Through changing the level of each factor which influences the slow-release characteristics of silicon-potash fertilizer in "The technics of modifying desiliconized slags into slow-release silicon-potash fertilizer",the release rate of potassium in the modified silicon-potash fertilizer was determined in water and citric acid solution,respectively.

Silicon-potash fertilizer is a new kind of mineral potash fertilizer made of insoluble rock containing potassium,which is citrate soluble.

Modification of desiliconized slags into slow-release silicon-potash fertilizer is a typical complicated technology with multiple processes and factors.
