Changes in Soil Properties after Land Degradation Associated with Various Human Activities in Thailand

This work is a part of the "Waste Land Project" implemented with a view to developing a management plan to improve four different types of degraded lands throughout Thailand. Among them, two sites could be improved by proper fertility management, i.e., sandy soil degraded after lowland shifting cultivation in Northeast Thailand (Somdet, Karasin province) and gravelly silicious deposit after tin mining in southern Thailand (Takuapa, Panga-nga province). Moreover, soil physical properties should be improved together to secure the development of a vegetational cover and sound growth of crops. As for the two other sites, soil fertility was not always a limiting factor on plant growth while soil physical properties posed a more significant constraint, as indicated in the previous paper (Sakurai et al. 1995 : Tropics, 4, 151-172)
