David Fulwood Nuffield Scholar. I know why they call these a Mother Bin. 85 tonnes of lupins as a standing hopper, just over 3 metres so could easily work in the UK. David showed me his photos of his time on his Nuffield travels. He recently took a global focus group to East Europe and it was good to see some familiar faces. David was gettig stuck into lupin harvest. Controlled traffic farming and over laying 10 years of maps to determine the good and bad parts of the fields. Where to invest and where not to farm. Making GPS technology work for you.
