Project: 279-15
Title: Characterization of Low Fertility Yields in Preparation for Future Research
Principle Investigator: Carrie Laboski
Objective:
1) To characterize soil test pH, OM, P, K, Ca, Mg, S, Mn, Zn, and B levels in the 0 to 6 in. and 6 to12 in. soil depths where samples are taken from throughout a 50 ft. by 50 ft. area at four low fertility field sites in preparation for future research.
2) To characterize soil test pH, OM, P, and K levels in the 0 to 6, 6 to 12, 12 to 24, and 24 to 36 in. soil depths where samples are taken at grid points on 100 ft. intervals at four low fertility field sites in preparation for future research.

Title: Interaction of Tillage and Nitrogen Fertilizer Use of Corn
Principle Investigator: Francisco Arriaga
Objective:
1) Investigate the impact of chisel/disk, strip-till, and no-till tillage practices on NUE and productivity of corn.
2) Determine the impact of soil temperature and corn residue left on the soil surface in no-tillage on N fertilizer yield response and NUE.
Funding Level: $24,000
Duration: 3 years
Project: 280-15
Title: Validation of Red Clover Crop Nitrogen Credits for Corn
Principle Investigator: Matt Ruark
Objective:
1. Determine the effect of red clover (as a green manure or silage crop), soil type, and tillage on corn yield.
2. Determine the effect of red clover (as a green manure or silage crop) and soil type on corn silage yield.
3. Calculate the N credit for red clover as a function of soil type, crop grown, and tillage used.
4. Assess any drawbacks to the inter-seeding of red clover on wheat yield.
5. Assess the effect of red clover on fall and spring soil nitrate concentrations.

Title: Plant Analysis Calibration for Modern Corn and Soybean Varieties
Principle Investigator: Carrie Laboski
Objective:
1) Assess the effect of varying N, P, K, S, Mn, Zn, and B fertilizer applications on soybean plant nutrient concentrations at R1, R3, R5, and in the harvested grain.
2) Assess the effect of varying N, P, K, S, Mn, Zn, and B fertilizer applications on corn plant nutrient concentrations at V4 (<12” tall), V10, VT, and in the harvested grain
