Research was carried out to evaluate the chemical characteristics of Quartzarenic Neosol cultivated with olive tree ( Olea europaea L.) using organomineral fertilization and reduced amounts of chemical fertilization. Three-year-old olive trees of the variety ‘Grappolo 541’ were planted with a spacing of three meters between plants and five meters between rows in the area studied. The four treatments were 100%, 75%, 50% and 0% of the mineral fertilizer recommended for olive tree in a randomized block design with five replications and three plants per plot. The split-plot scheme was used, with four fertilization treatments in plot and sub-plot evaluation times. The organomineral fertilizer was applied to all plants in November 2011 and October 2012. Soil samples were taken before fertilization (November 2011) and after fertilization (July 2012 and June 2013). The data were subjected to an analysis of variance and regression with p |
