Phosphorus fractions status of representative agricultural fields in North Carolina
Journal of Environmental Quality, EarlyView.Abstract Most agricultural soils in North Carolina have high levels of available phosphorus (P), yet little is known about other accumulated P fractions and their associated environmental risks. This study characterized soil P fractions through sequential chemical fractionation of 391 samples (0–10 cm and 10–20 cm) collected from 57 counties across ...

Can conservation drainage practices contribute to climate change mitigation?
Journal of Environmental Quality, EarlyView.Abstract Conservation drainage practices can mitigate water quality impacts of subsurface drainage, but their potential for climate change mitigation remains poorly understood. We summarized processes by which tile‐drained croplands impact climate and assessed potential of conservation drainage practices to alter emissions of the greenhouse gases ...

A Typology of Malian Farming Households
Journal of International Development, EarlyView.ABSTRACT Effective agricultural and rural development policies require a solid understanding of similarities and differences among farm systems. However, in many developing regions, the complexity and diversity of these systems are not well documented yet. In response, this study is aimed at developing a typology of Malian farming households.

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background and aims Bananas are demanding in nitrogen (N) input; therefore, there is a temptation for organic farmers for using synthetic N fertilisers, which are not allowed under organic standards. The aim of our study was to develop a tool that identifies high banana yields obtained with suspiciously low organic N input.
