Resumen en español

Muchos estudios sugieren que las prácticas de manejo de la caña de azúcar tienen un impacto negativo en la calidad del suelo, especialmente en los organismos del suelo, sin embargo, la información sobre la abundancia y diversidad de macroinvertebrados en los campos de caña de azúcar convencionales es escasa. Este estudio determinó la abundancia y diversidad de macroinvertebrados del suelo en plantaciones de caña de azúcar en dos tipos de suelo, Cambisol y Fluvisol, tres tipos de manejo de fertilizantes: fertilizante químico, vinaza, cachaza, y en un bosque secundario (en un Cambisol). El muestreo fue llevado a cabo en el norte de Belice durante dos ciclos agrícolas (de mayo 2013 a mayo 2015). Los macroinvertebrados del suelo fueron colectados usando monolitos basados en el método del Manual de Métodos Tropical Soil Biology and Fertility (TSBF) al final de las temporadas de lluvia.

Los parámetros evaluados fueron biomasa, densidad y diversidad de macroinvertebrados del suelo (número de morfoespecies, un índice ecológico para la calidad del suelo tropical y un índice de Shannon convertido (H_exp)), rendimiento y variables de las plantas (número de cepas, número de tallos, número de hojas activas, largo del tallo y diámetro del tallo). Un total de 7,634 individuos fueron identificados, agrupados en 52 morfoespecies pertenecientes a 16 Ordenes y tres especies de anélidos. No existió diferencias significativas entre los sistemas de manejo (aplicación de fertilizante químico, vinaza, cachaza y bosque secundario) en la abundancia y diversidad de macroinvertebrados, rendimiento y variables de las plantas. Sin embargo, hubo diferencias significativas entre suelos y ciclos en algunos de los parámetros. Suponiendo que el tipo de suelo y las condiciones estacionales, en un ensayo de dos años, tuvieron mayor peso para determinar los parámetros estudiados que los diferentes sistemas de manejo.

Resumen en inglés

Many studies suggest that sugarcane management practices have negative impact on soil quality, especially on soil organisms, however, information on macroinvertebrate abundance and diversity in conventional sugarcane fields is scarce. This study determined the abundance and diversity of soil macroinvertebrates in sugarcane plantations under 2 types of soils, Cambisol and Fluvisol, with three types of fertilizer management: chemical fertilizer, vinasse and filter mud, and in a secondary forest (on a Cambisol). Sampling was carried out in northern Belize during two crop cycles (from May 2013 to May 2015). Soil macroinvertebrates were collected using monoliths based on Tropical Soil Biology and Fertility (TSBF) Handbook of Methods at the end of the rainy seasons. The parameters evaluated were biomass, density and diversity of soil macroinvertebrates (number of morphospecies, an ecological index for tropical soil quality based on macrofauna, and a converted Shannon index (H_exp)), yield and plant response variables (number of stool, number of stem, number of active leaves, stem length and stem diameter). A total of 7,634 individuals were identified, grouped into 52 morphospecies belonging to 16 orders and three species of annelids. No significant differences existed among management systems (application of chemical fertilizer, vinasse, filter mud and secondary forest) on abundance and diversity of soil macroinvertebrates, yield and plant variables. However, there were significant differences between soils and cycles in some evaluated parameters. Presuming that soil type and seasonal conditions, in a two years trial, had higher weight on determine the studied parameters than the different management systems.

Resumen en inglés

Plastic residues could accumulate in soils as a consequence of using plastic mulching, which results in a serious environmental concern for agroecosystems. As an alternative, biodegradable plastic films stand as promising products to minimize plastic debris accumulation and reduce soil pollution. However, the effects of residues from traditional and biodegradable plastic films on the soil-plant system are not well studied. In this study, we used a controlled pot experiment to investigate the effects of macro- and micro- sized residues of low-density polyethylene and biodegradable plastic mulch films on the rhizosphere bacterial communities, rhizosphere volatile profiles and soil chemical properties. Interestingly, we identified significant effects of biodegradable plastic residues on the rhizosphere bacterial communities and on the blend of volatiles emitted in the rhizosphere. For example, in treatments with biodegradable plastics, bacteria genera like Bacillus and Variovorax were present in higher relative abundances and volatile compounds like dodecanal were exclusively produced in treatment with biodegradable microplastics. Furthermore, significant differences in soil pH, electrical conductivity and C:N ratio were observed across treatments. Our study provides evidence for both biotic and abiotic impacts of plastic residues on the soil-plant system, suggesting the urgent need for more research examining their environmental impacts on agroecosystems.

