OpenHectare

Trusted sources

Answers you can trace back to the source.

Good farm advice should be checkable. Every OpenHectare answer is built from extension research, peer-reviewed science, and grower organisations — not opinions or guesswork.

When you get an answer, it points to the sources behind it. You can read the original material yourself and decide if it fits your paddock, your season, and your situation.

If the evidence isn't strong enough to give a clear answer, we say so plainly instead of guessing.

Sources a farmer already checks.

Answers use the town and state you enter, and your crop. They are not a county forecast. When a question needs it, they also draw on public research from Australia, the UK, and elsewhere.
