Tree growth and management in Ugandan agroforestry systems: effects of root pruning on tree growth and crop yield [PDF]

, 2008
Tree root pruning is a potential tool for managing below-ground competition when trees and crops are grown together in agroforestry systems. This study investigates its effects on growth and root distribution of Alnus acuminata (HB & K), Casuarina ...

The Dynamics of Selenium in Dairy Agroecosystems

Exposure and Health, 2022
AbstractEnvironmental selenium deficiency and toxicity can result in Keshan disease and selenosis, respectively. Due to dietary preferences, milk is considered a primary source of selenium, where, in controlled environments milk selenium concentration reflects the selenium provided in fodder to lactating cows.

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Biomass formation and yield performance in diverse multicrops and their potential for biofuel use in short-growing boreal climate conditions

Scientific Reports
Herbaceous plant biomass is an important resource for energy production and an effective strategy to ensure energy supply independence. Growing agricultural plant mixtures (multicrops) contributes to increasing biomass yields, enhancing farm biodiversity,

Deciphering microplastic ecotoxicology: impacts on crops and soil ecosystem functions

Circular Agricultural Systems, 2021
Review on microplastic toxicity in agroecosystems is scarce. Thus, we develop a conceptual model (based on literature to date) that describes various microplastic effects using a size-scale.

Greenhouse gas emissions from croplands of China [PDF]

, 2003
China possesses cropland of 1.33 million km 2. Cultivation of the cropland not only altered the biogeochemical cycles of carbon (C) and nitrogen (N) in the agroecosystems but also affected global climate.

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.
