Waste paper is shredded and reacted with nitric acid to produce nitrated cellulose in which the inorganic nitrate ion is organically bound to the cellulosic waste paper. The resultant product is neutralized to enhance its stability and is suitable for use as a nitrogen fertilizer and soil conditioner. When phosphoric acid is added prior to neutralization with potassium hydroxide a complete N-P-K fertilizer results.
