Title A name given to the resource Effect of Compost Application on Some Properties of a Volcanic Soil from Central South Chile Efecto de la Aplicación de Compost sobre Algunas Propiedades de un Suelo Volcánico de La Región Centro-Sur de Chile Creator An entity primarily responsible for making the resource Pedro José Valarini, Gustavo Curaqueo, Alex Seguel, Karina Manzano, Rosa Rubio, Pablo Cornejo, Fernando Borie Description An account of the resource Soil compost application is a common soil management practice used by small farmers of Central-South Chile that produces positive effects on soil properties and also promotes presence and activity of arbuscular mycorrhizal fungi (AMF). This fungi form symbiosis with plant roots improving plant nutrition, as well as producing glomalin, a glycoprotein that has been associated with soil aggregation stability. Therefore, the aim of this study was to evaluate, in an Ultisol from Central-South Chile, the effect of different doses of compost on some soil characteristics at the end of the third year of a crop sequence including wheat (Triticum aestivum L.), bean (Phaseolus vulgaris L.), and grassland (Lolium multiflorum Lam. associated with Trifolium repens L.). Studied soil characteristics included chemical (pH, available-P, organic C), biological (C and N biomass, AMF spore number, root colonization percentage, mycelium length, and glomalin content), as well as physical parameters (water holding capacity [WHC], and water stable aggregates [WSA]). Results showed that, in general, compost application increased soil pH, mycorrizal roots, mycelium length, glomalin levels, and WSA. Significant relationships were found between C and N biomass, C biomass and WSA, C biomass and glomalin, WSA and WHC, among others. Results suggest that compost application to this type of soil is a feasible option as a fertilizer substitute, and a way to avoid soil erosion by small local farmers involved in organic agriculture.La aplicación de compost al suelo, práctica habitual en predios de pequeños agricultores de la región centro-sur de Chile, produce efectos positivos en sus propiedades y promueve la presencia y actividad de los hongos micorrícicos arbusculares (AMF). Estos hongos forman simbiosis con las raíces de las plantas mejorando su nutrición y además producen una glicoproteína llamada glomalina, la cual ha sido relacionada con la estabilidad de los agregados de suelo. Por lo anterior, el objetivo de este estudio fue evaluar el efecto de la aplicación de distintas dosis de compost sobre algunos parámetros de un Ultisol de la zona centro-sur de Chile, al finalizar el tercer año de una secuencia de cultivos formada por trigo (Triticum aestivum L.), frejol (Phaseolus vulgaris L.) y pradera permanente (Lolium multiflorum Lam. asociada con Trifolium repens L.). Se estudiaron parámetros químicos (pH, C orgánico, P-Olsen), biológicos (C y N biomásico, número de esporas de AMF, micorrización de raíces, longitud de micelio y niveles de glomalina), y físicos (capacidad de retención de agua, WHC, y agregados estables al agua, WSA). Los resultados mostraron que, en general, la aplicación de compost incrementó el pH, micorrización radical, niveles de glomalina, longitud del micelio fúngico y porcentaje de WSA. Se encontraron correlaciones entre C y N biomásico, C biomásico y WSA, C biomásico y glomalina, WSA y WHC. Los resultados aportan antecedentes sobre el uso beneficioso de compost como una alternativa viable de sustitución de insumos y disminución de la erosión en asentamientos de pequeños agricultores orientados a la agricultura orgánica.
