About

CampoCalc offers free calculators for growers, farm advisors and students: hydroponics, livestock, crops and land measurement.

How we build the calculators

• Every tool explains the formula it uses and shows a worked example.
• We cite technical sources (universities, research institutes and specialist guides).
• All calculations run on your phone or computer: we do not store the numbers you enter.
• Once you have opened the site, it works offline, which helps in places with poor signal.

Limitations

Results are reference estimates. They do not replace a product label, a soil test or the advice of an agronomist or veterinarian. If you find an error, let us know through the contact page.
