2. Rationale and Justification
Midwest:
13-19% yield advantage for corn after soybean.
10% yield advantage for soybean after corn compared to continuous soybean.
What is the advantage for corn soybean rotation in the Midsouth?

3. Rotations

4. Progress… First rotational cycle complete in 2016
Nematode samples currently being analyzed
2016 soil nutrient samples to LSU soil lab soon
Hired Dr. Gurpreet Kaur to work on data analysis, project management

5. Yield following corn vs. soybean*

6. Dr. Gurpreet Kaur Ph.D. Soil Science/Agronomy –University of Missouri
Advisor: Dr. Kelly Nelson
Projects:
SOIL WATERLOGGING AND N FERTILIZER MANAGEMENT EFFECTS ON CORN AND SOYBEAN YIELDS
EFFECT OF FOLIAR BORON FERTILIZATION OF FINE TEXTURED SOILS ON CORN YIELDS
IMPACT OF LONG-TERM PHOSPHOROUS FERTILIZATION ON OLSEN-P AND GRAIN YIELDS IN MAIZE-WHEAT CROPPING SEQUENCE
ETC.

7. Upcoming… Grant contracts still not signed due to delays with USB
- Hopefully signed by end of February…hopefully
Will be sending out data sheets with 2017 crops
Begin work on net returns with Dr. Larry Falconer
We will be sending out project seed ASAP

8. What we need… SOIL SAMPLES!!! ASAP
Production inputs for each crop/treatment:
Chemicals used
Fertilizer applied
Field operations
Etc.

9. THANK YOU
Any Questions?
