Agricultural Limestone in Montérégie and Estrie

Manufacturing of Calcium, Magnesium and Dolomitic Lime

CACHO, our agricultural limestone, is BNQ certified and is recognized as one of the best products of its kind in Quebec. We have been producing it since 1949, proudly contributing to better agricultural yields for farmers. Soil fertilization is undoubtedly one of the biggest factors impacting crop yields. Our varieties of calcium, magnesium or dolomitic limestone make it possible to obtain a quality of soil more favourable to cultivation.
