CBH Grain has closed its 2009-10 wheat harvest pool to Victorian and South Australian growers.

CBH grains manager for eastern Australia Chris Ayers said the pool was closed last Friday as the pool management committee was comfortable with volumes reached.

"We will continue to focus on protecting the pool equity with the aim to ensure we maximise returns for our pool participants," Mr Ayers said.

"Our harvest pool for wheat was well supported by South Australian growers again this harvest and it received strong interest in its first harvest open to Victorian growers."

Mr Ayers said the Victorian pool for Australian Premium White wheat had an estimated pool return of $252 a tonne.
