AB  - This dataset contains annual spring barley yield data for all plots of the Exhaustion Land Experiment, 1976-1985, grain and straw uptake of P and K, and agronomic details. The plots were divided into four sub-plots testing four rates of nitrogen (N) fertilizer. No other fertilizers or manures were applied. This phase of the experiment tests the residual effects of different fertilizers and manures applied 1856-1901, in the presence of different rates of fertilizer N.
