Test plots are a ton of work!
In the mid 1990's through early 2000's I was teaching Agriculture in a district where the FFA chapter had been blessed with the donation of 240 acres. It was donated about 5 years prior to my start there. There was a 40 acre tract of good Mississippi bluff and the farmstead, a 80 acre tract of good Mississippi bottom land, and a 80 acre adjoining tract that was lighter soil. When it was donated in the man's will he was very specific. He did not want it going to the school as I believe he felt they would squander it. He placed it in a 25 year trust separate from the school for the benefit of the FFA chapter. The school was to have nothing to do with it. There were three trustees, a local banker, a local farm operator, and the FFA advisor. We met at the bank for trustee meetings. It was a 25 year trust and at the end it was to be sold with 1/3 to the FFA chapter, 1/3 to the city park, and 1/3 to Iowa State University Agriculture. He was very specific in that during the 25 years the farm was to be operated as a research farm for educational purposes. Prior to my arrival for whatever reason the court was petitioned with an objection. A judge forced the sale of the 40 acres that had the home and buildings but the FFA chapter kept the 160 acres. It was decided that 160 acres was too large to run as a research facility being it was 7 miles from the school. The rear 80 acres of lighter soil was farmed on a traditional basis with a 50/50 corn bean rotation. The front 80 acres that was the better soil was divided into (4) 20 acre plots. Of course with the roads and exhibition areas they were closer to 16 acres or so. Two of the plots were traditional seed variety plots with one beans and one corn. We had space for 26 varieties 6 rows wide with a 6 row check strip between each two. That was 40 times we had to empty boxes on an old JD 7000 planter for each plot and 40 dumps in the weigh wagon with moisture and test weight tests. This was all done by high school FFA members. I just oversaw it. That was the point of education. The other two "20 acre" plots varied from nitrogen rate tests, population tests, tillage tests, herbicide tests, and others.
I know the work a test plot takes
