The data set contains yield data from a longterm field experiment. The treatments were tillage (ploughing/no-ploughing), mineral nitrogen fertiliser (70/120 kg N/ha a ) and organic fertiliser (100 t to 150t/ha a cattle slurry). The crop rotation were sugar beet-spring barley-potato-winter wheat (1981-1990) and sugar beet-winter wheat- maize-triticale (1991-2001).
Methods (Experiment Design):
Crop rotation
1981-1990 sugar beet - spring barley - ( catch crop spring rye ) - potato - winter wheat (catch crop spring rye)
1991-2001 sugar beet - winter wheat (catch crop Sinapis arvensis) - silage maize - triticale (catch crop Phacelia)
Design
3 factor, 3 replications, every crop growing in each year (fields nr. 6 - 9)
factor a (soil cultivation)
treatment 1: plough 0,2 - 0,35 m, sugar beet and potato: plough in autumn before catch crop and spring
treatment 2: plough before sugar beet, potato and silage maize, conservation tillage with disc harrow and cultivator to winter wheat, spring barley and triticale
treatment 3: plough before sugar beet and potato, conservation tillage 0,1-0,2 m with power harrow and cultivator to winter wheat, spring barley, triticale and silage maize

The nitrogen fertilisation to winter wheat and spring barley was splitted in 3 or 2 parts
factor c (organic fertilization)
| year | 1981 -1991 | ||
| treatment 1 | 3,5 t FM/ ha catttle slurry to sugar beet and potato | ||
| treatment 2 | 4,5 t FM/ ha catttle slurry to sugar beet and potato | ||
| year | 1992 -2001 | ||
| treatment 1 | 20 t FM/ ha cattle manure to sugar beet and triticale straw after triticale harvest | ||
| treatment 2 | 40 t FM/ ha cattle manure to sugar beet and triticale straw after triticale harvest | ||
