Impact of a long-term sugarcane harvesting system on crop performance, micronutrient availability, and soil organic carbon in tableland soils of Linhares-ES, Brazil
Unburned sugarcane harvesting has become a reality in Brazil, bringing impacts on sugarcane cultivation that are still not fully understood. This study evaluates the long-term impact (32 years) of different sugarcane harvesting systems—burned (B), unburned (U), and their alternation—on crop productivity, juice and stalk technological parameters, and soil micronutrient and organic carbon (OC) levels. The experiment, initiated in 1989, covered four cultivation cycles in Espírito Santo—Brazil. The experimental area comprised five blocks with four plots. Treatments included unburned harvesting, burned harvesting, and their alternations during the cycles. Evaluations were carried out in 2021, on the 5th ratoon of the fourth cycle. Productivity and technological quality of the juice and stalk were analyzed. Soil samples were collected at different depths and analyzed for OC content and the micronutrients B, Cu, Fe, Mn and Zn. Harvesting method combinations did not affect the productivity of dry leaves, tops, or stalks, nor the technological parameters. Average B and Fe contents were adequate, while Cu, Mn, and Zn were below recommended levels. The contents of Cu, Fe and Mn varied significantly between harvesting systems. While the harvesting systems over 32 years did not influence the productivity and technological parameters of the crop, the levels of micronutrient, except for B and Zn, and OC were affected by the different harvesting approaches. Although burned systems showed some positive responses, their continued use is not recommended due to environmental concerns. Sustainable alternatives should be prioritized to ensure long-term soil health and sugarcane viability.
期刊介绍:
The journal Sugar Tech is planned with every aim and objectives to provide a high-profile and updated research publications, comments and reviews on the most innovative, original and rigorous development in agriculture technologies for better crop improvement and production of sugar crops (sugarcane, sugar beet, sweet sorghum, Stevia, palm sugar, etc), sugar processing, bioethanol production, bioenergy, value addition and by-products. Inter-disciplinary studies of fundamental problems on the subjects are also given high priority. Thus, in addition to its full length and short papers on original research, the journal also covers regular feature articles, reviews, comments, scientific correspondence, etc.
