La eficiencia de los inoculantes en plantas se ve afectada por la secreción de compuestos de las raíces en respuesta a diferentes condiciones ambientales, que interfieren en la interacción planta-bacteria. La salud del suelo, incluyendo tipo de suelo, nutrientes, metales tóxicos, humedad, diversidad microbiana y prácticas de manejo, también influye. Los mecanismos de promoción del crecimiento vegetal por bacterias varían según la especie y cepa, sin un mecanismo único. Estudios en bacterias endófitas (que colonizan tejidos vegetales internos sin causar daño) muestran promoción del crecimiento vegetal en diversas etapas del ciclo de vida de la planta, mediante diferentes mecanismos.

Plant roots react to different environmental conditions through the secretion of a wide
range of compounds which interfere with the plant-bacteria interaction, being considered
an important factor in the efficiency of the inoculants.
Soil health is another important factor that affects the inoculation efficiency, due to
several characteristics such as soil type, nutrient pool and toxic metal concentrations, soil
moisture, microbial diversity, and soil disturbances caused by management practices.
Mechanisms of Plant Growth Promotion
The mechanisms by which bacteria can influence plant growth differ among
species and strains, so typically there is no single mechanism for promoting plant growth.
Studies have been conducted regarding the abilities of various bacteria to promote plant
growth, among them the endophytic bacteria. Endophytes are conventionally defined as
bacteria or fungi that colonize internal plant tissues, can be isolated from the plant after
surface disinfection and cause no negative effects on plant growth. Many bacteria promote
plant growth at various stages of the host plant life cycle through different mechanisms
