Aqueous urea solutions particularly suited for foliar fertilization are disclosed. They are characterized by low phytotoxicity, low corrosivity, and improved toxicity stability and comprise urea nitrogen and between about 0.005 and about 0.1 molar equivalents per mole of urea of a pH buffer having a buffering point between about 6 and about 7.6. Also provided are aqueous urea solutions suitable for foliar application containing mineral or organic acids, or both, in the presence or absence of a pH buffer having pH values between about 6 and 7.6. Either solution is foliarly applied at substantially non-toxic rates of at least about 10 pounds of nitrogen per acre.
