Fluid Journal : Early Spring 2011
14 The Fluid Journal Early Spring 2011 at the increase rate of 6 bu/A/yr over the next 20 years. Table 1 shows high yields vs. treatments overview for a 300 bu/A yield plot in Minnesota in 2010. With a geometrically increasing world population and increasing use of world grains for other uses, these types of yields will need to be common in the future. Farmer dollars The economic world for farmers is different today. They experience higher expenses, cash flows, risk, and equipment is more sizable and expensive. Because of this, higher yields become an imperative in keeping the Table 2.

Weeds The curse of agriculture. Little needs to be said here. There should be no surprise at the rapid trend we've seen back to preplant/pre-emerge weed control to supplement Glyphosate programs. The formula is simple: weed/ feed with UAN; weed/feed with NPK suspensions. A couple of good ways to say "goodbye" to weeds. Fluids key Bottom line? Fluid fertilizers and high yields have an affinity for each other: • Placement and timing become very important + FLUIDS • Need to go beyond NPK + FLUIDS • High plant population results in high stalk yields and potential nutrient immobilization + N and S FLUIDS • Starters with big planters + FLUIDS • Late-season applications + FLUIDS • Increase of total nutrient uptake and amounts/day + FLUIDS. Beyond NPK While fluid NPK products have worked to significantly increase crop yields, their combination with other elements is greatly beneficial in increasing crop yields even more. We'll look at a few. Sulfur. The use of sulfur (S) in soils has worked to increase crop yields (note Table 4). It also promotes N/S, P/S interactions. In addition, S becomes a critical nutrient in decomposition of high stalk yields. Zinc is another element that is beneficial in improving crop yields. In an International Plant Nutrition Institute (IPNI) survey, 37 percent of soil samples "The Ecomonic World Market for Farmers is Different Today" head above water, or better yet, maybe even to reaching higher profits. Table 2 shows the impact of a 55 bu/A increase in corn yield on gross dollars per acre in what has become a different economic world today--an increase most sorely needed by the grower during inflationary times. These increased grower revenues also provide significant opportunities for dealers to assist in developing new yield goals for customers. Soil test levels A look at Figure 2 (shown as "P Nutrient Balance Map") demonstrates how P removal rates are exceeding P application rates in Illinois. For the K picture in another state, however, note how K nutrient balance levels for Indiana are significantly improved (Figure 3). This is why it is important for dealers to have a soil testing program to determine PK balance for customer fields. The increase in bushels when adequate Soil Test Phosphorus (STP) exists (Table 3) shows the economies of high P levels. The various tools involved in getting this message to farmers include: • Combine systemic soil testing and yield maps to create nutrient balance maps, by field, for customers • Tell the story: 1. farm call topic
