Below is a link to a YouTube video I compiled of a typical AIM plot. My personal focus this season was mainly on the soil information. For each site we dug a soil pit and collected different data from the pit. The pit had to reach 70cm, and this could take up to three hours to reach. In the video I show you a couple different angles of the pit, the tools I used to dig and shape and collect samples with, a shovel head with 5 different soil horizon samples on it, and lastly close up video of taking an effervescence sample.
