Rothamsted Research, previously known as the Rothamsted Experimental Station and then the Institute of Arable Crops Research, is one of the oldest agricultural research institutions in the world, having been founded in 1843. It is located at Harpenden in the English county of Hertfordshire and is a registered charity under English law. One of the station's best known and longest-running experiments is the Park Grass Experiment, a biological study that started in 1856 and has been continuously monitored ever since. The Rothamsted Experimental Station was founded in 1843 by John Bennet Lawes, a noted Victorian era entrepreneur and scientist who had founded one of the first artificial fertilizer manufacturing factories in 1842, on his 16th-century estate, Rothamsted Manor, to investigate the impact of inorganic and organic fertilizers on crop yield. Lawes had Henry King conduct studies on the application of bone dust to turnip fields between 1836 and 1838. In 1840 he hired Dobson, a chemist. He had experiments conducted with bone ash treated with sulphuric acid and various other mixtures. It is thought that the experiments were at least to some extent influenced by Justus von Liebig who had attended a meeting of the British Association at Liverpool in 1837. Lawes took out patents on manure mixtures and began a factory to manufacture them in 1843, the same year that Joseph Henry Gilbert replaced Dobson who had moved to Australia. Gilbert had trained under Liebig and with Lawes support, he launched the first of a series of long-term field experiments, some of which still continue. Over 57 years, Lawes and Gilbert established the foundations of modern scientific agriculture and the principles of crop nutrition. In 1902 Daniel Hall moved from Wye College to become director, taking a lower salary to join an establishment lacking money, staff, and direction. Hall decided that Rothamsted needed to specialise and was eventually successful in obtaining state support for agricultural research. In 1912 E.
