abstract = {To improve the utilization of fertilizer and water resource
at the same time, a new type of slow-release fertilizer with
superabsorbent and moisture preservation was developed, with
the combination of slow-release technique and superabsorbent
polymers. The coatings were formed by the inverse phase
polymerization technique. The element analysis results
showed that the product contained $22.58\%$ nitrogen
element, and the water absorbency of the product was 94
times its own weight if it was allowed to swell in tap water
at room temperature for 2 h. The results of the slow-release
behavior of N and the water absorbency and retention
properties in soil showed that the product not only had good
slow-release property but also had excellent water
absorbency and water retention capacity, which was a
significant advantage over the normal slow-release or
controlled-release fertilizers. The effects of the amount of
initiator, crosslinker, reaction time, and the degree of
neutralization of acrylic acid on water absorbency were
investigated and optimized. At the same, a rather new and
simple method was used to make homogeneous urea-formaldehyde
granules. (c) 2006 Wiley Periodicals, Inc.},
