Fluid Journal : Winter 2015
3 The Fluid Journal Winter 2015 From The Publishers The four articles in this issue of the Fluid Journal deal with varying crops, nutrient concentrations, and placement methods to achieve high yields with fluid fertilizers. They represent on- going research promoted by the Fluid Fertilizer Foundation (FFF) to achieve and promote the well-advised goal of using our resources to achieve ever higher crop yields to feed an ever- growing world population. It furnishes our dealers, their grower customers, our member companies, and the vast worldwide audience we reach on our website with information they can use in the battle against world hunger. In the leading article on improving alfalfa yields--using NPK fluid fertilizers- -the responses were impressive, bringing 2:1 economic returns. Yield improvements, with 6-24-6, provided over a 3-ton (@65% moisture) improvement over the grower standard practice of 20.5 tons, compared to 23.3 . The 2014 study by J. R. Simplot, a current FFF member, continued via ongoing applications and measurements to build a better understanding of how to The Fluid Journal • Official Journal of the Fluid Fertilizer Foundation • Winter 2015 • Vol. 23, No. 1, Issue #87 Timing, concentrations, and placement in use of fluid fertilizers stressed. effectively use the nutrients we have. The objective posed in the second article is to identify the fertility program components most critical for high- yield corn, including the right fertilizers to use and what combinations and application forms are best. DuPont/ Pioneer, leading the study, identifies the importance of starter fertilizers, the banding of nutrients, the use of multiple N applications, including post-tassel applications of N. It claims its production clinics have facilitated high early adoption rates of practices described in its article. The third article stresses the importance of ear-leaf nutrient balance and concentration in corn leaf tissues. Among the objectives of this University of Nebraska study are accessing tissue concentrations in corn, whether or not existing reference concentrations are still appropriate, and seeing how sufficiency ranges change with growth stage, hybrid, and geographical location. The take-home lesson cited by the soil scientist in charge of this study is when evaluating tissue testing data, make sure the ear-leaf N concentrations are adequate before drawing any conclusions about the adequacy of other nutrients. The final article takes a look at placing P and K at multiple depths. Cotton lint yields were an exception to the study. The experiment demonstrated that placing fluid fertilizers under the row with strip tillage could be achieved and performance with this technique was similar to current nutrient management systems. When comparing 2 x 2 band placement to deep placement, the 2 x 2 band increased early-season cotton growth and produced higher yields. The conclusion of the agronomists managing the study is more data are needed to confirm their findings. “Timing, concentrations and placement in use of fluid fertilizers are stressed.” MAXIMIZE PROFITS Root Growth Stimulator is a synergistic formulation of zinc and ammonium acetate that stimulates the plant to generate a greater volume of healthier roots. The result is a plant with more vigor and greater stress tolerance that produces higher yields and higher profits. learn more at: www.nulex.com Visit your Nulex Distributor or contact a sales representative at 800-831-4815
