The second test we conducted was the Organic Material Test; to determine the amount of organic material in each sample of soil. To determine the value, we added a dissolving acid and water to a soil sample, agitated the sample until it had fully dissolved, and then allowed a 24 hour window before collecting data. The test results are given in a numerical scale of 1-5, where 1 is the lowest amount of organic materials and 5 is the highest amount of organic matter. The test results for Floodplain soil were 3 (T1) and 4 (T2); Forest soil was 1 (T1), 1 (T2), 1 (T3); and Garden soil was 5 (T1) and 5 (T2).
The third test we conducted measured the concentration of Nitrates, Phosphates, and Potassium in the soil. To determine this value, we first added a dissolving acid and water to the water sample, breaking apart the soil. The sample was allowed to settle and the water was siphoned out. The water was then placed in three different tubes, and tested for Nitrates, Phosphates, and Potassium using a test kit (certain tablets were dissolved and using a color key, the samples were measured for High (H), Medium(M), Low(L), or Non-present (NP) Nitrates, Phosphates, and Potassium levels). The test results for Floodplain soil were Nitrate-L, Phosphates-NP, Potassium-M (T1) and Nitrate-L, Phosphates-L, Potassium-M (T2); Forest soil was Nitrate-L, Phosphates-M, Potassium-H (T1), Nitrate-NP, Phosphates-L, Potassium-M (T2), Nitrate-NP, Phosphates-L, Potassium-M (T3); and Garden soil was Nitrate-L, Phosphates-M, Potassium-M (T1) and Nitrate-L, Phosphates-L, Potassium-H
