Abstract: The study was conducted in the reservation area of the Kalinga State University located in Tawi, Bulbul, Rizal, Kalinga. The study aimed to determine the above-ground biomass and carbon stock of the reservation area.
The methodologies used includes, measurement of trees at the diameter at breast height (dbh), gathering of corner points with the use of GPS and processing of data in Arc GIS. Above-ground biomass was computed through the allometric equation developed by Brown, (1997).
Result of the study revealed that site 6 had the highest biomass (388.59 t/ha.) followed by sit 3 (187.05 t/ha.), site 5 (169.93 t/ha.), site 4 (131.86 t/ha.), site 2 (102.27 t/ha.)And site 1 (76.40 t/ha.). Comparison of carbon stock, site 6 had the highest carbon stock which is equivalent to 174.87 t/ha. Followed by site 3 (84.17 t/ha.), site 5 (76.47 t/ha.), site 4 (59.34 t/ha.), site 2 (46.02 t/ha.) and lowest at site 1 (34.38 t/ha.)
Majority of the sites were fall under the optimum pH value. The study revealed that the reservation area has a good nitrogen level because majority of the species are nitrogen fixing trees (ipil-ipil). The reservation area has a mean of 14.5ppm. Based on Phosyn Chemicals Limited (1987, cited by Palijon, 1998), the guideline level for phosphorus is 50ppm. The study site is described as moderately low level of phosphorus.
Result of the study revealed that the study site has a high level of potassium content which has a mean of 509ppm. Based on Phosyn Chemicals Limited (1987, as cited by Palijon, 1998), the guideline level for potassium is 200 ppm.
