Fertilidade do solo e desenvolvimento de feijão comum em resposta adubação com pó de basalto

Abstract

This study aimed to evaluate the performance of bean crop and changes in soil chemical properties by application of powdered basalt. The experiment was carried in Urupema (SC) in a completely randomized design, with the following treatments: control, conventional fertilization, basalt powder at rates of 2.5, 5, 10 and 20 t ha-1, cattle manure and the same doses of powdered basalt associated with cattle manure. Differences between treatments for soil pH, exchangeable Al, organic matter, P, Ca, Mg and Si were not found. The value of K was higher in soil treated with soluble fertilizer in relation to the control treatment. No differences were observed among treatments for yield and plant height, and the contents of N, P, K, Ca, Mg, Si, Cu, Zn, Fe, Mn were not affected by the application of basalt powder in two crops.
