Soil characteristics in an exhumed cemetery land in Central Singapore.

Soils in urban landscape act as a component for various ecological functions. For sustainable urban greenery and effective management of urban ecosystems, evaluation of soil quality is of paramount importance. A study was undertaken to assess the existing soil quality and determine spatial soil variability of an exhumed cemetery land in central Singapore, so that systematic and sustainable soil management practices could be implemented for its conversion into an urban park. A stratified sampling method was followed to collect the soil samples from three depths: 0-30, 30-50, and 50-100 cm. An integrated soil quality index (SQI) approach was undertaken to monitor the changes in soil properties. The visual assessment showed the uniformity of horizon distribution of the soil profiles across the park and the soils had acidic pH ([Formula: see text] 5.2) and moderately high bulk density ([Formula: see text] 1.6 g cm
