Abstract: This study was conducted to assess the soil fertility status of selected Community-based Forest Management sites in Kalinga. Soil samples were collected and analyzed for the different soil fertility indicators such as soil pH, Nitrogen (N), Potassium (K), and Phosphorus (P). Results showed that the CBFM project in Pinukpuk, Kalinga had higher Nitrogen (N) content compared to the CBFM site in Tabuk City, Kalinga with an average of 1.548 and 1.354 respectively. In terms of Phosphorus (P) content, Pinukpuk site had an average of 4.647 while Tabuk City had an average of 3.4. For the Potassium (K) content, Pinukpuk site had an average content of 194.90 while only 48.71for the Tabuk City site. In terms of pH, the sites revealed that almost the same pH value of 5.159 and 5.114 respectively. CBFM site in Pinukpuk, Kalinga tremendously overturn the CBFM site in Tabuk City, Kalinga due to its higher plant biodiversity coupled with the presence of native tree species in the area as compares to that in Tabuk City CBFM area.
