Managing N loss risks – Chris Dowling
Practical N management can minimise the economic impact of N loss events. Chris Dowling from Back Paddock Company presented at the Bellata Update.
Nitrogen application – Richard Daniel
The rate of nitrogen application drove yield and grain quality in trials conducted by Northern Grower Alliance (NGA). Neither timing of N application or physical incorporation of N fertiliser changed outcomes. Richard Daniel presented at the Goondiwindi, Bellata and Condamine Updates.
High N strategies for canola – Maurice Street
The optimal rates of N fertiliser for canola may be higher than traditionally thought. High N rates may benefit subsequent wheat crops. Maurice Street from Grains Orana Alliance (GOA) presented at the Dubbo Update.
Nutrients from stubble – Bhupinder Pal Singh
Stubbles can be a source of nutrients. Incorporated into soil, canola residues provide more N, P and S than wheat residues. Nutrient supply from soil organic matter also increased following tillage. NSW DPI researcher Bhupinder Pal Singh presented at the Dubbo and Wagga Wagga Updates.
Wet season 2016 – Rob Norton
Getting a handle on the current nitrogen status of paddocks is important. ANZ IPNI’s Rob Norton presented in Adelaide, Wagga Wagga, Bendigo and Rupanyup.
NUE with mid-row banding – Graeme Sandral
Mid-row banding urea at sowing was more profitable and efficient than other N application methods. NSW DPI’s Graeme Sandral presented at Wagga Wagga.
Other talks related to N management:
- Challenges and opportunities for continuous cropping systems. Continuous cropping (without pasture) can be sustained for decades. More N fertiliser is needed, even with grain legume rotations.
- The key drivers of high-end irrigated canola yields. Increasing the N rate above 150kg N/ha increased grain yield, decreased grain oil content and increased crop lodging.
