Amelioration of degraded rain forest soils by plantations of native treesbackgroundWhile much has been studied about the ability of tree growth to improve degraded soils in temperate zones, less is known about the impacts of tree growth on degraded soils in tropical zones. research goals & methodsThis study looks at the effects of trees planted in abandoned pasture land in northeastern Costa Rica, 25 years after that land had been cleared of rainforest. The soil was sampled before tree planting and 4 years after the trees became established. Available with subscription or purchase |
Effects of forest clearing and succession on the carbon and nitrogen content of soils in Puerto Rico and US Virgin IslandsBackgroundConversion of tropical forest lands to agriculture or pasture affects soil organic matter, moisture, and nutrients. This study examines the effects on soil carbon, nitrogen, and moisture at depths up to 100 cm of conversion from forest to agriculture and pasture. Available with subscription or purchase |
Nitrogen Dynamics of Actinorhizal Casuarina Forest Stands and its Comparison with Alnus and Leucaena ForestsBackgroundNitrogen plays a key role in soil fertility and plant productivity. Therefore, in regions in which deforestation has increasingly led to savannization and desertification, afforestation by fast-growing, n-fixing tree species is preferable. This study examines the characteristics of nitrogen fixing trees. Research Goals & MethodsThe nitrogen retention rates of three dry tropical forest tree species were measured, by examining rates of N cycling through vegetation, litter and soil pools.
