CHEMICAL AND MICROBIOLOGICAL PROPERTIES OF GOAT MANURE DURING COMPOSTING AND VERMICOMPOSTING.
Goat manure is produced in large quantities and for either their storage or dispersion in soils, or both, this residue can cause atmospheric and water pollution. Therefore, it is necessary to stabilize it for agronomic usage. Vermicompost presents chemical and microbiological characteristics that make it biologically more stable and therefore suitable for its use as an organic fertilizer. The objective in this study was to compare the changes in the chemical and microbiological properties of goat manure during composting and vermicomposting, for biological stabilization. For it, manure was collected at pens from the goat module of the UAEM University Center, Temascaltepec Farm, Mexico. The manure was then composted for 45 d in 300 kg conical piles. Vermicomposting with Eisenia fetida lasted 60 d. At the end of the processes, samples were taken for chemical and microbiological analysis. The substrates were monitored for their temperature and 80 % humidity was maintained. The experimental design was completely randomized, with two treatments (T1: goat manure compost, T2: vermicompost goat manure) with six repetitions each. The data was analyzed via one-way ANOVA, and the microbiological variables were analyzed with descriptive statistics. The variables pH, organic matter (OM), organic carbon (OC) and total nitrogen (TN) between the processes showed differences (p?0.001, p?0.0001, p?0.0001, p?0.007, respectively). The electric conductivity (EC) and the C : N relation between the evaluated processes were different (p?0.0001, p?0.031, respectively). The Ca, Mg, P and Na content decreased in the vermicompost (p?0.0001). A higher content of Pseudomonas, fungi (Aspergillus) and actinomycetes was detected in the vermicompost. Thus, the biological stabilization of goat manure by composting is different from vermicomposting in their chemical variables and microbial content.

| description |
Goat manure is produced in large quantities and for either their storage or dispersion in soils, or both, this residue can cause atmospheric and water pollution.
Therefore, it is necessary to stabilize it for agronomic usage. Vermicompost presents chemical and microbiological characteristics that make it biologically more stable and therefore suitable
for its use as an organic fertilizer. The objective in this study was to compare the changes in the chemical and microbiological properties of goat manure during composting and
vermicomposting, for biological stabilization. For it, manure was collected at pens from the goat module of the UAEM University Center, Temascaltepec Farm, Mexico. The manure was then
composted for 45 d in 300 kg conical piles. Vermicomposting with Eisenia fetida lasted 60 d. At the end of the processes, samples were taken for chemical and microbiological analysis. The
substrates were monitored for their temperature and 80 % humidity was maintained. The experimental design was completely randomized, with two treatments (T1: goat manure compost, T2:
vermicompost goat manure) with six repetitions each. The data was analyzed via one-way ANOVA, and the microbiological variables were analyzed with descriptive statistics. The variables pH,
organic matter (OM), organic carbon (OC) and total nitrogen (TN) between the processes showed differences (p?0.001, p?0.0001, p?0.0001, p?0.007, respectively). The electric conductivity (EC)
and the C : N relation between the evaluated processes were different (p?0.0001, p?0.031, respectively). The Ca, Mg, P and Na content decreased in the vermicompost (p?0.0001). A higher
content of Pseudomonas, fungi (Aspergillus) and actinomycetes was detected in the vermicompost. Thus, the biological stabilization of goat manure by composting is different from
vermicomposting in their chemical variables and microbial content. |

The experimental design was completely randomized, with two treatments (T1: goat manure compost, T2: vermicompost goat manure) with six repetitions each. The data was analyzed via one-way ANOVA, and the microbiological variables were analyzed with descriptive statistics. The variables pH, organic matter (OM), organic carbon (OC) and total nitrogen (TN) between the processes showed differences (p?0.001, p?0.0001, p?0.0001, p?0.007, respectively). The electric conductivity (EC) and the C : N relation between the evaluated processes were different (p?0.0001, p?0.031, respectively). The Ca, Mg, P and Na content decreased in the vermicompost (p?0.0001). A higher content of Pseudomonas, fungi (Aspergillus) and actinomycetes was detected in the vermicompost. Thus, the biological stabilization of goat manure by composting is different from vermicomposting in their chemical variables and microbial content. El estiércol caprino se produce en grandes cantidades y su almacenamiento o la dispersión, o ambos, de este residuo en el suelo pueden causar contaminación de la atmósfera y el agua, por lo que es necesario someterlo a procesos de estabilización para su uso agronómico. El vermicompost presenta características químicas y microbiológicas que lo hacen biológicamente más estable y, por lo tanto, adecuado para su uso como fertilizante orgánico. El objetivo de este estudio fue comparar los cambios en las propiedades químicas y microbiológicas del estiércol de caprino durante el compostaje y vermicompostaje, para la estabilización biológica. El estiércol se recolectó en los corrales del módulo de caprinos del Rancho del Centro Universitario UAEM Temascaltepec, México. El estiércol se composteo por 45 d en pilas cónicas de 300 kg. El vermicompostaje con Eisenia fetida duró 60 d. Al final de los procesos se tomaron muestras para su análisis químico y microbiológico. En los sustratos se monitoreó la temperatura y se mantuvieron con 80 % de humedad. El diseño experimental fue completamente al azar, con dos tratamientos (T1: compost estiércol caprino, T2: vermicompost estiércol caprino) con seis repeticiones cada uno. Con los datos se realizó ANDEVA de una vía y las variables microbiológicas se analizaron con estadística descriptiva. Las variables pH, materia orgánica (MO), carbono orgánico (CO) y nitrógeno total (NT) entre los procesos, presentaron diferencias (p?0.001, p?0.0001, p?0.0001, p?0.007, respectivamente). La conductividad eléctrica (CE) y la relación C:N entre los procesos fueron diferentes (p?0.0001, p?0.031) respectivamente. El contenido de Ca, Mg, P y Na disminuyó en el vermicompost (p?0.0001). En el vermicompost se detectó un contenido mayor de Pseudomonas, hongos (Aspergillus) y actinomicetes. Así, la estabilización biológica de estiércol caprino por compostaje es diferente al vermicompostaje en variables químicas y contenido microbiano.
