• comprises less than 1% water which also provides improved stability of urease inhibitors.

A fertilizer additive that can evenly coat fertilizer granules and impart to the fertilizer the property of liberating bound nutrients when the coated fertilizer is applied to the soil wherein said fertilizer additive comprises one or more polyorganic acids and/or their salts in an organic liquid solvating system comprising one or more protic solvents or a mixture of aprotic and protic solvents,

• wherein the aprotic solvents are selected from the group consisting of a) dimethyl sulfoxide, b) one or more members selected from the group consisting of a dialkyl sulfoxide, diaryl sulfoxide, and an alkylaryl sulfoxide having the formula
