Organic nitrogen fertilisation of spring cereals

Summary

One problem in organic cereal production is poor grain quality resulting from low grain protein content. The objectives of these experiments were to improve grain yield and quality through application of organic N-fertiliser. The effects of green mulch fertilisation, and of both fertilisers applied simultaneously to spring wheat were studied. On spring barley, the effect of green mulch fertilisation, slurry fertilisation, and the possible effect of the previous year's treatment on spring wheat were of interest. The experiments were done at Kourla organic research farm of the Agric. Engineering Research Unit at Vihti in southern Finland.
