This dataset was done gathering and calculating data from an experiment integrated in the Circular Agronomics project. In October 2019 an experiment was setup in a randomized block design where 5 different irrigated winter crops were grown in 2 3-year rotations by 3 seasons. Several crop and and soil variables were measured to test for responses under different fertiliser treatments, including untreated and dried acidified digestates. There were also different crop precedents especifically for wheat, since this was the common crop between both rotations (cereal and diverse). With the gathered data we were able to calculate and test for differences in grain yield and N concentration, N uptake efficiency and water use efficiency of the different crops under different fertilisation and rotation (wheat) treatments. Also the soil was tested for differences in soil nitrates at 3 time points during the 3 seasons and soil total nitrogen at the end of the experiment.
