Hartley, Mark E. Hodson, Jonathan R. Leake, Steven A. Banwart, David J. Beerling Abstract Land-based enhanced rock weathering (ERW) is a biogeochemical carbon dioxide removal (CDR) strategy aiming to accelerate natural geological processes of carbon sequestration through application of crushed silicate rocks, such as basalt, to croplands and forested landscapes. However, the efficacy of the approach when undertaken with basalt, and its potential co-benefits ...

Rocks for Crops: Agrominerals of sub-Saharan Africa.

A productive and sustainable agricultural system is fundamental to the well being of a nation and a cornerstone of its development. In most of sub-Saharan Africa, more than 50% of the population rely on agriculture for their livelihood, which generally contributes more than 30% of the Gross Domestic Product (GDP). Agriculture is the major source of income, employment, food security and survival for the majority of the population. While agricultural production is steadily increasing in sub-Saharan Africa, the population is growing faster than food production. The result is a net decline in per-capita food production, which contributes to increased food ...
