This document discusses best agriculture practices on peatland for community livelihood. It covers two sessions from a regional project conference held from May 16-18, 2012. The first session discusses the chemical and physical properties of peat soil, including low pH, nutrients, and bulk density as well as high carbon nitrogen ratio, cation exchange capacity, porosity, and water table. Addressing these challenging properties is important for agriculture on peatland.
