Table 1. Results from the nitrate and phosphate test done on water obtained from growth and no growth areas.
(-) indicates that the levels were too low to record, whereas (+) indicates levels signifying absolute presence.
| Water sample | Growth | No growth |
| Nitrate test | – | + |
| Phosphate test | – | + |
There was no trouble obtaining the data because the samples all followed a similar pattern, the no growth samples had more nitrates and phosphates and showed a reading in the photometer, whereas the growth areas had minimal amounts that were so minuscule that the photometer could not read the levels.
The results were as expected, where there was growth the levels of phosphates and nitrates were low because the plant uptakes the nutrients. Whereas, no growth samples had more nitrates and phosphates because the samples were collected far from the plant.
