The aim of the project is to find an optimal level of nitrogen fertilisation for whole crop harvests of pea/oat mixtures.

An optimal level means a good yield with high crude protein content in combaination with low nitrogen leakage. The experiment has 7 different treatments, 3 with cattle manure and 3 with mineral fertiliser, with corresponding nitrogen levels, and 1 control with no added nitrogen. 

A. Control 20 kg P, 50 kg K

B. 13 ton cattle slurry

C. 23 ton cattle slurry

D. 33 ton cattle slurry

E. 25 kg N, 20 kg P, 50 kg K

F. 45 kg N, 20 kg P, 50 kg K

G. 65 kg N, 20 kg P, 50 kg K
