Realizing an equitable circular bionutrient economy in the United States
Nutrient recycling potential of excreta for global crop and grassland production
The Art of Scientific Observation
We explore a facet of the scientific method of the Nobel Laureate Barbara McClintock through an artistic process. McClintock’s key scientific insights that she coined the ‘breakage-fusion-bridge cycle’, rest on her observation of maize kernel colors and forms together with the spatial arrangement of chromosomes. These intriguing studies motivated the art project ‘break-fusion-bridge-cycle’ to highlight the role of visual observation in discovery.…
Novelty and Utility
This paper builds on research around novelty and utility to argue that the value of arts thinking should be applied in the generation of scientific questions. Arts thinking is often playful, less goal oriented, and can lead to new modes of questioning. Scientific thinking often solves an existing question, serves a purpose in solving the question, and must be predictable. The “problem of the problem” is that asking creative questions is the linch…
Undisciplining the university through shared purpose, practice, and place
Interdisciplinary scholarship and education remains elusive at modern universities, despite efforts at both the individual and institutional levels. The objective of this paper is to identify the main motivations that bring different disciplines together in joint research and identify some of the obstacles to that coming together. Here we propose that shared purpose (why do I participate?), practice (how do we interact?), and place (where do we i…

Persistence of soil organic matter as an ecosystem property
Anthropogenic soils in the Central Amazon
Amazonian Dark Earths (ADE), one of the best-known examples of anthropogenic (man-made) soils, are the result of Amerindian settlements in the pre-Columbian period. ADE are highly variable in terms of their size, shape, depth and physical and chemical make-up. Scholars tend to divide ADE into two categories: terra preta and terra mulata. The former are dark and highly fertile soils replete with ceramic shards, indicating former areas of habitatio…
Biochar—One way forward for soil carbon in offset mechanisms in Africa
Charcoal Making in the Brazilian Amazon
Terra Preta Nova – Where to from Here
Amazonian Dark Earths
Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed terra preta or dark earths. These soils are presently an important agricultural resource within Amazonia and provide a model for developing long-term future s…
