Biology Soil Sampling

1. Measure a 70 meters long transect at an extended area, with same characteristics such as temperature, day light amount, humidity, and other abiotic factors.
2. Measure and create 50cm X  50cm quadrats every 10 meters along the transect.
3. Take 4 grams of each quadrat sample soil and deposit it on labeled plastic bags.
4. Measure each plant species PH found in the quadrats.

Method:

1. Look for a large area in which you can see biodiversity of plants, choose one in which abiotic factors keep constant.
2. Measure a 70 meters long transect along the area.
3. Make sure to take this measurement at 2’oclock on the afternoon
4. Divide the transect in 7 parts, every 10 meters.
5. In the first division measure a 50cm X  50cm quadrat.
6. Repeat step 5 in every division along the transect. ( Every 10 meters a 50cm X 50 cm quadrat)
7. From each quadrat, take a 4 grams sample of soil and deposit it on labeled plastic bags. (Ex:  10 meters sample, 20 meters sample, 30…).
8. Use a PH meter to measure each quadrats soil PH, and determine each different species found in each quadrat.
9. Record your results on a table determining the PH founded along the transect and how this affected the biodiversity of the plant species.

Conclusion:

Finally, we can see that as the humidity increases, the biodiversity increases also. Specimens located on areas in which the humid conditions are less, the biodiversity is affected by this.
