Diversidad microbiana en cultivos ecológicos: aproximación meta-analítica

Abstract

La diversidad microbiana de los suelos agrícolas se está viendo afectada debido a los manejos convencionales. Una alternativa para frenar la pérdida de diversidad son los manejos orgánicos/ecológicos. En este estudio he evaluado las ventajas de la adopción de este tipo de manejos para la conservación de la biodiversidad microbiana del suelo, considerando el posible efecto de la técnica de estudio y de la variabilidad entre tipos de cultivo. Para ello he realizado una búsqueda bibliográfica de artículos que hayan testado esta hipótesis con el objetivo de desarrollar un meta-análisis. Los resultados generales mostraron un efecto positivo en la diversidad microbiana bajo manejo orgánico. Estos resultados no variaron entre los tipos de cultivo evaluados. Además, encontré que el resultado general era aún más claro cuando se consideraban sólo trabajos que utilizaban técnicas de secuenciación más modernas. Pese a lo preliminar de este estudio, estos resultados claramente apoyan la adopción de manejos ecológicos.

Soil microbial diversity is negatively affected by conventional cropping systems. An environmental friendly alternative are organic cropping systems. In this study I have valuated the advantages to adopt such kind of cropping systems for the conservation of soil microbial diversity, considering the possible bias in results due to the crop type and the sequencing method use for such studies. For that, I have arranged a meta-analysis. The general result showed a positive effect of organic cropping modes on soil microbial diversity. This result did not vary between the crop types considered. By other hand, the general result was further confirmed when focusing the analysis on studies using massive sequencing approaches, but not on those with more classic microbiological methods. These results support the use of organic cropping systems.
