The influence of humic acids derived from earthworm-processed organic wastes on plant growth.
The incorporation of both types of vermicompost-derived humic acids, into either type of soilless plant growth media, increased the growth of tomato and cucumber plants significantly, in terms of plant heights, leaf areas, shoot and root dry weights.
Pig manure vermicompost as a component of a horticultural bedding plant medium: effects on physicochemical properties and plant growth.
This experiment was designed to characterize the physical, chemical and microbial properties of a standard commercial horticultural, greenhouse container, bedding plant medium that had been substituted with a range of increasing concentrations of pig manure vermicompost and to relate these properties to plant growth responses.
Influence of earthworm-processed pig manure on the growth and yield of greenhouse tomatoes
The eAects of earthworm-processed pig manure (vermicompost) on germination, growth, and yields of tomato (Lycopersicon esculentum Mill.) plants were evaluated under glasshouse conditions and some of the growth and yield enhancement resulting from substitution of Metro-Mix 360 with pig manure verMicompost could be attributed to the high mineral N concentration of the pig manure.
Effects of vermicomposts and composts on plant growth in horticultural container media and soil
Summary Vermicomposts, which are produced by the fragmentation of organic wastes by earthworms, have a fine particulate structure and contain nutrients in forms that are readily available for plant
Changes in biochemical properties of cow manure during processing by earthworms (Eisenia andrei, Bouché) and the effects on seedling growth
Summary The biochemical changes in fresh cow manure caused by the earthworm Eisenia andrei (Bouche) were measured over a period of four months, under controlled laboratory conditions. Earthworms were
The influence of earthworm-processed pig manure on the growth and productivity of marigolds.
Substitution of Metro-Mix 360 with any concentration of pig manure vermicompost, with all needed nutrients provided, increased the overall nitrate-nitrogen concentrations of the marigold leaf tissues at flowering stage and may be explained by nutritional factors.
Effects of vermicomposts produced from food waste on the growth and yields of greenhouse peppers.
Factors such as: an improvement of the physical structure of the potting medium, increases in populations of beneficial microorganisms and the potential availability of plant growth-influencing-substances produced by microorganisms in vermicomposts could have contributed to the increased pepper yields obtained.
Earthworm-Processed Organic Wastes as Components Of Horticultural Potting Media for Growing Marigold and Vegetable Seedlings
We germinated and grew tomato, pepper, lettuce, and marigold seedlings in a standard commercial soilless plant growth medium (Metro-Mix 360), and in coir/perlite and peat/perlite-based container
Vermicompost stimulates mycorrhizal colonization of roots of Sorghum bicolor at the expense of plant growth
Steam sterilization of vermicompost had no consistent effect on mycorrhizal colonization but generally enhanced dry weights relative to the non-sterile treatment, and inoculation with AMF reduced dry weights particularly at the higher rate (20%) of verMicompost.
Effects of humic acids derived from cattle, food and paper-waste vermicomposts on growth of greenhouse plantsThe 7th international symposium on earthworm ecology · Cardiff · Wales · 2002
Summary Humic acids were extracted from cattle, food and paper-waste vermicomposts using an alkali/acid fractionation procedure which produced 1 g dry wt humates from 400 g vermicompost. They were
