AB  - This dataset contains annual spring barley yield data for all plots of the Exhaustion Land Experiment, 1949-1975, and agronomic details including sowing dates and varieties. No yields were recorded 1940-1948.  Basal nitrogen fertilizer was applied to all plots 1940-1974; no other fertilizer or manure was applied. This phase of the experiment tests the residual effects of different fertilizers and manures applied 1856-1901.
