Impacts of ozone on trees and crops

In this review article, we explore how surface-level ozone affects trees and crops with special emphasis on consequences for productivity and carbon sequestration. Vegetation exposure to ozone reduces photosynthesis, growth, and other plant functions. Ozone formation in the atmosphere is a product of NOx, which are also a source of nitrogen deposition. Reduced carbon sequestration of temperate ...

Interactions among leguminous trees, crops and weeds in a no-till alley cropping system

Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

Potential for Greenhouse Aeroponic Cultivation of Medicinal Root Crops

The therapeutic use of medicinal plants such as Echinacea, ginseng and St. John’s wort has gained widespread acceptance in North America in the last two decades. Aeroponic cultivation of medicinal plants have shown great potential for producing root yields that are cleaner, more uniform and faster maturing than can be obtained using conventional soil-based methods. Two pilot-scale commercial A-...
