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).
