AFFIRM and Alberta MMP Software

Crop Information

The planned rotation over the course of the MMP along with expected yields for each crop and year is entered using the ‘Crops’ window (Figure 7.2.13). If soil analysis information is unavailable MMP will use default N recommendations for the crop based on yield and soil zone.

Default fertilizer recommendations can be overridden by entering customized recommendations appearing on a soil analysis report or from some other source. The program also provides space to identify the source of the custom recommendations.

To account for N contributed by legume N-fixation, there is a column that allows entering the percentage of a forage stand made up of legumes.
