In order to test the nitrogen level of our soil, we first filled the test tube to line 7 with nitrogen extracting solution and added 1 gram of soil to it. We mixed it in the test tube for one minute and then let the sample settle to the bottom. We then took a pipette and extracted the solution from the test tube into another test tube and added nitrogen indicator powder to it. We mixed it and after 5 minutes a light pink color started to develop. The Nitrogen color chart told us that our soil's nitrogen levels were on the low side (0-30 lb/acre). Although the plants growing in our soil looked healthy enough for the level to be considered fine, most plants probably would thrive better in soil with slightly higher amounts of nitrogen.
