The Ca, K and Na ions were concentrated due to the reduction of organic matter in the compost, while their concentration decreased in the vermicompost.

An alternative to reduce the environmental impact of manure is its treatment through composting. Rajkumar Rathinavelu y Giorgio Graziosi. Something went wrong, please try again. The germination index, using lettuce seeds Lactuca sativa L. So the decomposition of the food for the worm is more fast and is perform with greater efficiency is take in has the size of them pieces of it matter organic, besides the time in decomposition that this leads. Temperature is one of the most important factors governing the velocity of biochemical reactions in composting Defrieri et al.

The final mean of pH by composting presented a value of 8. K and Na concentrations were higher in the compost than in the vermicompost. These in order to drain fluids.

Fricke and Vogtmann reported an average Mg content in compost of 0. The containers with the substrate were protected from the environment with a plastic tunnel constructed with metal rods and semi-transparent plastic, with a maximum height of 40 cm. As well, Fricke and Vogtmann recommended a maximum content of mg kg -1 of Zn, and mg kg -1 of Cu over the dry weight in the compost to avoid problems of toxicity by these elements, which was achieved satisfactorily in both substrates. Statistical analysis A linear model was adjusted to analyze the data.

Prepare 4 containers with drain 3. Remember me on this computer. However, this application is generally not done appropriately, taking into account the soil characteristics and nutritional requirements of crops, which can result in damage to the health of the ecosystem, such as the salinization of soils, the lixiviation of nitrates to aquifers and the runoff of nitrates and phosphates to surface water bodies.


Given this, some characteristics of the soil should be taken into consideration, such as texture, organic matter content and the infiltration velocity, when determining the length of the storage period. Ready To Do More?

The model included as fixed effects, the effects of composting and vermicomposting systems; the effect of time over the weeks of observation; and the interaction among them. Consequently, the substrates produced in this study should be considered as semi-composted. There was a significant increase in K in the vermicompost, which could be because K is essential for worm growth. The mixture was removed each week from the containers for composting to increase aeration and reduce the formation of anaerobic zones.

This characteristic should be taken into consideration when the semi-composted product is applied to the soil as an improver.


The materials were previously stabilized and placed in 4 wooden boxes with 2 kg of soil, to which were added a population of 10 mature individuals measuring between 8 and 10 cm. Help Center Find new research papers in: Physiochemical analysis The temperature of the mixture was monitored for the 25 wk of maturation by inserting a thermometer to a depth of 20 cm at the center of each container every 48 h at It is the original image provided by the contributor.

Earthworms, transforming all the organic matter in their path, to transform the remains of coffee uses them to increase its population, directly affecting their reproductive cycle or the time in which performed it.

However, a higher pH was found in the compost, with a value of californiaan. Quality of source separated compost. A mixture was prepared using two types of organic residues, manure from valiforniana herd of dairy cows and pine sawdust. Save Try Share Edit. Liquid wastes generated in the production of earthworm flour were determined and evaluated under the following biological indicators: The waste characterization allowed determining that they are domestic water and process water.

A linear model was adjusted for the germination index, which included the composting method as a fixed effect.

Because there is no information about the nutritional requirements of the worm, it is difficult to assume that this decrease is due to feeding by the worms. As well, the compost presented higher levels of the alkaline cations K, Mg and Na, which can also have influenced its behavior. Four containers were used for the composting system and four for vermicomposting. 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.


Its absorption from the substrate promoted the expected increase by reducing dry matter from the substrate.

In vermicomposting, the pH of the medium plays a very important role in directly influencing worm alimentation and reproduction, preferring pH values close to 7. The process of vermicomposting lasted 45 days, until the end of the count. The substrate under the vermicomposting decomposition system in this study presented mean temperatures within the growth range established for worms for the major part of the process, and there were optimal temperatures beginning in week 13 of the study.

The mixture was agitated horizontally for 1 h and centrifuged at rpm for 15 min. The storage process generally tends to increase the stability of composting and vermicomposting products in a similar manner, which allows for removing the worms from the material in decomposition once it has reached maturity and integrate them in the decomposition of new organic matter, given that the humification process does not occur in the worm digestive system of the worm.

Consequently, this increase can be considered positive. Because it was observed during the experiment increased the size of the worms that were control in the Group and less cocones compared with the experimental proof.

The values correspond to the mean of six observations.
