Reaping has begun with Port Pirie receiving the first load of grain delivered in Viterra's South Australian network for the third year running.
Mambray Creek grower Ben Bussenschutt made the delivery on Tuesday on behalf of the Bussenschutt family for the 2019-20 season with a load of Spartacus barley.
Port Pirie was again the first destination for grain in the company's network of 67 receival sites around the state.
Mr Bussenschutt said his family has been the first to deliver to Viterra at the start of harvest on more than one occasion now - the last time was in 2017-18.
"Spartacus grows quite quickly and we usually seed at Mambray Creek from mid-April to get some early rain before starting to seed at our Paskeville property," he said.
Viterra operations manager Michael Hill said the timing of the warmer weather in the upper Yorke Peninsula had helped finish off the crops earlier than in other areas.
"All our sites around the network are prepared and ready to go when growers throughout the state start harvesting," he said.
"In the lead-up to harvest, we have worked with growers to understand their needs to ensure that we are providing a service to them that is both valuable and efficient.
"That includes making significant investments in our supply chain with about $40 million directed each year to where we can provide the greatest value to growers during harvest."
Mr Hill said the business looked for ways to pass efficiencies back to growers.
"This harvest we have added barley dynamic binning after feedback from growers and the success of wheat dynamic binning last year which delivered about $6 million in value to growers," he said.
"Dynamic binning provides growers with the potential to access a higher grade for loads that are just outside of receival standards.
"We have gained efficiencies in grain transportation and passed these on to growers through our Export Select rates which at most of our major sites have decreased or stayed the same compared with 2018-19."
"Our main focus is to operate an efficient, cost- effective and sustainable supply chain and we will work with growers during harvest to continue doing so."
