UK raspberry production was worth £109M in 2014, but a further 11KT of berries, worth £59M, areimported each year. A 20% increase in the 14KT of fruit produced p.a. in the UK could be expected toreduce imports by 2.8KT, and raise the value of the UK industry by £15.7M p.a.. However, improved on-farm management of water and fertiliser inputs is needed to optimise productivity; currently, excessivefertigation to substrate-grown raspberry result in vigorous cane growth which makes crop managementdifficult and harvesting costly. Nutrient leaching also poses a risk to groundwater quality. We will usenovel affinity sensors combined with fuzzy logic to automatically adjust nutrient inputs to match plantdemand in real time, reduce fertiliser losses to the environment and improve berry quality. Stresspreconditioning and arbuscular mycorrhizal fungi (AMF) will be used to raise marketable yields, improveresource use and acquisition, and increase crop resilience to stresses.
