Despite decades of interventions, soil degradation in Ghana persists, raising policy concerns about the effectiveness of current approaches, which have largely focused on fertilizer use and its on-farm adoption. This underscores the need for a broader, systemic understanding of the enablers and barriers within the Ghanaian soil health system, and how soil health can be more effectively managed. This study looks at soil health...

In this study, we show that, although policy actors perceive the fertilizer subsidy package in Ghana as part of the enabling environment to facilitate the scaling of subsidized fertilizers, not all farmers have equal access to the intervention. There is quantitative evidence, based on cross-sectional surveys, of the factors that correlate with access to subsidized fertilizers, but it is unclear what dynamic mechanisms are at p...

Over the past decades, agricultural extension services in Ghana have promoted a variety of practices to restore soil fertility. However, several studies have shown that there is a scaling conundrum, as the promoted practices have been met with persistent low adoption. The existing quantitative evidence helps to identify the cognitive and sociodemographic variables that influence individual farmers’ adoption of soil fertility p...

Mineral phosphorus (P) fertilizers support high crop yields and contribute to feeding the teeming global population. However, complex edaphic processes cause P to be immobilized in soil, hampering its timely and sufficient availability for uptake by plants. The resultant low use efficiency of current water-soluble P fertilizers creates significant environmental and human health problems. Current practices to increase P use eff...
