Woburn long-term liming experiment soil chemical properties 1962-1996

The experiment tests the effects of different amounts of lime (and thus soil pH), P and K on a sequence of arable crops, on a sandy soil at Woburn Experimental Farm, from 1962-1996. Mg, Mn and S were tested on split plots at different times. Target soil pH was 4.5, 5.5, 6.5 and 7.5. This dataset contains soil pH, Olsen P and exchangeable cations (Ca, K, Mg and Na, ammonium acetate method) on soil sampled several times between 1962 and 1996. There was also a baseline sampling before the experiment was established. There is a parallel experiment at Rothamsted Experimental Farm. This experiment was discontinued in 1997.
