[Scene opens with a shot of young soybean rows with the Soy Masters badge and "Field Notes" overlaid on it. Drum and guitar music plays in the background. The text "How Do Soybeans Impact Available Nutrients for Following Crops?" shows. Scene switches to Dr. Jeff Schoenau (Professor of Soil Fertility, University of Saskatchewan) in a hotel lobby, speaking to camera.]
JEFF: Some research work that we did at the University of Saskatchewan compared the availability of nutrients on different legume residues.
[Scene shows the test field with small patches of different crops.]
JEFF: And that included, soybeans, pea, and lentil. And in this work, we grew soybean, pea, and lentil at 4 different sites across Saskatchewan.
[Scene switches back to Jeff in the hotel lobby, speaking to the camera.]
JEFF: And we looked at the nutrient uptake by the soybean in comparison to the pea and lentil.
[Scene shows a close-up shot of a newly emerged soybean. It then switches to a ground-level shot of a field of newly emerged soybeans.]
JEFF: And then the following year we grew wheat and canola and looked at the nutrient uptake by those crops and the yield.
[Scene switches back to Jeff in the hotel lobby, speaking to the camera.]
JEFF: And we also followed the supply of available nutrients in the soil, in those stubbles, using PRS (Plant Root Simulator) probes. So what we found is that amongst the 3 different legume stubble types, there wasn't much difference in the release of available nitrogen, phosphorus, secondary nutrients, or even micronutrients, amongst the different legume stubble types.
[Scene shows a row of lentils. The scene then switches to a close-up of a hand touching a freshly emerged lentil plant.]
JEFF: And this was shown as well in the uptake of nitrogen and phosphorus and the other nutrients by the following crop.
[Scene switches back to Jeff in the hotel lobby, speaking to the camera.]
JEFF: And even the yield. So overall, there wasn't much difference, which said to us that in terms of adjusting the fertilizer rate of application of nitrogen and phosphorus,
[Scene shows a mature soybean field.]
JEFF: making alterations between pea and soybean stubble, there didn't seem to be much need for a large adjustment.
