The principles of Integrated Farm Management (IFM) underpin the requirements of LEAF Marque certification, as set out in the LEAF Marque Standard. IFM is a whole farm business approach that delivers more sustainable farming. Modern technology and traditional methods are used with the goal of delivering a prosperous farming that enriches the environment and engages local communities. A farm business managed to IFM principles will demonstrate site-specific and continuous improvement across the whole farm including: Organisation and Planning, Soil Management and Fertility, Crop Health and Protection, Pollution Control and By-Product Management, Animal Husbandry, Energy Efficiency, Water Management, Landscape and Nature Conservation and Community Engagement.
