9 pages, via online journal, Upland farming in Northwest Cambodia has developed rapidly over the last 20 years, with limitations to the plough based system now apparent, including soil degradation and reductions in yield and profitability. A survey was conducted in order to prioritise the main constraints to production, to aid in future research planning, and to identify potential beneficial modifications to the current system. Three hundred and ninety one farmers were interviewed regarding their current farming system constraints, knowledge of conservation agriculture and their future plans in the Districts of Samlout in Battambang Province and Sala Krau in Pailin Province. Perceived major problems in the farming system were extreme climate events such as droughts and heavy rain, declining crop yields, and cash flow shortages, particularly in the pre-monsoon period. This is a plough based farming system, yet 66% of farmers had heard of conservation agriculture, and 59% wanted to learn more about conservation agriculture practices. Two thirds of farmers were interested in how to grow crops in the post-monsoon dry season on residual soil moisture. The survey highlighted opportunities for farmer education and adoption of farming system modifications to improve productivity and sustainability of the farming system in Northwest Cambodia, and assist with climate change adaptation.
10 pages., via online journal., Peri-urban environments, where agriculture and urbanization interact, pose unique challenges for soil management. In Miami-Dade County, Florida USA, this interaction is especially important; a population of 2.7 million lives in an urban county with only 6% of the area zoned agriculture. Miami-Dade County is a major producer of tropical fruit and winter vegetables for the U.S., and is located within the Everglades ecosystem. Relatively little information is known about research and extension within peri-urban environments concerning soil health and management. Ethnopedological work has contributed to ethno-scientific knowledge by bridging the communication gap between scientists and locals concerning soil taxonomies, soil health, and soil fertility management. This study explores mental models of farmers and experts, examining the communication gap concerning soil health and food security. Semi-structured interviews were used to collect data from farmers (n = 19) and experts (n = 13). All stakeholders perceived pressures from urbanization as the main barrier to farmers' ability to continue to produce food, maintain their soil health, and contribute to national food security. The mental models of farmers reveal their ability to continue farming depends on their ability to construct and sustain a system—the soil food value chain. In this system, the farmer generates farm capital from a combination of high quality products, lower quality produce, and culls. This farm capital includes value-added products or soil amendments. However, experts did not perceive their responsibility to include maintaining a system, rather, only improving production. Experts' research and extension focused on improving product quality, increasing yield, decreasing cost of production, and minimizing the environmental impact of production. The mental models of farmers suggest research and extension related to building and maintaining the entire soil food value chain would increase the likelihood the farmers would better care for their soil and be profitable. This research contributes to the literature by recognizing the importance of examining the barriers to soil communication between stakeholders, as well as the importance to include examining soil within the larger food system.

22 pages, via online journal article, Purpose: Soil fertility is decreasing in many parts of Sub-Saharan Africa. To mitigate this trend, various agricultural technologies are available, but their uptake by farmers has been low. Perception of the problem, information exposure, and knowledge play a major role in adoption of technologies. This study assessed empirically the levels of perception, knowledge and information exposure among African farmers as an indicator for potential adoption of soil fertility technologies.
Design/Methodology/approach: The study used survey data of more than 2,400 small-scale farmers selected through random sampling from Ghana, Kenya, Mali and Zambia. The survey investigated socio-economic factors, exposure to media, perception and knowledge of soil fertility and other information.
Findings: Many farmers did not perceive soil fertility as a major challenge, except in Mali; farmers were hardly receiving information on soil fertility from professional agricultural sources, and they often lacked accurate knowledge about soil fertility technologies. Radio was by far the most used information source for farmers.
Practical implications: The study has exposed the need for interventions to increase awareness, information exposure, and knowledge about soil fertility among farmers to strengthen the adoption of soil fertility technologies. It also calls for innovative ways of strengthening extension services through links with radio.
Theoretical implications: The role of communication in the uptake of agricultural innovations is still under-researched, and hence this study exposes the need to investigate in-depth knowledge, perception levels, and quality and frequency of information exposure on various channels of soil fertility management.
Originality: This is one of the few studies empirically measuring perception, information frequency on various channels, and knowledge of soil fertility among small-scale farmers in African countries.
