Change of Sandy Soil Chemical Properties with Azolla microphylla and Quail Manure
Uncontrolled land conversion reduces the available land for plant cultivation. The alternative used for rice cultivation is marginal land, such as sandy soil. However, several constraints led to very low productivity, so it needs proper management, such as adding organic matter. This study aimed to…

From Rice to Oil Palm: the Historical Evolution of Peatland Reclamation in the Berbak Delta, Indonesia
The Berbak Delta in Jambi Province, Indonesia, underwent large-scale peatland reclamation in the 1970s as part of a transmigration program to develop rice fields. Initially, rice production averaged 3–4 tons/ha but declined to less than 1 Mg ha-1 due to the conversion of peat soils into acid…