Resumen en inglés

Microplastic pollution is becoming a major challenge with the growing use of plastic. In recent years, research about microplastic pollution in the environment has become a field of study with increased interest, with ever expanding findings on sources, sinks and pathways of microplastics. Wastewater treatment plants effectively remove microplastics from wastewater and concentrate them in sewage sludge which is often used to fertilise agricultural fields. Despite this, quantification of microplastic pollution in agricultural fields through the application of sewage sludge is largely unknown. In light of this issue, four wastewater treatment plants and 16 agricultural fields (0–8 sewage sludge applications of 20 e 22 tons ha-¹ per application), located in the east of Spain, were sampled. Microplastics were extracted using a floatation and filtration method, making a distinction between light density microplastics (ρ < 1 g cm−³) and heavy density microplastics (ρ > 1 g cm−³). Sewage sludge, on average, had alight density plastic load of 18,000 ± 15,940 microplastics kg-¹ and a heavy density plastic load of 32,070 ± 19,080 microplastics kg-¹. Soils without addition of sewage sludge had an average light density plastic load of 930 ± 740 microplastics kg-¹ and a heavy density plastic load of 1100 ± 570 microplastics kg-¹. Soils with addition of sewage sludge had an average light density plastic load of 2130 ± 950 microplastics kg-¹ and a heavy density plastic load of 3060 ± 1680 microplastics kg-¹. On average, soils’plastic loads increased by 280 light density microplastics kg-¹ and 430 heavy density microplastics kg-¹ with each successive application of sewage sludge, indicating that sewage sludge application results in accumulation of microplastics in agricultural soils.

Resumen en inglés

The accumulation of plastic debris and herbicide residues has become a huge challenge and poses many potential risks to environmental health and soil quality. In the present study, we investigated the transport of glyphosate and its main metabolite, aminomethylphosphonic acid (AMPA) via earthworms in the presence of different concentrations of light density polyethylene microplastics in the litter layer during a 14-day mesocosm experiment. The results showed earthworm gallery weight was negatively affected by the combination of glyphosate and microplastics. Glyphosate and AMPA concentrated in the first centimetre of the top soil layer and the downward transport of glyphosate and AMPA was only detected in the earthworm burrows, ranging from 0.04 to 4.25 μg g−¹ for glyphosate and from 0.01 (less than limit of detection) to 0.76 μg g−¹ for AMPA. The transport rate of glyphosate (including AMPA) from the litter layer into earthworm burrows ranged from 6.6 ± 4.6% to 18.3 ± 2.4%, depending on synergetic effects of microplastics and glyphosate application. The findings imply that earthworm activities strongly influence pollutant movement into the soil, which potentially affects soil ecosystems. Further studies focused on the fate of pollutants in the microenvironment of earthworm burrows are needed.

Resumen en español

Los extractos de composta y lombricomposta representan una alternativa al uso de fertilizantes y plaguicidas sintéticos, debido a sus efectos benéficos en plantas. El objetivo de este trabajo fue identificar la relación entre el efecto en la germinación de semillas de tomate y las características microbiológicas y fisicoquímicas de extractos obtenidos por distintos métodos. Los factores evaluados fueron: el método de extracción (aireado / no aireado), proporción (composta:agua) y proceso de transformación de los residuos (composta / lombricomposta). La materia prima empleada fue una mezcla de fibra de palma africana, pulpa de café y residuos orgánicos de mercado. Se encontró relación entre la diversidad microbiana y el índice de germinación, así como una dependencia del contenido de nutrientes con el método de extracción empleado. Mediante el análisis discriminante canónico identificamos que los factores que optimizaron el efecto de los extractos en el índice de germinación de semillas, y su relación entre ellos, fueron: los obtenidos de composta, la proporción 1:3 (composta:agua) y el método no aireado

