Soil indicator data from a Conservation Agriculture trial in Eastern Cape, South Africa

The data was generated from the analysis of the soil samples that were collected from the conservation agriculture (CA) trial in Phandulwazi, Eastern Cape, South Africa. The experimental design for the treatments used was a split-split plot design. Standard soil extraction and analytical methods were used to generate the data. The tillage treatments were the conventional tillage (CT) and no-till (NT) and the residue management treatments were designated as follows: R+ as crop residue retention and R- as crop residue removal. The crop rotation treatments were maize-fallow-maize (MFM), maize-fallow-soybean (MFS), maize-wheat-maize (MWM) and maize-wheat-soybean (MWS).本数据集源自对南非东开普省潘杜瓦齐（Phandulwazi）保护性农业（conservation agriculture, CA）试验采集的土壤样品的分析。试验处理采用裂裂区试验设计。数据通过标准土壤提取与分析方法生成。耕作处理分为常规耕作（conventional tillage, CT）与免耕（no-till, NT）两类；秸秆管理处理设置如下：R+代表作物秸秆还田，R-代表作物秸秆移除。轮作处理包含玉米-休耕-玉米（MFM）、玉米-休耕-大豆（MFS）、玉米-小麦-玉米（MWM）以及玉米-小麦-大豆（MWS）四种模式。
