Broadbalk experiment

Broadbalk experiment is one of the oldest and longest agronomic experiment in the world. Initiated in 1843 in Hertfordshire county of southern England, it sought to understand the effects of combinations of inorganic fertilizers and organic manures. Under this experiment, winter wheat is sown annually on a field named Broadbalk to compare crop yields grown using different fertilizers and manures. The experiment found that the cultivation after a two-year break results in higher yields and a reduction in soil-borne diseases and pests.
