Relationships between soil chemical parameters and functional plant groups in fertility islands of the Arid Chaco (Argentina)

The “fertility islands” are the result of soil particles, water, nutrients, and biomass accumulation under their canopy. The study of soil and plant parameters in fertility islands is important for the redefinition of management strategies. The hypothesis is that Neltuma flexuosa and Larreadivaricat...

The study of soil and plant parameters in fertility islands is important for the redefinition of management strategies. The hypothesis is that Neltuma flexuosa and Larreadivaricata fertility islands in the Arid Chaco improve soil chemical properties under their canopies affecting the quality and quantity of forage. The objective is to evaluate soil chemical properties on the response of plants in fertility islands. The effect of nurse plants over soil chemical properties and their relation with functional plant groups was studied. Livestock carrying capacity (LCC) significantly increased under the canopy of N. flexuosa. Decreasers were positively related to the N. flexuosa canopy, and negatively to L. divaricata canopy. Soil organic carbon (OC) related positively with decreasers in N. flexuosa islands, but negatively in L. divaricata islands where there seems to exist allelopathy effect. Extractable phosphorus correlated positively with decreasers. Las “islas de fertilidad” son el resultado de la acumulación de partículas de suelo, agua, nutrientes y biomasa bajo su canopia. El estudio de parámetros de suelo y de vegetación en islas de fertilidad es importante para la redefinición de estrategias de manejo. La hipótesis es que las islas de fertilidad de Neltuma AGRISCIENTIAflexuosa y Larrea divaricata en el Chaco Árido mejoran las propiedades químicas del suelo bajo su canopia afectando la calidad y cantidad de forraje. El objetivo es evaluar las propiedades químicas del suelo sobre la respuesta de las plantas en islas de fertilidad. Se estudió la influencia de plantas nodrizas sobre propiedades químicas del suelo y su relación con grupos funcionales de plantas. La capacidad de carga ganadera (LCC) se incrementó significativamente bajo la canopia de N. flexuosa. Las especies decrecientes se relacionaron positivamente bajo canopia de N. flexuosa, y negativamente bajo L. divaricata. El carbono orgánico del suelo (OC) se relacionó positivamente con las especies decrecientes en islas de N. flexuosa, pero negativamente en las islas de L. divaricata donde aparentemente ocurre alelopatía. El fósforo extractable se correlacionó positivamente con las especies decrecientes.
