Indigenous Soil Potassium (K) Supply, Fertilizer K Use-Efficiency, and K Budgets in Indiana Corn and Soybean Production
Purpose: Evaluate the agronomic efficiency of currently recommended K fertilizer rates; evaluate theoretically improved soil K tests for the ability to predict soil K supply.

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.

- 200 Preemergence Mixtures for annual weed control in field corn in high OM soils – 16 treatments x 3 Reps
- 201 Preemergence compounds for annual weed control in corn and soybeans – 11 treatments x 3 reps
- 204 Preemergence Mixtures for annual weed control in field corn in high OM soils – 14 treatments x 3 Reps
- 206 Preemergence Mixtures for annual weed control in field soybeans in high OM soils – 11 treatments x 3 Reps
- 242 Experimental compound premixes for weed control and crop safety in soybeans – 14 treatments x 3 reps
- 248 Preemergence formulation testing on experimental compounds – 8 treatments x 3 reps
- 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.
