Fluid Journal : Fall 2015
Using Fluid Fertilizer in Drip Irrigation Drs. Terry A. Tindall and Galen Mooso Timing of fertigation depends on crop. JOURNAL Official Journal of the Fluid Fertilizer Foundation Fluid Fall 2015 • Vol. 23, No. 4, Issue #90 ARTICLES THE FLUID JOURNAL - MISSION The Fluid Journal is published by the Fluid Fertilizer Foundation. The FFF is a non-profit organization committed to researching and providing information about fluid fertilizer technology. Since its formation, the FFF has funded over $3 million in fluid fertilizer research. We have 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 farmers and dealers so they may be better informed as to the technological advancements that the fluid fertilizer industry has achieved. FOCUS The Fluid Journal is focused on disseminating fluid fertilizer technology to universities, dealers, equipment manufacturers and fertilizer producers. Our editorial matter focuses on several areas: • Evaluate the agronomics of fluid fertilizers in the production of maximum economic crop yields • Evaluate application techniques for fluid fertilizers. • Investigate and inform our readers of innovative uses of fluid fertilizers under varied cultural, pest control and water management practices. • Evaluate the efficiencies and conveniences of fluid fertilizer systems. • Evaluate methods of controlling environmental problems with fluids.
