NVZ Action Programme changes

NVZ Action Programme changes

Wednesday, February 8, 2012

Mandatory changes to the NVZ Action Programme came into force on the 1st January 2012 regarding the Nmax limit for grassland and the livestock manure nitrogen efficiency values, which must be used when assessing compliance with the Nmax limits.

These new changes mean that the Nmax limit for grassland reduced from 330 to 300 kg N/ha. Livestock manure nitrogen efficiency values that must be used in the Nmax compliance calculation have increased, meaning that more of the nitrogen from applied livestock manures will now be considered as available for crop uptake. This will reduce the potential amount of additional manufactured fertiliser that can then be applied.

Fertiliser planning tool PLANET has a facility that calculates compliance with the Nmax limit for each Nmax crop type grown on the farm. This facility helps NVZ compliant planning of nitrogen use at the start of the growing season, and helps show compliance with the Nmax rule at the end of the season.

The current version of PLANET is being updated to include these mandatory changes, and a new version will be released in 2012.
