%X dregs is an alkaline solid by-product generated in the cellulose manufacturing industry that could be used to correct soil acidity. the present study aimed to evaluate the chemical composition of this product and some of its properties. the dregs presented 354 g kg-1 of calcium, neutralization capacity of 80.3%, and ph 10.7, besides low concentration of sodium (10.2 g kg-1), lead (62.9 mg kg-1) and cadmium (5.6 mg kg-1). thus, it is a product that can safely be used to increase the soil ph.
