| description | Prosopis alba is the most important native species in the semi-arid Chaco for afforestation with multiple objectives. More than 50% of the planted area in Santiago del Estero, Argentina, has been established in areas with very different site quality, generating a heterogeneous growth behavior. It is proposed to evaluate the influence of edaphic factors on the growth of plantations Prosopis alba Griseb (algarrobo) in areas of the semi-arid Chaco, information that will facilitate silvicultural decision making and will allow predicting the quality of sites with forestation potential based on conditions of the soil. The correlation between dasometric and edaphic variables was evaluated in relation to 3 kinds of site quality (CI, CII and CIII). A dominant height projection model expressed as a Site Index with the most correlated edaphic variables was determined, which explains 42% of the variation in growth. The electrical conductivity has a threshold of 10 dS m-1 for the CI and CII with Site Index of 10 and 8 respectively; for higher EC values the growth of the mass decreases. The concentration of soluble cations varies in relation to the site index, the CI and CII have low sodium concentrations, with a critical value of approximately 39 mEq L-1. Growth is conditioned by chemical properties of the soil, the presence of salts would further explain the impact on growth, with a saline threshold from which growth is compromised from a productive approach. |

Prosopis alba Griseb es la especie nativa de mayor importancia en el Chaco semiárido para la forestación con múltiples objetivos. Más de 50% de la superficie plantada en la provincia de Santiago del Estero, Argentina, se ha establecido en áreas con calidades de sitio muy diferentes, generando un comportamiento heterogéneo en el crecimiento. Se propone evaluar la influencia de factores edáficos en el crecimiento de plantaciones de Prosopis alba Griseb (algarrobo blanco), información que facilitará la toma de decisiones silviculturales y permitirá predecir la calidad de sitio con potencial de forestación, con base en características edáficas. Se evalúo la correlación entre variables dasométricas y edáficas en relación con tres clases de calidad de sitio (CI, CII y CIII). Se determinó un modelo de proyección de altura dominante, expresado como índice de sitio con las variables edáficas de mayor correlación, que explica 42% de la variación en el crecimiento. La conductividad eléctrica presentó un umbral de 10 dS m-1 para la CI y CII con índice de sitio de 10 y 8 respectivamente; para valores superiores de CE disminuyó el crecimiento de la masa. La concentración de cationes solubles varió con respecto al índice de sitio, la CI y CII presentaron concentraciones bajas de sodio, con un valor crítico de aproximadamente 39 mEq L-1. El crecimiento estuvo condicionado por propiedades químicas del suelo, la presencia de sales explicaría en mayor medida el impacto en el crecimiento, con un umbral salino a partir del cual el crecimiento se ve comprometido desde un enfoque productivo.
