On the Integration of Sea Ice Information into ECDIS

A mineral composite consists essentially of a naturally occuring glacial deposit comprising not more than 20 weight percent Si-containing compounds, 10-20 weight percent Ca-containing compounds, 2-10 weight percent Mg-containing compounds, 2-10 weight percent Fe-containing compounds, 1-10 weight percent K-containing compounds, 1-5 weight percent Al-containing compounds, 0-3.0 weight percent Na-containing compounds, 0-5.0 weight percent Ti-containing compounds, 0-1.0 weight percent Mn-containing compounds, 0-0.5 weight percent P-containing compounds, 0-0.01 weight percent Ba-containing compounds and 0-0.005 Cr-containing compounds; and wherein the mineral composite is in powdered form with a mean particle size of 2-20mu and with a surface area of least of 0.8-1.5 m2/cm3 of the composite. Other additives may be added to the mineral composite to make it even more effective for treating soil. Methods of making and using the mineral composite are also described.
