Timely Information

McCaw Seeds keeps you up to date every step of the way.
 
Growers and merchants receive a comprehensive report detailing the weight of seed delivered into store, its moisture, and in the case of ryegrass, an estimation of the expected dressing loss. Once processing is complete, you'll receive a comprehensive report detailing: ​

  • Clean seed tonnage 

  • Dressing loss percentage 

  • A comparison of your dressing results against similar seed lines processed over the previous 12 months 

 
This unique reporting provides valuable benchmarking information, giving growers greater insight into the performance of their crop and helping inform future management decisions. 

Customer Focused Service

Our customers are at the centre of everything we do.
 
We therefore maintain an open-door policy, welcoming growers to inspect their seed throughout the cleaning process and to discuss results directly with our team.
