Fluid Journal : Winter 2013
12 The Fluid Journal Winter 2013 Dr. Easterwood is Manager, Agronomic Services at Yara North America Inc. in Tampa, Florida. A special thanks to my colleague Dr. Joachim Lammel for supplying information for this article and editorial suggestions by Ned van Buren. China has become acutely aware of water scarcity. The Yellow River is the second longest river in China and is the cradle of their civilization and agriculture. Since 602 B.C ., Chinese historians have kept records of the Yellow River course changes and floods. But during 15 days in 1972, for the first time in their recorded history, the last 100 km of the river went dry. Nor was that the end of it. In 1997, the last 100 km were dry for 226 days. As a result, Chinese agricultural scientists are now seeing the value of drip fertigation compared to flood irrigation in terms of yield and water savings. For certain, inefficient water use will become a distant memory as water scarcity increases. Summing up Liquid fertilizers will play a crucial and leading role in generating product portfolios for fertigation to grow crops in an environment of dwindling water supplies. The bottom line is that the variables of population growth and water availability will drive our innovative efforts to conserve water and nutrients, yet maximize food production. 4 R’s also must be followed: • Right source • Right rate • Right timing • Right placement. The urgency. Time will tell, but we must be prepared to meet these agricultural challenges as our Founding Fathers did in such a masterful manner. The Fluid Journal, flagship publication of the Fluid Fertilizer Foundation (FFF), makes nearly two decades of archives available on its web site. The magazine investigates and informs its readers on innovative uses of fluid fertilizers under varied cultural, pest control, and water management practices, focusing on evaluating: the agronomics of fluid fertilizer in the production of maximum economic crop yields application techniques for fluid fertilizers the efficiencies and conveniences of fluid fertilizer systems methods of controlling environmental problems with fluids. Going on Twenty Years of Archives! Since its formation, the FFF has funded over $3 million in fluid fertilizer research and accumulated thousands of pages of research data. The main goal of the Fluid Journal is to transfer this technical information into easy-to-read form to its farmers and dealers. The Fluid Journal also provides links to its articles on Twitter: http://www.twitter.com/fluidjournal For information on how to become a member of the FFF, contact the foundation’s office at 785/776-0273 or the foundation’s website: http://www.fluidfertilizer.com
