In a ®eld trial (1985±1996) on a sandy loam soil the effects of tractor traf®c and fertilisation on earthworm populations were investigated. The tractor traf®c treatments compared normal farm practice (`normal') with reduced tractor traf®c (`low'). In the fertilisation treatments, three different cattle-manure management methods were compared. The cattle manure was applied as diluted slurry, as...

19 The objective of this study was to relate earthworm assemblage structure with three 20 different soil use intensities, and to indentify the physical, chemical, and 21 microbiological variables that are associated to the observed differences in earthworm 22 assemblage structure between soils. Three soil uses were evaluated: 1Fifty year old 23 naturalized grasslands, low use intensity; 2Cattle...

In a former paper Kellogg and the writer have described the effects of a galvanic current on the body positions of Lumbricus Ierres~ris. 1 When the current flows transversely through such an animal or piece of one, the muscles respond by unilateral contraction on the cathodal side. The result is to bring the ends of the worm toward the cathode, thus forming a U with the median part nearest the ...

Bioinspired Robots In article number 2206336, Qinyan Zhou, Jian Xu, and Hongbin Fang pioneer a neurobiologically inspired control architecture for earthworm-like robotic in-pipe locomotion. The distributed oscillators serve as mapping between earthworm neural oscillations segment deformations, the collective dynamics of oscillator network is exploited to achieve complex gait patterns better loc...

Abstract Vermicompost is an organic fertilizer resulting from the decomposition of materials by utilizing earthworms. The presence these microorganisms means that vermicompost contains compounds are needed to increase soil fertility or for plant growth. This study aims analyze nutrients bio-vermicompost with a combination application techniques beneficial microbes and used factorial Completely ...

To meet the challenge of feeding a growing world population with minimal environmental impact, we need comprehensive and quantitative knowledge of ecological factors affecting crop production. Earthworms are among the most important soil dwelling invertebrates. Their activity affects both biotic and abiotic soil properties, in turn affecting plant growth. Yet, studies on the effect of earthworm...

For the last 150 years many studies have shown the importance of earthworms for plant growth, but the exact mechanisms involved in the process are still poorly understood. Many important functions required for plant growth can be performed by soil microbes in the rhizosphere. To investigate earthworm influence on the rhizosphere microbial community, we performed a macrocosm experiment with and ...
