Fall 2003 The majority of the Midwest Region has excellent crop prospects as the final phase of grain filling begins. While spring and summer rains caused planting delays and flooding losses in many areas, the central grain belt areas have benefited from lack of drought stress. Wheat yields were generally very good. Warm days, but cooler than normal evenings during flowering and early grain fill were positive for initiating a good yield potential. >more

 The High Yield Corn Challenge
This slide set is a brief review of the concept of high yield corn production and a few examples of how PPI has helped promote the challenge among researchers and farmers over the past 25 years. For more information, contact: hreetz@ppi-far.org >more
 2003 Purdue Top Farmer Workshop
Dr. Reetz was an invited speaker for the 2003 Top Farmer Workshop at Purdue University, July 21-23, 2003. This was Dr. Howard Doster's last workshop in a series that has spanned over 3 decades and influenced thousands of farmers as they made decisions on planning their farming operations, equipment decisions, and options for involvement of family members in the operation. Several of the speakers this year came from the wide variety who have participated in these workshops over the years. Howard's legacy will continue as the Top Farmer program moves forward under new leadership of Dr. Jess Lowenberg-DeBoer and others. Most important, it continues in the Midwest farming operations that have been improved through their participation in the Top Farmer workshops. A PDF file of Dr. Reetz's presentation is attached. The full PowerPoint presentation is available upon request. >more
 IMPROVED RECOMMENDATIONS FOR POTASSIUM MANAGEMENT IN MISSOURI CLAYPAN SOILS AFFECTED BY DROUGHT STRESS
Increasing incidences of K deficiency in soybean have been observed in Missouri and other Midwestern states due to several climatic and management-induced factors. In a field trial on a claypan soil in which K deficiency had been observed the previous year, visual K deficiency symptoms were observed, and. application of pre-plant fertilizer K increased soybean yields approximately 20 bu/acre compared to the check treatment. Foliar application of potassium sulfate increased soybean yields compared to a foliar-applied magnesium sulfate check (S0) at three different growth stages during the season. >more
 Management Zones for Nutrient Management
Management zones may be a better alternative than uniform grids for managing nutrients in fields where there is a substantial collection of information and experience to document variability within the field. >more
 Nutrient Uptake by High-Yielding Crops
Daily nutrient requirements increase for crops as yields increase. Even though soil tests may be high enough for meeting total crop needs, the high demand during some critical periods of the growing season may exceed the soil's ability to supply nutrients. Increasing applied nutrients is the best way to ensure these demands are met. >more

 P and K Levels are Critical in a Stress Year
Adequate soil test levels are always important to optimum crop production, but in a drought year, high P and K levels are critical. >more
 Phosphorus and Narrow Rows Boost Soybean Yields
On a low P soil in Minnesota, phosphorus boosted soybean yields under two different row spacings. Drs. Hansen and Rehm reported up to 27% yield increase in 7-inch rows and 31% yield increase in 30-inch rows. >more

 Use K to Improve N Efficiency
A summary of 4 years of Dr. Jay Johnson’s work at Ohio State University shows that increasing soil test K levels helps increase the amount of N taken up by the corn crop, leading to higher corn yields and leaving less of the N in the soil at the end of the season. >more
