Redução do volume de irrigação de plantio de eucalipto para ganhos operacionais, sociais e ambientais

Abstract

The forestry Market has expanded throughout the world significantly in recente years. Because of this growth, the challenges of increasing productivity and competitiveness among companies for forestry training based on sustainable ESG (Enviroental, Social and Governance) concepts growth as well. Therefore, this Project aims to assess the potential for reducing the volume of irrigation water from Eucalyptus forestry activities. The Project analyzed the operations of irrigated planting and conventional planting (planting and irrigation independent) and was divided into five main treatments: T0 (no irrigation), T1 (an irrigation of 250 ml/plant), T2 (an irrigation of 4 l/ plant), T3 (two irrigations, the first being 250 ml/plant) and T4 (two irrigations of 4 l/plant). The experiments were executed in São Paulo state between may to december and genetical material does not present any resistance to water deficit. The initial results measured the mortality rate of the different treatments and presented no significant results between T3 and T4 from may to june and significant results between T3 and T4 from july to august. There is a potential to reduce the volume of water during planting to 250 ml/plant in the first irrigation during humid period of the year. As a result, opportunities to reduce the volume of irrigation water were identified, with significant gains in the use of renewable resources and in line with ESG guidelines.
