EVALUATION OF DIFFERENT TECHNOLOGIES FOR THE COMPACTION MANAGEMENT IN VERTISOIL
Main Article Content
Abstract
In sugarcane crop, soil compaction is a difficult problem to correct due to its high cost. This occurs due to the traffic of harvesting equipment, which prioritizes the operational efficiency of machines and implements, leaving soil as a last resort, resulting in decreased yields. The study aimed to evaluate the effect of three compaction management technologies on sugarcane agricultural yield. Six harvests from three experiments were analyzed on soils in the Vertisuelos agricultural cluster, under dryland conditions and during the second and third-shoot cycles harvested in two categories of soil moisture at harvest time. Agricultural yield and economic impact were assessed. Data were statistically processed using analysis of variance at a 0.05 error probability level using the Statgraphics v. 6.0 statistical package and the Duncan test at an equal level of significance to separate the means when significant differences were present. It was concluded that coverage of agricultural crop residues and decompaction, as technologies for managing compaction in Vertisoils, applied according to the methodology employed in the study, increase agricultural yield and profits.
