute (IPNI).
The main crop nutrition strategies Rob suggested:

do soil tests
use N […]

Help Australia day mungbeans get what they need

Mungbeans growing in cereal stubble. GRDC
Some rain around Australia’s northern region saw some last minute mungbean crops go in.
The GRDC Mungbean Grownotes suggests we base fertiliser recommendations on:

soil test results
fallow length
yield potential
paddock history.

That’s comprehensive, but with an opportunity crop there’s not always the chance to cover all the bases. […]

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 […]

Rob Norton recognised for excellence at fertiliser conference

Rob Norton

Congratulations to Rob Norton, who last night received an award recognising his long contribution to the Fertilizer industry, from Fertilizer Australia. Rob, the Regional Director of the International Plant Nutrition Institute (IPNI), is also the chair of extensionAUS’s crop nutrition Community of Practice. The award was presented at the conference dinner for the 2017 […]

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.
Nathan Craig was involved […]

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 […]
