Fertiliser blending (bulk blending) is a technical process that offers a customised balance by adjusting fertiliser inputs to crop requirements.
In the right proportion, the blend must provide:
- Major nutrients: nitrogen (N), phosphorus (P), potassium (K);
- Secondary nutrients: calcium (Ca), sulphur (S), magnesium (Mg), sodium (Na);
- Micro-nutrients: iron (Fe), manganese (Mn), molybdenum (Mo), copper (Cu), boron (B), zinc (Zn), cobalt (Co).
AFCOME’s members are French pioneers in fertiliser blending.
AFCOME keeps up with the best available techniques thanks to its long-standing collaboration with international specialists from the USA, Canada and UK, the European Fertilizer Blenders Association (EFBA), technical centres (CEMAGREF) and universities (GEMBLOUX).
AFCOME members have shared their expertise by producing two reference documents that are authoritative in their field and are periodically updated:
- The Handbook of Solid Fertilizer Blending: Code of Good Practice for Quality, produced in collaboration with EFBA (2nd French edition: 2005 – 2nd English and German edition: 2007).
- The Guide on the Principal Rules for Fertilizer Marketing produced by AFCOME’s Regulatory Commission (October 2013).
