We tested how much nitrogen and how much phosphorus we had to put into the buckets by adding more of each and testing until we got 50 mg/L of nitrogen and 3.0 mg/L of phosphorus.These results will help us determine how much nitrogen and phosphate we would have to put in the buckets with the plants so we can test the absorption rates of each plant correctly. Also, we went around and tested the tanks in our science room to see the levels of phosphate and nitrogen in them.
We also tested four types of plants, along growing other plants in our culture pools. The four types of plants we tested were Cattail, Rosemary, Black Krim Tomato, and Pineapple Sage. Our mentors purchased three of each plant for us and we placed each of the three plants in the following: one bucket with both phosphorus & nitrogen added, one bucket with only phosphorus, and one bucket with only nitrogen.
This is our data for the plants we grew in the greenroom. Based on this data we found that Pineapple Sage absorbed both nitrogen and phosphorus the quickest and was best for a potential outdoor testing trial.
