The EfR label is the guarantee for effective and responsible fertilizing

GPN Agriculture is launching a labelling system for its fertilizer and its services. This label is called "EfR" for Responsible Effectiveness. Meeting the criteria of sustainable development, responsible effectiveness is used to balance producer's profitability targets, and consumer expectations whilst respecting the environment.

For GPN Agriculture, sustainable development involves manufacturing quality fertilizers responsibly and supporting our customers.

The EFR label:

Effectiveness, because fertilizers bearing the label are rich in nitric nitrogen, providing the best nutrition for plants and the physical properties are optimized for an accurate application to guarantee dosage compliance.

Responsible, because fertilizers bearing the label have the best environmental record: low ammonia volatilization and small carbon footprint compared to urea-type fertilizers. They are produced in French factories having the highest standards in technology, particularly in terms of energy consumption.

Our EfR-labelled fertilizers:

GPN launched its new high-performance nitrogen fertilizer in September 2011: Ammo HP® :l'Ammo HP^®.

Our EfR-labelled tools

GPN Agriculture has developed several tools to assist you in managing and monitoring your nitrogen fertilizer.

The GPN Pilot^® :

management tool for fertilizing with nitrogen (link to specific page)

Faced with the quality requirements and environmental constraints, the GPN Pilot provides a solution. GPN Pilot is a useful, accurate and representative tool to come to an immediate decision for Nitrogen fertilization, all in easy to use and comfortable conditions.

• Concentrated technology in an upright and standing position
  
  GPN Pilot is a portable reflectometer: is the transfer of technologies used by satellites to be able to use them in a standing position. Measuring the reflectance of a vegetation cover determines the nitrogen nutrition level of a crop and therefore tests if the nitrogen fertilization needs to be adjusted.

• Make your decision in minutes
  
  With GPN Pilot, the measurement is quick, without complicated movements, the diagnosis is immediate (software is included in the device) and the decision to adjust the nitrogen dose is made without delay.

EfR Calculator

GPN Agriculture has developed a tool to quantify the performance variation between the Ammo HP ^® and urea by assessing, in particular, the economic impact of poor application.

The EfR calculator also gives an indication of the environmental impact depending on the type of fertilizer: it is the responsibility indicator.
This responsibility indicator takes into account ;

• the impact of an overdose linked to a heterogeneous application
• the energy balance and greenhouse gas emissions
• the volatilization of nitrogen as ammonia to the atmosphere.

The end result is that the farmer has an EfR report which assesses both technical economic effectiveness and his environmental responsibility.

Our actions

GPN has been the partner for effective and responsible fertilization for 25 years. So, GPN Agriculture carried out an experiment on the catchment at Auradé to study the impact of agricultural processes on the quality of surface waters.
