FARM exports and incomes are tipped to rebound strongly over the next year, mainly due to big crop harvests.

In its latest forecasts, the Australian Bureau of Agricultural and Resource Economics says farm exports are set to jump by 9 per cent to $30 billion in 2008-09.

Farm cash incomes are expected to be almost 19 per cent up at $11.2 billion.

Crop farmers are looking at a 24 per cent lift in export incomes with bumper harvests in prospect for most grains.

But grain prices are likely to ease, including a 10 per cent drop in wheat pool returns.

And ABARE warned that its forecasts also depended crucially on further spring rainfall.

For livestock farmers, improved seasonal conditions should see more herd re-building, fewer slaughters and lower production. Livestock exports are tipped to fall by 3 per cent.

Sheepmeat and beef producers can expect higher saleyard prices, but wool farmers are looking at sharp price slumps.
