The Agricultural Engineers Assiciation (AEA) is a trade association representing manufacturers and importers of agricultural machinery and outdoor equipment (horticulture, professional and leisure grass care, and forestry). The AEA was established in 1875 to promote the technical, trade and commercial interests of British manufacturers and suppliers of agricultural machinery. Since then it has championed the cause of manufacturers of agricultural machinery and more recently outdoor power equipment. Today its members cover a broad spectrum of manufacturers of land based equipment from combine harvesters to secateurs and everything in between. A subsidiary of the AEA is the National National Sprayer Testing Scheme (NSTS) who will also be present on the AEA's stand. This scheme has been part of UK agriculture since 2003 and is a main pillar of the Voluntary Initiative. NSTS tested sprayers are a requirement of the UK crop assurance scheme and supermarket protocols and NSTS satisfies the sprayer testing requirements of the Sustainable Use Directive.
