Phosphorus Balance Calculator (XLS 15KB)

This phosphorus (P) calculator is a simple spreadsheet that allows farmers and their crop advisors to input actual yields and applied P fertilizer rates used in the crop rotation.

The P balance is automatically calculated using P removal book values from the Manitoba Soil Fertility Guide, to show if soils are being depleted, maintained or built with P.

It also enables the evaluation of manure application in the rotation as an alternative to maintaining soil P levels.
