Phosphate is one of the main ingredients in fertilizer. Phosphate helps plants grow stronger roots and allow them to produce seeds. Seeing that
has less phosphate than the two fields might be because the parks are fertilized which may mean that fertilizer runoff from the areas around Nose Hill hasn’t dramatically affected it. Nose Hill Park
pH is the measure of the acidity or basicity of a solution. If the soil is too acidic, then plants will not thrive in that environment. On the other hand, if the soil is too basic, then plants won’t thrive there either. Acidic soil is typically caused by a natural force, rain. But seeing as
doesn’t receive to much of that, Nose Hill should have a pretty non acidic soil pH level. The pH at Nose Hill, as well as our two other fields was 6. With the neutral pH being at 7, we found that the soil at all 3 places is one of the best environments for plants to survive. Calgary
Nitrates helps plants grow above ground. We found no nitrates in the soil samples. Originally we thought this was weird because plants need nitrates, but then we came to the conclusion that we found no nitrates in the soil samples because the plants in all three places had taken up and used the nitrates in the ground.
Ammonia is decomposed matter that has gone through the process called ammonification. We found that
had more ammonia than the two fields. This may be because at Nose Hill Park , nobody picks up the dried leaves and such, therefore they are left to decompose, resulting in more ammonia in the soil at Nose Hill park. In the contrary, the fields may have less ammonia because people rake up the leaves and decomposing matter rather than letting it decompose and turn into ammonia. Nose Hill Park
