Very large quantities of carbon dioxide (CO2) will need to be removed from the atmosphere over the course of the next century or two to stabilize Earth’s climate at a safe temperature. A handful of C-drawdown approaches are available to perform this task, three of which involve soils: increasing stocks of soil organic matter (SOM), […]
This project addresses breeding, varietal selection, management practices, processing, or marketing practices to increase food quality, nutrition, safety or access. In a previous study, we demonstrated that tomato fruit grown under an organic fertilizer regime had higher phytonutrient content. Thereafter, using a comprehensive transcriptome analysis we tested the following hypotheses : 1. Growth under organic […]
In an ongoing BIOAg supported study, it has been shown that tomatoes grown with organic nitrogen sources had higher phytonutrient contents than those fertilized with readily available nitrogen. It is hypothesized that improved nitrogen cycling may be the underlying cause of these observed differences. In addition, defense compounds are enhanced in tomatoes grown with organic […]
In previous studies, we showed that apples, strawberries, and tomatoes grown with organic nitrogen fertilizer sources had higher phytochemical contents than those fertilized with readily available sources of nitrogen. It is also possible that increased pest herbivory in the field stimulates plant defenses that elevate these phytochemicals in organic crops. To test the relative contributions […]
