Spatial variability of soil attributes and sugarcane yield in relation to topographic location

Abstract: Soils submitted to the same management system in places with little variation of landscape, manifest differentiated spatial variability of their attributes and crop yield. The aim of this work was to investigate the correlation between spatial variability of the soil attributes and sugarcane yield as a result of soil topography. To achieve this objective, a test area of 42 ha located at the São João Sugar Mill, in Araras, in the State of São Paulo, Brazil, was selected. Sugarcane yield was measured with a yiel… Show more

“…A elevada correlação positiva entre SB e V (0,801) (Tabela 2) pode ser explicada, uma vez que o valor V é expresso pela relação entre SB e CTC T . Da mesma forma observou-se correlação positiva entre teor de MO e CTC T , corroborando com o estudo realizado por Souza et al (2010) em área cultivada com cana-de-açúcar. Isso se deve, principalmente, pela MO ser o principal contribuinte para o aumento da CTC T , sobretudo, em solos altamente intemperizados como os Latossolo.…”
