PROCESSING METHOD

摘要

The inventors provide a method of processing biological material into a water- retaining polymer complex, a water- retaining polymer complex obtained from said method, and the use of said water- retaining polymer complex to improve the water retention and/or nutrient content of soil. The method comprises the steps of providing said biological material, an alkaline solution and a monomer, then adding a polymerisation agent to form a water- retaining polymer complex.
