EFA Nitrogen Fixing Crops Seed


Nitrogen-fixing crops may be grown on their own in pure stands or may be mixed with other crops providing the nitrogen-fixing crops make up at least 51% of the plants in the ground.

  • The minimum area of nitrogen-fixing crops which can count as an EFA is 0.01 hectares.

  • Read the crop list to find out which nitrogen-fixing crops can count as an EFA.


Apart from the plant protection products restrictions, there are no specific restrictions on the use, location or inputs for other nitrogen-fixing crops, but farmers must follow the cross compliance rules on this land. To be eligible as EFA, nitrogen-fixing crops must be in the ground during the crop diversification period, from 1st of May to 30th of June.


Farmers growing EFA nitrogen-fixing crops must not use plant protection products on their crop for the full crop cycle from planting to harvest. This includes seed dressings. For farmers growing multi-annual nitrogen-fixing crops, like Lucerne for example, the ban on applying plant protection products applies from 1st January until 31st December unless a final crop is being taken before the plants are destroyed. In which case, the ban applies from 1st January until the final harvest is taken.

Includes ‘pasture legumes’ such as clover, lucerne, sainfoin and trefoil + other legumes such as beans, chickpeas, cowpeas, fenugreek, lentils, lupins, peas, soya and vetch.

All information is correct at the time of writing. Please check the latest details with your local advisor.
