Plant–soil feedback is a process where plants alter the biotic and abiotic qualities of soil they grow in, which then alters the ability of plants to grow in that soil in the future. Negative plant–soil feedback occurs when plants are less able to grow in soil that was previously occupied by a member of the same species, and positive plant–soil feedback occurs when plants are more able to grow in soil that was previously occupied by a member of the same species. Although it was originally assumed that negative plant–soil feedback was caused by plants depleting the soil of nutrients, recent work has suggested that a major cause of plant–soil feedback is a buildup of soil-borne pathogens. Mutualism and allelopathy are also thought to cause plant–soil feedback. Studies have shown that, on ave

| - La retroalimentación planta-suelo es el proceso en el que una especie de planta altera los factores bióticos y abióticos del suelo en el que crece, lo que altera la aptitud del suelo para el establecimiento futuro y potencial de la propia especie en relación con otras. Bajo esta premisa hay dos posibles escenarios. Una retroalimentación negativa entre planta y suelo se produce cuando especímenes de plantas son menos capaces de crecer en un suelo que anteriormente estaba ocupado por un miembro de la misma especie, mientras que una retroalimentación positiva se produce en el caso contrario, cuando las nuevas plantas tienen una mayor capacidad de crecer en un suelo anteriormente colonizado por sus pares conespecíficos. Así, un efecto positivo puede afectar la diversidad de un ecosistema, mientras que un efecto negativo puede ayudar a la coexistencia de una comunidad. El estudio de casos de retroalimentación planta-suelo tiene importantes aplicaciones en el entendimiento de las dinámicas de sucesiones ecológicas, así como en la adaptabilidad y el control de especies invasoras, en cuyos procesos este fenómeno puede otorgar perspectivas nuevas para su abordaje.

- Plant–soil feedback is a process where plants alter the biotic and abiotic qualities of soil they grow in, which then alters the ability of plants to grow in that soil in the future. Negative plant–soil feedback occurs when plants are less able to grow in soil that was previously occupied by a member of the same species, and positive plant–soil feedback occurs when plants are more able to grow in soil that was previously occupied by a member of the same species. Although it was originally assumed that negative plant–soil feedback was caused by plants depleting the soil of nutrients, recent work has suggested that a major cause of plant–soil feedback is a buildup of soil-borne pathogens. Mutualism and allelopathy are also thought to cause plant–soil feedback. Studies have shown that, on average, plant–soil feedback tends to be negative; however, there have been many notable exceptions, such as many invasive species. Negative plant–soil feedback is thought to be an important factor in helping plants to coexist. If a plant is over-abundant, then soil pathogens and other negative factors will become common, hurting its growth. Similarly, if a plant becomes overly rare, then so too will its soil pathogens and other negative factors, helping its growth. This negative feedback will help populations to stay in the community. Negative plant–soil feedback has been called a particular case of the Janzen–Connell hypothesis. (en)
