- Abstract: The use of reclaimed water to cope with water scarcity has become one of the main alternative resources in water‐deficit countries. Reclaimed water represents a significant component in integrated water resources management in the city of Madrid (Spain). Madrid City Council replaced the usual drinking water irrigation system by a reclaimed water one. This study assessed the effects of reclaimed water irrigation on micronutrient concentration (B, Cu, Fe, Mn and Zn) in the soil–plant system of two urban green areas in Madrid. Results showed that reclaimed water used in Madrid was adequate for irrigation regarding the studied micronutrients. Nevertheless, micronutrient concentration were slightly higher in reclaimed water than in drinking water. Soil organic matter (SOM) and pH had strong influence in some of the micronutrient concentrations in soils and in its bioavailability and transference to cedars (SOM ↔ B Soil, Cu Soil, Fe Soil ; pH ↔ B Soil, Fe Soil, Mn Soil ). There was no significant correlation between micronutrient concentration in irrigation water and in cedar leaves. Thus, foliar concentration of the studied micronutrients did not exceed toxic limits, even after 15 years of reclaimed water irrigation. Moreover, despite one park was irrigated with reclaimed water 10 years more than the other, reclaimed water irrigation plots did not show major differences in micronutrient concentration between the two parks.

Rėsumė: L'utilisation de l'eau recyclée pour faire face à la pénurie d'eau est devenue l'une des principales ressources alternatives dans les pays à déficit hydrique. L'eau recyclée représente une composante importante de la gestion intégrée des ressources en eau dans la ville de Madrid (Espagne). La mairie de Madrid a remplacé le système d'irrigation par eau potable habituel par un système à eau récupérée. Cette étude a évalué les effets de l'irrigation à l'eau de récupération sur la concentration en micronutriments (B, Cu, Fe, Mn et Zn) dans le système sol‐plante de deux espaces verts urbains de Madrid. Les résultats ont montré que l'eau recyclée utilisée à Madrid était adéquate pour l'irrigation en ce qui concerne les micronutriments étudiés. Néanmoins, la concentration en micronutriments était légèrement plus élevée dans l'eau de récupération que dans l'eau potable. La matière organique du sol (MOS) et le pH ont eu une forte influence sur certaines des concentrations de micronutriments dans les sols et sur sa biodisponibilité et son transfert aux cèdres (SOM ↔ B Sol, Cu Sol, Fe Sol; pH ↔ B Sol, Fe Sol, Mn Sol). Il n'y avait pas de corrélation significative entre la concentration de micronutriments dans l'eau d'irrigation et dans les feuilles de cèdre. Ainsi, la concentration foliaire des micronutriments étudiés n'a pas dépassé les limites toxiques, même après 15 ans d'irrigation à l'eau de récupération. De plus, bien qu'un parc ait été irrigué avec de l'eau recyclée 10 ans de plus que l'autre, les parcelles d'irrigation à l'eau recyclée n'ont pas montré de différences majeures de concentration en micronutriments entre les deux parcs. … (more)
