Abstract: The study was conducted in four sites located in Bagbag, Bulbul, Rizal, Kalinga. The study aimed to determine the above-ground biomass, carbon stock and soil fertility of the four mango plantations site.
The methodologies used includes interview, measurement of trees at the diameter at breast height (dbh), collection of soil samples, 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 showed that the site 2 had the highest above-ground biomass and carbon stock which is equal to 18.51 t/ha, and 8.33 t/ha respectively followed by site 4 (16.07 t/ha, 7.24 t/ha), site 3 (12.29 t/ha, 5.53 t/ha), and lowest at site 1 (7.32 t/ha, 3.24 t/ha).
In terms of soil chemical properties, the four sites revealed that pH, Nitrogen, and Phosphorus are moderately low while potassium was very high which has a mean of 705ppm.
