Fluid Journal : Early Spring 2011
13 The Fluid Journal Early Spring 2011 Foundation, located in Manhattan, Kansas. Annually, it gathers its dealer members, researchers, suppliers, and manufacturers--domestically and overseas--to assemble at its Fluid Forum in Scottsdale, Arizona, to learn about Figure 2.

Tri decades The first near tri decade (1953 - 1980) of innovation and development led to the second near tri decade (1980 -- 2011) of fine tuning fertilizer application rates for NPK, new concepts for weed and feed, free lunch meetings for growers to learn about the latest chemicals on the market, the introduction of precision agriculture: variable rate application, G.P.S. systems, yield monitors, bio tech, and new higher- yield hybrids.Dramatic jump The jump in corn yield over a period just short of sixty years (see Figure 1) is nothing less than dramatic and fluids have played a significant role in this increase. Back in the fifties, 40 bu/A of corn was considered the norm. Since then the adrenaline is readily apparent. From the '70s to the year 2,000, corn yields jumped at the rate of 1.9 bu/A each year. Over the next nine years it jumped at the rate of 3 bu/A each year. The goal by 2030? Estimates range from 250 to 300 bu/A per year or
