From G. J. Badley
David Tilman finds that a plot sown with many types of grass produces more
hay than a plot sown with one
(3 November, p 16).
This is scarcely pioneering stuff, as it’s noted in chapter 4 of
On the Origin of Species(6th edition, p 137),
though I’m sure Darwin would approve of Tilman’s quantitative
precision.
Tilman is unsure how “the findings will scale up to real-world ecosystems”.
The eccentric “Squire of Down” had some thoughts on this too.
