N supply in stockless organic cereal production under northern temperate conditions. Undersown legumes, or whole-season green manure? [PDF]
, 2007 Two systems for nitrogen (N) supply to organic spring cereals were compared under Norwegian conditions. Repeated undersowing of clover in the cereals in four growing seasons was compared to a whole-season green manure in the second year.

Forage yields from ryegrass and ryegrass-cereal grain mixtures
California Agriculture, 1978 During two years of study no increase in pasture production could be obtained by adding barley to ryegrass. Instead, ryegrass yield was depressed the remainder of the growing season. Overall, ryegrass planted alone equalled or was better than the mixtures.

The role of earthworms in nitrogen release from herbage residues : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Soil Science at Massey University [PDF]
, 1987 Decomposition and nutrient release from pasture litter were examined in two biotic systems; either with or without large organisms ("macrobes"). Earthworms were the test macrobe and nitrogen (N) the test nutrient. This experiment addressed the hypothesis
