One perceived cost of integrating winter cover cropping in maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] rotation systems is the potential negative impact on soil water storage available for primary crop production. The objective of this 3-yr study was to evaluate the effects of winter cover crops on soil water storage and cover crop biomass production following no-till maize and soybean rotations. Locations were near Brule (west-central), Clay Center (south-central), Concord (northeast), and Mead (east-central), NE. Treatments included crop residue only (no cover crop) and a multi-species cover crop mix, both broadcast-seeded before primary crop harvest and ...

In previous work, Isosorbide Distillation Bottoms (IDB), and other isosorbide and soybean based materials with similar properties were shown to act as antistrips in a polymer modified warm mix asphalt (WMA) at a 0.75% dosage level both through visual observations and statistical analysis of Hamburg Wheel Tracking Device (HWTD) test results. Because of this evidence, there is an interest in how specimens produced with isosorbide and soybean bio-derived chemical additives would perform in the dynamic modulus test, as this is the main input used in AASHTOWare Pavement ME in the prediction of rutting performance. The main objective of this ...
