CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Invasion of Prosopis juliflora and its effects on soil physicochemical properties in Afar region, Northeast Ethiopia

Exporter la citation

Woody species within pastures and savannas are often associated with ‘resource islands’ characterized by higher fertility under canopies trees. The aims of this study were to evaluate (1) the effects of Prosopis juliflora on some soil physicochemical properties and (2) the impacts of Prosopis invasion on soil salinity. For soil physicochemical analysis, a total of 104 soil samples from Teru and Yalo Districts were collected. The soil samples were collected from soil depths of 0–15 cm and 15–30 cm in Prosopis invaded and non-invaded open grazing lands. Invasion of Prosopis had significantly affected soil pH, exchangeable Na+, water soluble Ca2+ + Mg2+, water soluble Na+, and exchangeable sodium percentage in Teru and Yalo Districts (p < 0.05). The invasion of Prosopis significantly increased soil pH (1.5%), but decreased exchangeable Na+ (24.2%), exchangeable sodium percentage (21.6%), and water soluble Ca2+ + Mg2+ (39.9%) than non-invaded lands. Clay content of Prosopis invaded lands was higher by 19% than non-invaded lands. However, sand content of soil was higher under non-invaded lands by 5.6% than Prosopis invaded lands. Most results indicated that invasion of Prosopis had positive effects on physicochemical properties and thus conducive for cereal crops and forages.
