Contribution of mango (Mangifera Indica) to carbon sequestration in barangay macutay and romualdez, rizal, kalinga

The study was conducted in Barangay Macutay and Romualdez, Rizal, Kalinga. The study aimed to determine the soil fertility and contribution of mango plantations to carbon sequestration.

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 9.3. Above ground biomass was computed through the allometric equation developed by Brown, (1997).

Result showed that Barangay Romualdez had higher aboveground biomass and carbon stock which is equal to 37.78t/ha, and 17t/ha compared to Barangay Macutay (28.97t/ha, 13.04t/ha).

In terms of soil chemical properties, the two sites revealed that pH, Nitrogen, and Phosphorus are moderately low while potassium was high which has a mean of 396.25ppm.
