Woodland Restoration on Landfill Sites: Earthworm Activity and Ecosystem Service Provision
… may also assist the establishment of sustainable earthworm populations, which in turn can further aid soil development through their burrowing and feeding activities. Despite these potentially mutual benefits, little research exists into CGW and earthworm interactions with trees on reclaimed land, …

The effect of the lime-molybdenum interaction on some properties of pasture soils
… show the differences, if any, in soil structure, earthworm populations, organic matter content, mineralisation of soil nitrogen, exchangeable manganese content, and phosphate fixing power of the soil due to treatment in the field with lime and with molybdenum.

Earthworms in the Urban Environment: Can Population Augmentation Improve Urban Soil Properties?
… is often degraded by human activity. Because earthworms play a key role in soil health, augmenting earthworm populations in urban soils may improve tree performance. However, we know very little about earthworm ecology in highly urbanized soils. The objectives of our study were: (1) to assess …

To Mix or Not to Mix: Performance and Management of Diverse Cover Crop Mixtures
… pH, electrical conductivity, soil respiration, earthworm counts, soil microbial respiration, and soil microbial biomass carbon (C) after three years of CC. Cover crop biomass production varied significantly each year (5633 kg ha-1 in year 1, 755 kg ha-1 in year 2, 5370 kg ha-1 in year 3) due to …

An evaluation of soil and water management practices on a lowland soil with poor natural drainage
… indices of compaction and structural stability. Earthworm numbers and biomasses were measured in both farm. Land drainage through a system of subsurface drainlines was found to lower the water table more rapidly after rainfall, and reducing the depth and duration of ponding compared to undrained …

Earthworm dynamics in tallgrass prairies in the Ozark Highlands region of northwest Arkansas
… tallgrass prairies. Limited research exists on earthworm dynamics in mounded tallgrass prairies or prairie restorations, particularly in the Ozark Highlands region of northwest Arkansas. The objectives of this study were to i) evaluate the effects of soil moisture regime (SMR; aquic and udic), …

Ecosystem goods and services in semi-arid lanscape : an examination of the relationship between ecological processes, land-use strategies and biodiversity conservation
… However, under managed transformed conditions earthworm populations were three times greater than in natural vegetation remnants and this may account for greater infiltration rates measured here. An exploration of the potential to develop horticultural products from the species in the area, …
