Title StatementImpacts of land use change on soil properties and soil carbon stock Jo-an T. Ducducan
Physical Descriptionxv, 57 leaves
Summary, Etc.Land use is one of the main drivers of the many processes of environmental change, as it influences basic resources within the landscape, including the soil resources. The objectives of the study were to quantify the SOC stock and nutrient status of the soils under different land uses and to evaluate the magnitude of change on the different soil properties as a result from the conversion of Forest. Nine (9) land uses were selected. Representative soil profile in each land use was examined according to the FAO Guidelines for soil description (FAO, 20016). Soil samples from each depth were analyzed for physical and chemical parameters. Bulk surface soils were also collected to assess SOC stocks, basal respiration and other soil properties. Results showed that among the soil profiles examined, it was in coconut area wherein a relatively higher available P was observed compared to Forest. Forest had a relatively lower total N content, OM, available P and some exchangeable bases compared to coconut, abaca and pasture. The conversion of Forest to other land uses showed different effects in SOC stocks, pH, OM, basal respiration of bulk surface soils. Coffee plantation showed a significantly higher OM (7.08%) thus, higher SOC stocks (171.14 Mg C ha-1) compared to Old Forest but it was comparable to Secondary Forest, Coconut and Mahogany. The quality of soil properties upon conversion from Forest to other land use (e.g Coffee or Coconut) could still be remained favorable for plant growth depending on the management of the area
