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 […]

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 […]

Starter and residual P give strong early vigour in the north

Aerial photograph of starter and deep P trial site plots

This season, starter phosphorus (P) is producing strong early crop vigour. Deep P placement effects and the response to starter P are being documented at a long term monitoring site at Terry Hie Hie, in far north New South Wales.   The trial site compares plots with different rates of […]

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 […]

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 […]

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, […]

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? Join us for […]

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 […]

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 […]
