Crop Residue Study
Purpose:  We will collect traditional crop residue cover percentage measurements using line transect methods and also collect ultra-fine spatial resolution UAS data over the same field. The UAS data will provide means to generate wall-to-wall estimates of crop residue cover percentage of each field, which then can be used to scale the crop residue cover percentage estimation using spaceborne remote sensing technology.

 FMC Agricultural Solutions

  1. 200 Preemergence Mixtures for annual weed control in field corn in high OM soils – 16 treatments x 3 Reps
  2. 201 Preemergence compounds for annual weed control in corn and soybeans – 11 treatments x 3 reps
  3. 204 Preemergence Mixtures for annual weed control in field corn in high OM soils – 14 treatments x 3 Reps
  4. 206 Preemergence Mixtures for annual weed control in field soybeans in high OM soils – 11 treatments x 3 Reps
  5. 242 Experimental compound premixes for weed control and crop safety in soybeans – 14 treatments x 3 reps
  6. 248 Preemergence formulation testing on experimental compounds – 8 treatments x 3 reps
  7. 249 Post emergence formulation testing on experimental compounds   – 14 treatments x 3 reps
Purpose: Evaluate Crop Response of Corn/Soy, overall efficacy of all weed species present (% control), and stalk or root lodging (corn only). In soybean trials, stand counts were evaluated to characterize the treatment effect of heavy rains after chemical application. Notes were taken on symptomology on both the crop and weed species. Soil samples were taken in order to compare results at DPAC with trials implemented at other sites around the Midwest with similar soil properties.

Phosphorus Use Efficiency in Corn
Purpose: Phosphorus use efficiency in corn as impacted by source, timing, and placement.  Low P soils require extra fertilizer P in order to "build up" soil P levels to the maintenance range.  The objective is to explore the potential for maintaining lower soil test P values and minimizing P application rates without sacrificing yield.  This would simultaneously reduce the cost of P applications and risk of causing non-point P losses to surface waters.  We are testing different P sources, timing of application, and placements, and evaluating total P uptake and yield, in exploration of the objective.  Only the low P areas of the field are being utilized for this experiment.
