“…Simmons et al . () found that SBS with compost and wheat bran enriched soil with taxa known to include micro‐organisms capable of degrading lignocellulosic material, such as members of the phylum Firmicutes, of the families Ruminococcaceae and Lachnospiraceae and of the genus Geobacillus (Simmons et al . ).…”

“…There have been reports describing the evolution of the microbial community relevant to lignocellulose bioconversion during soil solarization and SBS. Simmons et al (2016) found that SBS with compost and wheat bran enriched soil with taxa known to include micro-organisms capable of degrading lignocellulosic material, such as members of the phylum Firmicutes, of the families Ruminococcaceae and Lachnospiraceae and of the genus Geobacillus . However, the microbiome necessary for organic matter decomposition during SBS and the evolution of the SBS microbiome during treatment have not been fully investigated and might be expected to vary with amendment and soil type.…”

Aims Soil biosolarization (SBS) is a pest control technology that includes the incorporation of organic matter into soil prior to solarization. The objective of this study was to measure the impact of the initial soil microbiome on the temporal evolution of genes encoding lignocellulose‐degrading enzymes during SBS. Methods and Results Soil biosolarization field experiments were completed using green waste (GW) as a soil amendment and in the presence and absence of compost activating inoculum. Samples were collected over time and at two different soil depths for measurement of the microbial community and the predicted lignocellulosic‐degrading microbiome. Compost inoculum had a significant positive effect on several predicted genes encoding enzymes involved in cellulose, hemicellulose and lignin degradation. These included beta‐glucosidase, endo‐1,3(4)‐beta‐glucanase, alpha‐galactosidase and laccase. Conclusion Amendment of micro‐organisms found in compost to soil prior to SBS enhanced the degradation potential of cellulose, hemicellulose and lignin found in GW. Significance and Impact of the Study The type of organic matter amended and its biotransformation by soil micro‐organisms impact the efficacy of SBS. The results suggest that co‐amending highly recalcitrant biomass with micro‐organisms found in compost improves biomass conversion during SBS.

“…Al incorporar productos orgánicos con elevada presencia de N, como la cama de pollo (estiércol de gallina + cáscara de arroz) y gallinaza (estiércol de gallina puro), se produce inicialmente un descenso del pH (del Pino et al, 2007;Oka, 2010), ocasionado por la liberación de H + durante el proceso de nitrificación (Mengel and Kirkby, 2000), que se intensifica en suelos alcalinos (Oka, 2010). Sin embargo, de acuerdo al tipo de material que se incorpora el pH también puede aumentar por la presencia de cationes básicos que se liberan durante su descomposición (Dikinya and Mufwantala, 2010;Simmons et al, 2016). Es muy importante que el suelo tenga un pH que permita el desarrollo óptimo de los cultivos; para el tomate el rango se encuentra entre 5,5-6,5 (Nuez et al, 2003), valores por encima de este nivel afectan la disponibilidad de ciertos nutrientes y en consecuencia el rendimiento del cultivo (Porta et al, 2003).…”

En la región del Gran La Plata se produce bajo cubierta alrededor de 4.600 ha de cultivos agrícolas, sobre suelos Typic Hapludert y Vertic Argiudol, caracterizados por un drenaje deficiente, que junto a la calidad del agua de riego y al manejo intensivo, conducen a degradaciones físicas, químicas y biológicas, que se vinculan con una elevada carga de patógenos (enfermedades y nematodos). Por lo tanto, uno de los desafíos más importantes es encontrar alternativas de desinfección de suelo que se adapten al sistema productivo, que no contaminen ni degraden los recursos, y que promuevan una mejora de los suelos. En el presente trabajo se evaluó el efecto de diferentes tratamientos de desinfección en las propiedades edáficas (pH, CE, MO, RAS, Ca, Mg) y en el rendimiento de un cultivo. Los tratamientos evaluados fueron: solarización, biosolarización con cama de pollo (50 t ha-1), biosolarización con cama de champiñón (100 t ha-1), biosolarización con repollo (80 t ha-1), desinfección química y un testigo, en dos temporadas (2014 y 2015) de un cultivo de tomate. Se observó que la biosolarización con cama de pollo y de champiñón aumentó los niveles de salinidad y las concentraciones de Ca 2+ y Mg 2+ , sin una mejora significativa en los niveles de MO. La biosolarización con repollo no incidió en las variables del suelo. Los tratamientos de solarización y desinfección química se comportaron en forma similar al testigo. Respecto al rendimiento del cultivo la desinfección química presentó los mayores valores. El resto de los tratamientos no se diferenciaron significativamente (P < 0,05) entre sí. Palabras clave: solarización, biosolarización, tomate, cama de pollo, cama de champiñón, repollo, salinización, enmienda orgánica, producción bajo cubierta.
