The P & K calculator is an online calculator for estimating P and K fertilizer requirements for grassland and crops from the Fertilizer Association of Ireland.

This P and K calculator tool provides general guidelines for crop offtake and/or general agronomic advice for P and K application to grassland and arable crops in Ireland.

It is available online, or via the iOS and Android Smart Phone Apps.

**Please note that some users have had issues with installing the Android App, contact the Fertilizer Association if this is the case: info@fertilizer-assoc.ie**

It requires details of crop yield, grassland stocking rate, concentrate feed usage, soil test results, and slurry application to estimate chemical fertilizer P and K requirements.

All calculations are consistent with Best Practice Recommendations from Teagasc.
