资源简介：
The data set contains yield data from a longterm field experiment. Thetreatments were tillage (ploughing/no-ploughing), mineral nitrogenfertiliser (70/120 kg N/ha a ) and organic fertiliser (100 t to 150t/ha acattle slurry). The crop rotation were sugar beet-springbarley-potato-winter wheat (1981-1990) and sugar beet-winter wheat-maize-triticale (1991-2001).
