Inga edulis

Amelioration of degraded rain forest soils by plantations of native trees

background

While 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 & methods

This 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.

Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca

 

Español

Antecedentes

Este estudio se llevó a cabo en Coto Brus, y se enfoca en la restauración de paisajes agrícolas fragmentados dentro del Corredor Biológico Amistosa. El mismo es un área prioritaria para la forestería y la conservación en Costa Rica que ha sido degradrada y transformada por la expansión agrícola durante los pasados 50 años, dejando solo un 25% del bosque original.

Use of the Amazonian Tree Species Inga edulis for Soil Regeneration and Weed Control

background

This article presents research on leguminous tree-based fallows using Inga edulis in Peru.

Research Goals & Methods

Four treatments were compared over a period of nearly 3 years: 1) natural fallow, 2) fallow with I. edulis, 3) fallow with I. edulis combined with a cover crop of kudzu (Pueraria phaseoloides), and 4) continuous cropping of cassava.

Biomass Growth and Farmer Knowledge of Inga edulis in Peruvian Amazon

background

This study develops an equation for diameter-based biomass estimation of Inga edulis. The tree is widely grown in the Peruvian Amazon as a naturally occurring early-successional tree and in small farms and gardens for fruit and fuelwood.

Performance of an Improved Fallow System in the Peruvian Amazon—Modelling Approach

background

This research compares the ecological and economic potential of an improved leguminous tree fallow (using Inga edulis) to the traditional grass fallow (dominated by Imperata brasiliensis) in central Peru.

The Agroforestree Database

About

The Agroforestree (AFT) Database was created in 2009 by the World Forestry Centre and provides specifics and selection guides on both native and exotic agroforestry trees. 

Content

The database contains information about 600 tree species useful in agrofrorestry. Species descriptions include the tree's characteristics, ecology, native range, management, and agroforestry uses. The database is searchable by country, native or exotics species, products and/or services provided, and by the first letter of the species.

Planting Seedlings in Tree Islands Versus Plantations as a Large-Scale Tropical Forest Restoration Strategy

background

This research compares the growth and mortality of 4 tree species (2 native to Costa Rica and 2 native to northwestern South America) in the reforestation of abandoned agricultural land in Costa Rica.

Direct Seeding of Late-Successional Trees to Restore Tropical Montane Forest

background

This study measures seed germination, seedling establishment, survival, growth and foliar nutrient content of five late-successional tree species which were directly seeded into three different habitats representing different stages of succession in tropical montane Costa Rica.The study also compares the costs of direct seeding with locally collected seeds with planting nursery-raised seedlings.
