Dataset: Woburn long-term liming experiment crop yields 1962-1996

The experiment tests the effects of different amounts of lime (and thus soil pH), P and K on the yields of a sequence of arable crops, on a sandy loam 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. There was a parallel experiment at Rothamsted Experimental Farm. This experiment was discontinued in 1997. The dataset contains plot and sub-plot yields for all plots and years, 1962-1996, details of all treatments applied (lime, P, K, Mg, Mn and S) and agronomic details (crop variety, sowing and harvest dates, basal fertilizer).

This dataset was partially funded by the BBSRC Institute Strategic Programme Soil to Nutrition (BBS/E/C/000I0310).

本实验于1962年至1996年间在沃本试验农场（Woburn Experimental Farm）的砂壤土上开展，旨在探究不同石灰施用量（进而调控土壤pH值）、磷（P）与钾（K）对一系列耕地作物产量的影响。镁（Mg）、锰（Mn）及硫（S）的相关试验在不同时段于裂区设置中开展。实验预设的目标土壤pH值分别为4.5、5.5、6.5与7.5。同期在洛桑试验农场（Rothamsted Experimental Farm）开展了一项平行实验。本实验于1997年正式终止。本数据集涵盖1962年至1996年所有试验小区及裂区的产量数据、所有施加的田间处理措施（石灰、P、K、Mg、Mn及S）的详细信息，以及相关农艺参数（作物品种、播种与收获日期、基肥施用方案）。
