Atributos químicos do solo e produção da cana-de-açúcar em resposta ao silicato de cálcio

Abstract

The use of calcium silicate in Brazilian agriculture is restricted, although it is an economically viable target for the use of part of these by-products of steel industry in recent decades, has been accumulating with the growth of Brazilian steel park. The objective of this study was to evaluate the effect of doses of calcium silicate in the chemical soil properties and production of cane sugar. The work was conducted in the field, adopting the experimental design of randomized blocks with four replicates, the treatments consisted of different doses of calcium silicate (0, 700, 1400, 2800, 5600 kg ha-1). The study was conducted in the field, adopting the experimental design of randomized blocks with four replicates, the treatments consisted of different doses of calcium silicate (0, 700, 1400, 2800, 5600 kg ha-1). The calcium silicate added to the soil favored the increase in pH, Ca, Mg, Fe, Mn, SB, CTC and V% of the soil and decreases the levels of (H + Al), MO, Zn, Cu and Si. The application of calcium silicate provided significant increases in production of cane sugar.
