Key messages

• Dual purpose winter crops can help fill the autumn–winter feed gap
• While there is currently a full moisture profile, a dry topsoil and potentially dry autumn may impact establishment
• Be mindful of soil temperature and available soil moisture when sowing early (February–March)

The ups and downs of harvest (and running a property every other day of the year) can be extremely taxing. Managing stress is crucial to avoiding burning out mentally and physically or creating long term health issues.

Key Messages: 

• Each day is different – some days will run more smoothly than others so be aware of this and know when to take a break, switch paddocks or call it a day. 

• Try to think rationally and not over think things. Discuss options openly with your harvest staff. 

• Share the responsibility with others and delegate tasks when possible.

This season is testing the resilience and patience of farmers in our region and while harvest is currently very stop, start and erratic, it is important to keep safety at the forefront. 

Key Messages

• Pulse crops are under pressure due to current wet conditions and disease
• Brown or green manuring pulse crops may be an option this spring 
• Brown/green manuring can increase soil nitrogen, provide weed control options, help conserve moisture & improve soil structure and improve subsequent crop gross margins.

Perhaps trafficability has created difficulties with fungicide application and disease management has become problematic in your pulse crop. Or maybe specific weed issues have recently come into focus?

Key Messages

• Stubble retention has many benefits for soil health, can improve soil moisture and help maintain soil organic carbon levels
• Different methods of sowing and equipment result in different thresholds for change in terms of maximum stubble load that can be retained
• If full stubble retention is not feasible due to machinery, weeds or disease constraints, there are other options such as shallow incorporation, slashing straw or cutting short at harvest which can reduce the frequency of burning

Benefits of Stubble Retention

Retaining stubble can reduce the impacts of soil erosion. At least 70 per cent ground cover minimises water erosion risk and 50 per cent ground cover minimises wind erosion risk. Stubble height should be at least one-third of the width of crop rows. In general, the shelter provided by a barrier is approximately three times its height; 10 cm tall stubble will protect the adjacent 30 cm of topsoil.
