The germination index, using lettuce seeds Lactuca sativa L. Nevertheless, for Hansen et al. To leave her outside decaying, certain microorganisms such as fungi and bacteria help break down and give nutrients available to the worm to be converted into “humus” as a metabolic process.

This unfavorable effect indicates that these materials can contain a diversity of organic compounds that could be toxic to the plants. This work is related to a previous work made in the Technical University of Manabi, forprotein supplements production from unconventional raw materials, specifically Earthworm Eisenia foetida flour, using various ecotoxicological methods to evaluategeneratedwaste in pilot production, in order to contribute to compliance the environmental regulations.

ANOVA test one value less than 0. Leave in rest during days in a container closed with a small breather before introducing them to the system.

The concentrations of Ca, Mg and Na increased in both substrates after storage, which is expected given the decrease in dry matter. Add two systems remains of organic coffee 2. This problem indicates that manure is an important reservoir caiforniana contaminants that can potentially affect humans, or from another perspective, a novel potential industry with important applications.

Four containers were used for the composting system and four for vermicomposting. Log In Sign Up. P content decreased in both systems of composting during the storage period, which is contrary to what is expected given that P is not lost through volatilization or pombriz.

Only Fe concentration decreased sharply during storage, probably owing to the precipitation of this element, which is highly soluble in water. Toward the end of the experimental period, a P concentration of 0.

The necessity for have efficient tools in the environmental assessment of production processesis treated in this paper. The materials were previously stabilized and placed in 4 wooden boxes with 2 kg of soil, to which were added a population califorrniana 10 mature individuals measuring between 8 and 10 cm.

Ciencia Ergo Sum 8: Fricke and Vogtmann reported a maximum Roma content in compost of mg kg -1to avoid problems of toxicity by this heavy metal Table 1. Liquid wastes generated in the production of earthworm flour were determined and evaluated under the following biological indicators: Given this, the reduction of pH during the storage of vermicompost and compost to levels of 6.

However, in comparison to traditional calidorniana, vermicomposting requires a higher initial investment of capital and a higher technical capacity to ensure the viability of the annelids. Subsequently, the products were stored for 29 wk d in polyethylene bags at ambient temperature.

In this experiment, P concentration increased relatively, in both systems beginning in week 10, which could be the result of the decreased quantity of dry matter while the net quantity of this element should remain the same as the initial quantity. Standard methods for the examination of water and wastewater. This variation was reduced in the following sampling 4 wk after, when the concentrations of organic C tended to equalize Remember caliofrniana on this computer.


Both cases presented lower concentrations than those reported for compost and vermicompost by some authors Ducasal,a condition that can be considered desirable given that Na is reported as a cation that can increase the salinity of the soil and can affect the growth and development of plants sensitive to this element Castellanos et al.

At the end of the experimental period a concentration of 0. Equally, the low temperatures, the decrease in pH and the moisture of the residues favored the increase in total N content, which corresponds to the conditions observed in the vermicomposting system. Germination index of lettuce in vitro with extracts of vermicompost and compost at 21 and 25 weeks of decomposition. Save Try Share Edit. This characteristic lombrzi be taken into consideration when the semi-composted product is applied to the soil as an improver.

The values correspond to the mean of six observations. Something went wrong, please try again. Applied and Environmental Microbiology You can redownload your image for free at any time, in any size.
