An article I wrote with Dr. Frank Rossi about the Park Grass experiment at Rothamsted has recently been published in the USGA Green Section Record. One of these measurements is the botanical composition of the plots, and the results are amazing. This book explains the six principles of ideas that are remembered. For instance, fertilization of the Park Grass plots with g.m-2 of N. as ammonium sulfate, led to dominance by the grassAgrost~s (84% of community biomass compared with an average abundance in unfertilized control plots of 12%) and to the loss of 14 of the 19 plant species found, on average, in unfertilized control plots (44, 68~.
