Resumen

LUIZ-PARTELLI, Fábio; RAMOS-EVANGELISTA, Cristiano; CAYO-CAVALCANTI, André  y  GONTIJO, Ivoney. Properties of the fertility of a cane soil under different types of organic and conventional management. cultrop [online]. 2018, vol.39, n.4, pp.13-20. ISSN 0258-5936.

The sugarcane is one of the main crops produced in Brazil and is cultivated since the colonial Brazil Times. Soil management in the culture of sugarcane has undergone changes over time, applying new techniques of management and conservation of soil, taking advantage of systematic way the waste from the manufacture of alcohol and sugar, minimizing damage to environment. This aimed to evaluate the chemical attributes of the soil cultivated with sugarcane certified organic with and without soil disturbance, organic certification, conventional with and without straw burning and a remaining area of Cerrado in Goiatuba, Goiás, Brazil. Soil samples were collected in September 2009 in the depths of 0-10 cm and 10-20 cm for chemical analysis. The results were analyzed descriptively by estimating the mean, standard error of the mean and also by means of multivariate analysis, estimating the Euclidean average distance between the treatments with complete connection. There forming groups among the organic cultivation without soil disturbance and the remaining area of Cerrado in the depth 0-10 cm indicating proximity between the evaluated attributes. The organic cultivation without soil disturbance presents phosphorus and potassium far superior to other managements. The results underscore the importance of greater supply of organic waste for improved chemical attributes and maintenance of soil quality
