TLDR
Analysis of soil earthworm populations in southwestern Ontario estimated mean earthworm density and biomass as 111 m −2 and 35 g m-2, respectively, for five cultivated sites concluded that the current gull flocks poses no danger to earthworms populations in cultivated southern Ontario soils.About:

Tillage and soil ecology: Partners for sustainable agriculture
TL;DR: In this article, the authors examine the impact of tillage on various groups of soil biota, outlining, through examples, the crucial effects of soil organisms and functions on population dynamics and species diversity, and tackle the question of the design of the tillage systems to enhance biological control in cultivated fields.

Changes in pore structure in a no-till chronosequence of silt loam soils, southern Ontario
TL;DR: In this article, short-term changes in soil micromorphology attributed to conversion to no-till from conventionally tilled management are evaluated and shown that the number of 30-to 100-µm diameter pore sizes decreased after 4 years of no-to-no till management.

Earthworm populations (Lumbricidae) in ploughed and undisturbed leys
TL;DR: The extent of earthworm injury caused by rotary cultivation followed by ploughing of a meadow fescue and a lucerne ley was estimated and earthworm biomasses in the ploughed leys and the undisturbed leys were estimated.

Estimating Earthworm Populations by Using Formalin
TL;DR: The permanganate method used by Evans and Guild has been shown by Svendsen2 greatly to under-estimate the population of L. terrestris and my tests at Wisbech confirmed this.
