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]

open access: yes, 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

Earthworm populations in conventional/organic arable-based systems and their contribution to soil fertility OF0117T [PDF]

open access: yes, 1995
The project aimed to characterise earthworm population dynamics and behaviour under rotational cropping, comparing organic and conventional systems. Benefits arising from earthworm activity in terms of soil fertility were also assessed.

Profiling of the Microbiome Associated With Nitrogen Removal During Vermifiltration of Wastewater From a Commercial Dairy. [PDF]

open access: yes, 2018
Vermifiltration is a biological treatment process during which earthworms (e.g., Eisenia fetida) and microorganisms reduce the organic load of wastewater.

Anecic earthworms and associated ecosystem services in a ley-arable crop [PDF]

open access: yes, 2010
Een vruchtwisseling van gras en maïs zou duurzaam kunnen zijn in termen van nutriëntengebruik, maar het effect op regenwormen is nog onvoldoende bekend.

Roots and earthworms under grass, clover and a grass-clover mixture [PDF]

open access: yes, 2010
White clover has a lower root biomass and a higher abundance of earthworms than grass. This might have an impact on the ecosystem services soil structure maintenance and water regulation when white clover is introduced in a grass-clover mixture.
