Impacts of native forest in the recovery of soils degraded by salts in Lambayeque

Abstract

Con el propósito de conocer los impactos de la reforestación y recuperar suelos degradados por sales, se evaluó en la Comunidad Campesina San José, provincia y departamento de Lambayeque. cuatro especies forestales nativas: Prosopis limensis Benth (algarrobo), Acacia macracantha Humb. & Bonpl. ex Willd (faique), Caesalpinia spinosa (Molina) Kuntze (tara) y Schinus molle L (molle), especies evaluadas en tres niveles de salinidad. Se elaboraron formatos con matrices de evaluación de respuesta para evaluar las interrelaciones suelo-planta y otros componentes biológicos. Las especies seleccionadas mostraron buena adaptabilidad a suelos salinos, destacando el algarrobo y el faique; los resultados permiten concluir que las especies forestales trabajadas, tienen impacto beneficioso en la recuperación de suelos salinos, además otros beneficios y para la actividad pecuaria por el incremento de la biomasa formada que se puede aprovechar, captura de carbono y agua más del 30% del peso de la madera y a la nueva vida que alberga.

With the purpose of knowing the impacts of reforestation and recovering soils degraded by salts, it was evaluated in the lands of the San José Rural Community, province, and department of Lambayeque. four native forest species: Prosopis limensis Benth (carob), Acacia macracantha Humb. & Bonpl. ex Willd (faique), Caesalpinia spinosa (Molina) Kuntze (tara) and Schinus molle L (molle), species evaluated at three levels of salinity. Formats with response evaluation matrices were developed to evaluate the soil-plant interrelationships and other biological components. The selected species showed good adaptability to saline soils, highlighting the carob and faique. that they have the property of growing on abandoned lands that contain excess salts and having as a reference that in the past these species have existed in the area, but that they were cut down to build the keels of the boats; The evaluations show that the forestry species worked have a positive impact on the recovery of saline soils, in addition to other benefits and for the livestock activity due to the abundant biomass formed that can be used, carbon capture and water more than 30% of the weight of the wood and the new life it houses.
