COBO VIDAL, Yakelin et al. Edaphic factors that involved in the availability of microelements in Vertisols planted with sugarcane. Rev Cie Téc Agr [online]. 2024, vol.33, n.2  Epub 01-Jun-2024. ISSN 2071-0054.

The objective of this study was evaluate the influence of the limiting factors of production: effective depth, slope, erosion, texture, drainage and salinity on the availability of Mn, Fe, Co, Ni, Cu and Zn in Vertisols planted with sugarcane from the Region of Cuba. A total of 262 soil samples were obtained by stratified random sampling. The available forms of microelements were determined with the diethylenetriaminepentacetic acid solution by the atomic absorption method. To explain the relationship between both sets of variables was used the Canonical Correlation Analysis. The results showed a strong correlation between the limiting factors drainage, salinity, slope, effective depth and texture and the availability of Co, Ni and Zn. It recommended appropriate agronomic practices that improve physical fertility and that favor the displacement towards the available forms of the microelements in Vertisols.
