Seeded LTER Main Site Treatment T4 all replications (6, 5, 3) on 03/07/25, and (4, 2, 1) on 03/09/25 with Byron Seeds Medium Red Organic Clover at 12 lbs/A.
(PLS of 48.375 makes the new target 24.81 lbs/A) Actual application was 335 lbs total making the application rate 24.8 lbs/A (T4 total is 13.5 acres due to the prairie strips).
A pure live seed calculation was done to calculate amount of seed per acre needed to achieve the 12 lbs/A of pure live seed.
The calculation equaled 25 lbs/A seeding rate to achieve the 12 lbs/A of pure seed (see papers attached).
Clover was seeded with John Deere 5220 tractor traveling at 5.0 mph, gear B3 at 2000 rpm, and Gandy Air Seeder (15 ft boom length) equipped with 8 deflectors spaced 22.5 inches.
Fan pressure is approx. 11oz/in.
Gandy motor setting was 2.3 with the red metering wheels in and the gates on the Gandy were in the first position.
Boom height was 23 inches from the ground, bottom of the defectors were 20 inches from the ground.
