What is MANNER-NPK ?

MANNER-NPK is a practical software tool that provides farmers and advisers with a quick estimate of crop available nitrogen, phosphate and potash supply from applications of organic manure. MANNER-NPK is applicable in England, Wales,Scotland and Northern Ireland

MANNER (MANure Nitrogen Evaluation Routine) version 3.0 was released in 2000. The new version of MANNER-NPK (due for release in early 2013) incorporates new research, improved usability and new features.

MANNER-NPK needs only a few simple inputs to run, which include;

  • Farm and field details, i.e. location, soil type, crop type.
  • Manure type and nutrient content. The results of laboratory analysis can be entered if available, or alternatively MANNER-NPK will use default nutrient analysis for the selected organic manure type.
  • Manure application details, i.e. application rate, application method and soil incorporation. Details of up to 3 manure applications to a single crop/field can be added

MANNER-NPK estimates the fate of organic manure N following land application, based on the latest research information on the mineralisation of manure organic N, and N losses via ammonia volatilisation, denitrification and nitrate leaching. The total N applied and an estimate of crop available N in the current cropping year and in the year following manure application is given.

MANNER-NPK also calculates the amount of total and available P2O5 and K2O applied, and the amount of total SO3 and MgO applied. The potential financial value of the manure application(s) in £/ha is calculated based on current fertiliser prices (which can be edited). MANNER-NPK generates a 1 page report summarising all input and output information, which can be saved or printed.

MANNER-NPK includes NVZ warning messages which highlight potential breaches of the NVZ rules specific to England, Wales, Scotland or Northern Ireland. A library of relevant guidance documents is included.

The MANNER-NPK calculation engine is incorporated into the PLANET software. Therefore results from MANNER-NPK are compatible with the output of PLANET and with guidance in Defra’s Fertiliser Manual (RB209)/ SAC Technical Note on the application of bulky organic fertilisers (TN622).
