High ratio of synthesis (mole ratio of urea and formaldehyde is about 1:2), free formaldehyde content in more than five gung. Mainly through chemical synthesis slow soluble and difficult to soluble fertilizer, fertilizer, directly or indirectly to covalent or ionic bond to form polymer in advance, form a new type of polymer, such as urea formaldehyde resin coating slow-release fertilizer, its nutrient release has a dual effect of slow release and controlled release, urea formaldehyde resin coating slow release compound fertilizer field experiments showed that the use of a given amount of nutrient fertilizer, urea formaldehyde resin coating slow-release fertilizer can effectively improve the utilization rate of nitrogen, phosphorus and potassium, increase crop yield and quality
