Yes I agree. But does he use it over all his cereals? And if not, and it's so good, why not?Sorry for my slightly facetious response. Tim seems to be a brand ambassador for them - I can't blame them for wanting to surf the wave of success. Tim's YEN record attempts haven't always worked out well with a clear net margin over input costs. He withdrew his attempt in at least one year when the yield potential was limited for what may be other reasons. He was spending circa £150/ha extra on Bionature products, so needed the higher yield potential to show the net gain. That said, he seemed to be ahead most of the time.
