Peat-soil matrix geometry differs greatly from that of the mineral soil and changes with soil-moisture content, mineral content and bulk density. Matrix properties are abruptly altered when virgin peats are drained and cropped. Because of the peculiar moisture regimes and mechanical characteristics of peat soils, each rice-based cropping system has its specific managment requirements. These requirements intensify with increased mechanization and cultivation. Matching peat characteristics and cropping system requirements suggests that traditional rice monocropping on shallow or clayey peat soil is the optimum land use for peat conservation. Growing upland crops accelerates land subsidence and peat loss. The potential for intensive, mechanized, rice-based cropping on peat soils is limited
