Welcome on this site on BEST AGRICULTURAL PRACTICES for reducing the EXCESS of NUTRIENTS
as described in the F2F Action Plan 2020 of the EU issued spring 2020 in the framework of the Green Deal.
The aim of this website is to provide farmers, advisors, suppliers and policymakers with practical information on how to reduce fertilizer use while maintaining or even improving yields. This is the relevant section of the F2Faction Plan that motivated us to create this website:

The Accountable Material Balance: a policy instrument we strongly recommend

We consider the AMB as the cornerstone of integrated nutrient management action plans. It is an effective modern policy instrument which contains sharp defined goals instead of means prescriptions. Learn about it from the videos below.

Smart Fertilization : best practice we recommend

This is feasible by the application of 4 R Nutrient Stewardship with plant nutrients from recycling or from renewable resources. This is what is named in the Netherlands Smart Fertilization and can be practiced with all types of technology, from low tech to high tech and with inorganic as well as with organic fertilizers.

Smart fertilization is placement at the right time, at the right rate, in the root zone of plants, of nutrients recovered from side streams or produced with renewable sources.