Resumen en inglés

Microplastics are emerging as a steadily increasing environmental threat. Wastewater treatment plants efficiently remove microplastics from sewage, trapping the particles in the sludge and preventing their entrance into aquatic environments. Treatment plants are essentially taking the microplastics out of the waste water and concentrating themin the sludge, however. It has become common practice to use this sludge on agricultural soils as a fertilizer. The aimof the current researchwas to evaluate the microplastic contamination of soils by this practice, assessing the implications of successive sludge applications by looking at the total count of microplastic particles in soil samples. Thirty-one agricultural fields with different sludge application records and similar edaphoclimatic conditions were evaluated. Field records of sludge application covered a ten year period. For all fields, historical disposal events used the same amount of sludge (40 ton ha−¹ dry weight). Extraction of microplasticswas done by flotation and particles were then counted and classifiedwith the help of a microscope. Seven sludge samples were collected in the fields that underwent sludge applications during the study period. Soils where 1, 2, 3, 4, and 5 applications of sludge had been performed had a median of 1.1, 1.6, 1.7, 2.3, and 3.5 particles g−¹ dry soil, respectively. There were statistical differences in the microplastic contents related to the number of applications that a field had undergone (1, 2, 3 b 4, 5). Microplastic content in sludge ranged from 18 to 41 particles g−¹, with a median of 34 particles g−¹.

The majority of the observed microplastics were fibers (90% in sludge, and 97% in soil). Our results indicate that microplastic counts increase over time where successive sludge applications are performed. Microplastics observed in soil samples stress the relevance of sludge as a driver of soil microplastic contamination.

Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, and biomass. We found that local species richness and abundance typically peaked at higher latitudes, displaying patterns opposite to those observed in aboveground organisms. However, high species dissimilarity across tropical locations may cause diversity across the entirety of the tropics to be higher than elsewhere. Climate variables were found to be more important in shaping earthworm communities than soil properties or habitat cover. These findings suggest that climate change may have serious implications for earthworm communities and for the functions they provide.

Resumen en inglés

In the current study, we examine how the activities of earthworms (Lumbricus terrestris) affect microplastic (MP) distribution and concentration in soil, with a focus on low density polyethylene (LDPE). We also want to determine if MPs can be flushed out with water. We used a laboratory sandy soil column (polyvinyl chloride tube) experimental set-up and tested five different treatments: (1) treatment with just soil (control) to check if the saturated conductivity (Ksat) could be impacted by MP, (2) treatment with MP, (3) treatment with MP and litter, (4) treatment with earthworms and litter as a second control for treatment 5 and (5) treatment with MPs, earthworms and litter. Each treatment consisted of eight replicates. For the treatments with MP, the concentration of MP added at the start of the experiment was 7 % by weight (3.97 g, polyethylene, 50 % 1 mm–250 µm, 30 % 250 µm–150 µm and 20 % <150 µm) based on 52.78 g of dry litter from Populus nigra. In the treatments using earthworms, two adult earthworms, with an initial average weight of (7.14 ± 0.26) g, were placed in each column. Results showed that LDPE particles could be introduced into the soil by the earthworms.

MP particles were detected in each soil sample and within different soil layers for the earthworm treatments. Earthworms showed a tendency to transport the smaller MP particles and that the amount of MPs in size class <250 μm increased in soil samples with increasing soil depth in comparison to the other size classes. After leaching, MPs were only detected in the leachate from the treatments with the earthworms, and the MP had similar size distributions as the soil samples in the 40–50 cm layer of the treatment with MP, earthworms and litter. The results of this study clearly show that biogenic activities can mobilise MP transport from the surface into the soil and even be leached into drainage. It is highly likely that biogenic activities constitute a potential pathway for MPs to be transported into soil and groundwater.
