Assessment of natural vegetative contour strips for soil conservation on shallow calcareous soils in the central Philippines: accomplishment report for the period Nov. 2000 - July 2003

Exporter la citation

While a good understanding exists of the effects of low-cost natural vegetative contour strips (NVS) in deep acidic soil environments, little is known about the benefits and constraints of using NVS under severely degraded calcerous soil condition. Calcerous soils cover about 20% of the total land area of the philippines, and are also wide-spread in other parts of Southeast asia. They therefore, characterize an important environment that millions of upland farmers depend upon for a living in the region. Shallow calcareous soils are particularly common in the Central Phillipines covering more than half of the total land area of the Visayan islands. Under shallow soil conditions, the effects of soil scouring can be severe because the entire soil may be removed down to the parent rock material.
