On-Farm Experimentation Community

The OFE-C is a community gathering OFE researchers and practitioners interested in sharing and compiling existing resources online e.g.:
 
    •    guidelines to implement OFE with farmers
    •    examples of OFE, experiences and lessons learnt
    •    statistical solutions to analyze OFE data
    •    best practices to solve specific OFE problems
 
The community focuses on: 1) compiling practical, applied, proven-to-be-useful resources; 2) connecting practitioners e.g., OFE networks, extension personnel, analysts. The objective is to provide OFE practitioners with a “1-go-to” source of information.

OFE Data and Analytics Guidelines

The On-Farm Experimentation Data and Analytics Guidelines spin-off from the May 17, 2021, Data and Analytics webinar of the #OFE2021 Webinar Series. They have been put together by the OFE-C leadership with the help of the webinar presenters and the related working group. Their goal is to propose state-of-the art data, metadata and statistical analysis practices in the on-farm experimentation context.

2022 Publication in Nature Food: OFE to Transform Global Agriculture

Our apologies for not having offered the opportunity to consult the full Nature Food paper in our last communication. The publisher does not allow open access for that kind of paper but it does provide an alternative in the form of this SharedIt link.
 
On-Farm Experimentation Community (OFE-C) co-leads, Simon Cook and Nicolas Tremblay are among the authors of a newly released and highly collaborative Nature Food paper on OFE. This timely work acknowledges and celebrates the diversity of approaches and views on farmer-centric OFE internationally. As the visionary Professor Simon Cook put it, “OFE is the result of accumulated changes across several domains that individually may not be spectacular, but collectively realize a change substantial enough to acknowledge and start articulating.” OFE indeed occurs at the intersection of discussions in agricultural sciences that are necessary to move forward, from best research practices that are inclusive and responsible, to digital technologies that renew spatial analysis and the production of local insights. The paper thesis is that OFE can contribute in a very concrete and pragmatic manner to reshaping relationships between all producers of knowledge — (re) building bridges between researchers, farmers, and other stakeholders of food systems. In many instances change will require proactive support and commitment from institutions. Lacoste, M., Cook, S., McNee, M. et al. On-Farm Experimentation to transform global agriculture.

Recordings of the #OFE2021 Webinar Series are Available

The four OFE2021 webinars recordings are now available at https://www.ispag.org/Events/OFE
  1. Value Creation. OFE creates value for varied stakeholders, value is shared, and scientific disciplines can contribute. May 10, 2021.
  2. People and Processes. People are the real key to digital transformation. Transformation occurs when individual changes scale up through their networks and their organizations. May 12, 2021.
  3. Data and Analytics. Appropriate procedures and well-targeted analytics can be deployed to exploit the valuable data and metadata collected on the farm. May 17, 2021.
  4. Policy Linkages. Currently, initiatives around OFE are happening in spite of funding mechanisms, career paths and norms favoring traditional experimentation. Harnessing the transformational potential of OFE for agricultural sciences and innovation requires more strategic institutional alignment. May 19, 2021.

Unlocking Value by Analyzing Commercial Data

Data from commercial oil palm operations were analyzed for a whole plantation to rank individual blocks according to their ability to respond to applied fertilizer. The ranking was used to guide fertilizer management by diverting fertilizer from unresponsive blocks to those that are more responsive. Although the inferences lack statistical validity, they appear robust from a practical viewpoint. They are easy to evaluate in the field, since they require no upscaling from or interpretation of experimental data. [Oberthür, T. et al. Plantation Intelligence applied Oil Palm operations: unlocking value by analyzing commercial data. The Planter 93, 339–351 (2017)]

Recognizing the mutual dependence of stakeholders to change agriculture

[...] "Top-down political processes such as UNFSS +2 and bottom-up movements should not simply co-exist but converge — and recognize their mutual dependence. The global food system is increasingly complex and interconnected, and coordinating different interests in the face of climate change and other global challenges requires supranational bodies capable of setting guidelines at the macro level. Yet, it is the change coming through social movements and the people on the ground that confers the transformation process legitimacy and ownership, making it attuned to different people’s demands and making it sustainable over time."

OFE in the news: Supporting farmers in their change process

With new digital technologies, scientists and farmers can work together to advance agronomy. By coupling formal agronomic research done by research institutes with change on the ground driven by farmers, the field as a whole can improve. Farmers around the world already experiment on their farms. Not only to support product development for a commercial provider or to accommodate a scientist’s experiment, but to acquire pragmatic knowledge to help manage their farms. This is called farmer-led on-farm experimentation. Read more here.

Can OFE support insurance companies to provide better and cheaper service to farmers?

