Name: 28% CLARK Six Row Fertilizer Applicator
- Uses Material Description: The CLARK six row 28% applicator is made up of 7 coulter units with direct injection systems controlled by nozzles, where the two outer rows units are applying half rate and the 5 inner row units apply a full rate. The outside two row units travel in the same guest row twice so by applying half rate they essentially apply the full rate after the second application. This applicator is controlled by a John Blue (ground driven) pump that is fed into a manifold were it is dispersed evenly to all 7 lines.

2011-06-15 Fertilizer Application Fertilized the LTER Main Site treatment T2, replications 1, 4, 3, 2, 5, and 6 with 28-0-0 liquid fertilizer. Urea-Ammonium Nitrate (28-0-0) was applied at a total rate of 37 gal/A. Since 28% fertilizer weighs 10.65 lbs/gal, the 37 gal/A was the same as 110 lbs N/A. Fertilizer was knifed between the rows of corn using a 15' liquid fertilizer applicator. Plot T2R1 was fertilized completely on 13 Jun 2011. Plots T2R2, T2R3, and the west 1/2 of T2R4 received approximately 1/2 of the total fertilizer on 13 Jun 2011; however, at that time it was noticed that the volume of liquid which was being applied did not match the desired rate. Exploration determined that there was an equipment error and that the metering pump was not functioning correctly. At that time, it was determined that only about 1/2 the total rate had been applied. On 15 Jun 2011, a second application was made, to provide the amount which was missing, to make the total application equal to the 37 gal/A rate. The order of application for the entire treatment was T2R1, T2R4, T2R3, T2R2, T2R5, and T2R6. It is believed that the equipment error occurred approximately toward the end of plot T2R1 (rows 13-30 from the east edge of T2R1, fertilized on 13 Jun 2011) and the beginning of T2R4, although this could not be determined precisely.
