Mosaic Corn Fertility Study
K. Mann, L. Besemann and H. Eslinger
MATERIALS AND METHODS
Soil:	Maddock sandy loam; pH=7.4; 1.5% organic matter; soil N 18 lbs/acre; soil P and soil K were very high; soil S was medium.
Previous Crop:	2013 - edible bean, sugarbeet, wheat.
Seedbed preparation:	Spring conventional tillage.
Hybrid:	Croplan 3899VT.
Planting:	May 16 in 30-inch rows.
Plots:	Plots were 40 ft long by 15 ft (6 rows) wide.  The study had four replications.
Fertilizer:	Broadcast and incorporated treatments (see treatments in table 1) May 16, stream bar 20 lbs N/acre as 28-0-0 May 27 and sidedress N as urea June 17 to all treatments except # 1 to bring the total N applied to 215 lbs/acre.
Irrigation:	Overhead sprinkler irrigation as needed.
Pest control:	Harness (2 pt/acre) May 22, Laudis (3 oz/acre) + AAtrex 9-0 (0.5 lb ai/acre) + Destiny (0.05 % v/v) + AMS (1½ lb/acre) June 3, Roundup Power Max (20 oz/acre) + AMS (1 lb/10 gal) June 4.
Remote sensing:	Remote sensing was achieved with an Opti-Sciences CCM 200 Plus chlorophyll meter and a Holland Crop Circle ACS active canopy sensor (normalized difference red edge – NDRE).
Harvest:	November 13 with a plot combine.  Harvest area was the center two rows, 37 feet long.