Climate change has disrupted agricultural cycles and added to the risks faced by farmers globally. Floods, droughts, cyclones, wildfires, and other natural disasters have become more frequent and intense and cause massive destruction and losses. The pandemic-led restricted movement added to farmers’ problems. Crop insurance protects farmers against loss from natural calamities and other risks. However, insurance companies need reliable and timely information on crop area, production, and yield to insure farm operations, customize insurance products for crops and regions, and verify claims. Can OFE help solve this challenge created by climate change?

Tools for OFE

“On-farm research helps farmers make more informed management decisions in their operations for increased productivity and sustainability. […] major barriers to adoption of on-farm research have been the space (larger fields) and the time required to conduct trials during planting and harvest. As these logistical and potentially economic challenges might discourage farmers from engaging in on-farm research and be part of on-farm research networks, a new way to conduct trials was developed that makes use of yield monitor technology and advances in spatial statistics.” Read more about the single-strip evaluation approach (SSEA) here.

New report on Farmer-Centric Data Governance

The potential benefits of digital agriculture are prolific. However, farm data is generally collected by others, and smallholder farmers rely on external resources, like weather data, and proprietary tools that provide specific advisories. Farmers face a paradox: while the use of data holds much potential, control over power, resources, and data governance challenges raise the possibility that farmers do not benefit from their own data. This report contains six Deep Dives and nine Case Studies to provide user-centric approaches to data governance that places farmers and their communities at the center of data gathering initiatives and aims to reduce ...more

Concerns about the transition from Agriculture to Agriautomation fueled by OFE

By: Montana State University On-Farm Precision Experimentation Group We consider the potential endpoint of our research utilizing on-field experimentation to optimize crop production so that it maximizes farmer profits but minimizes pollution from crop production inputs (e.g. cover crops, fertilizers and pesticides). Our research has contributed the ability to fully automate OFE through the use of precision technologies and modern analytics. The conundrum is that agriautomation results in a more ecologically based agriculture that can simultaneously focus on food nutritional density and minimization of pollution, but ultimately removes human and historic mechanisms of knowledge. Agriautomation, the end point of ...more

Observational research often perceived as inferior The main barrier to the publication of observational research is a perceived inferiority to randomised designs with regard to the reliability of their conclusions. This commentary addresses this issue and makes a set of recommendations. It analyses the issue of research reliability in detail and fully describes the three sources of research unreliability (certainty, risk and uncertainty). Two of these (certainty and uncertainty) are not adequately addressed in most research texts. It establishes that randomised designs are vulnerable as observation studies to these two sources of unreliability, and are therefore not automatically superior to ...more

A French network in a problem-solving approach

  Sugar beet production in western Europe is under threat because of the damages due to the impact of viruses that are transmitted by peach aphids. Since 1993, this threat has been under control by the use of neonicotinoids in seed treatments. Due to French regulations, this pesticide has been withdrawn from all crops since 2018. In absence of protection, major yield losses were observed in 2020 (-27.4%) due to early aphid arrivals.

Science and Technology Backyards (STBs) were introduced by China Agricultural University in 2009. It is a farming service model designed to reinforce relational embeddedness between education, research, and extension at the community level to provide agricultural extension and advisory services to smallholder farmers. STB can be considered a hybrid model that combines a top-down approach with bottom-up measures to promote innovation among smallholder farmers. In STBs, technological innovation is supposed to derive from location-specific problem diagnosis and is re-fitted based on local context and farmer demand.

Results of the OFE-C Survey on Social Media Usage

Based on the results below, it seems like LinkedIn is, by a small margin, the preferred social media platform of our group. Due to the spread of use across multiple platforms, it may be good to consider a multi-platform communication strategy, broadcasting content on Facebook, Twitter, and LinkedIn simultaneously. Another outcome of this survey is noticing that there seem to be few students in our group. We encourage you to inform your students about the OFE-C and tell them that they can sign up for free here.

Successful approaches for on-farm experimentation

On-farm experiments are used increasingly in agronomic research because they are commercially relevant, but they can carry greater risks of failure than traditional small plot experiments conducted by scientists. Experimental failures can result from farmer withdrawal, errors in treatment application or harvest, or non-provision of yield data by farmers. This paper describes the development and testing of approaches for on-farm experimentation and concludes which approaches should be adopted to maximise success. The programme of work included the largest on-farm research network in the UK, with farmers conducting around 50 on-farm experiments per year from 2017 to 2019 to compare fungicide programmes in winter ...more

Data-Driven Understanding of on Farm Yield Variation

Agriculture research uses “recommendation domains” to develop and transfer crop management practices adapted to specific contexts. The scale of recommendation domains is large when compared to individual production sites and often encompasses less environmental variation than farmers manage. Farmers constantly observe crop response to management practices at a field scale. These observations are of little use for other farms if the site and the weather are not described. The value of information obtained from farmers’ experiences and controlled experiments is enhanced when the circumstances under which it was generated are characterized within the conceptual framework of a ...more
