Fertilidade do solo e desenvolvimento de trigo e soja em resposta adubação com pó de basalto

Abstract

In view of the large amount of basaltic residues coming from the processing of basalt, the possibility of basalt powder being a complement to mineral fertilization can be considered a sustainable and economically viable option. In view of this, the purpose of the present work was to evaluate the ability of basalt powder to be a supplement to the mineral fertilizer for the development of wheat and soybeans, as well as to increase soil fertility. The experiment was carried out at the federal Technological University of Paraná (UTFPR) Campus two neighbors, in the period from June 2016 to May 2018. The experimental area is at an altitude of 526 meters. The experimental design was of random blocks, consisting of four treatments with three repetitions, which are treatments with doses of basalt powder (0, 3, 6, 12 t/Ha-1) Consortium with soluble fertilizer in doses 250 kg/ha-1 In the formulation 16-16-16 for wheat and 450 kg/ha-1 In the formulation 04-28-08 for soy. The Plots will be 8m x 4m Totaling 32 m2. In 2016 the first application of the basalt powder was carried out, in 2017 the second application was carried out, with the doses being cultivated, the wheat of which the productivity was evaluated and the hectolitre weight (PH) was subsequently cultivated and the soy culture was evaluated and the Productivity variables and mass of a thousand grains (MMG). To evaluate the chemical attributes of the soil, three soil samplings were carried out (2016, 2017, 2018) at depths 0-5, 5-10, 10-15 cm, evaluating the contents of Al, PH, SB, V%, Ca, P and K. How much results were found only in the Productivity of soybeans and in the levels of K, for Variables No changes were found.
