An agricultural fertigation method includes the in situ manufacture of one or more fertilizers within the irrigation upstream of the agricultural field being irrigated. Co-reactant raw materials, namely sulfuric acid, phosphoric acid, nitric acid, potassium hydroxide, urea, ammonium hydroxide, ammonia, calcium nitrate and/or magnesium nitrate, are intermixed with each other and with the stream of the flowing irrigation water. The stream of flowing irrigation water dampens the resultant dissolution and reaction exotherms. A system wherein raw materials are efficiently fed to the irrigation system main line or a side-arm reactor efficiently implements the method.
