PURPOSE:To provide an aerosol mousse fertilizer whose applied amount can be readily known by eye measure, by charging an aqueous solution containing fertilizer components and a specific surfactant together with a propellant into a pressure vessel under pressure. CONSTITUTION:An aqueous solution is prepared by using fertilizer components such as dipotassium phosphate, 0.01-2wt.% of nonionic surfactant such as poly-oxyethylene lauryl ether or a combination thereof with less than 30wt.%, based on the total surfactants, of cationic, anionic and amphoteric surfactants. The aqueous solution is pressure-charged together with a propellant such as dimethyl ether into an aerosol vessel to give the subject aerosol mousse fertilizer. The fertilizer forms fine foam and can be applied in a fluidal emulsion form. Thus, the amount of the fertilizer applied can be known easily by eye measure.
