Rothamsted Research

where knowledge grows

With remarkable prescience, Lawes and Gilbert retained samples of crops, soils, fertilisers and manures applied to the experiments. Successive generations of scientists at Rothamsted have continued to add to the collection and the resulting Sample Archive now comprises > 300,000 samples. This unique resource is of immense value. New analyses of archived material continue to provide insights into changes occurring over 170 years. No other long-term experiments have such an archive.
