A Practical Guide to On-Farm Pasture Research

A guide in 6 steps: 1) define the study question; 2) choose treatments; 3) how and where to conduct the study; 4) choose variables to measure; 5) conduct the experiment and analyze the results; 6) share your results.  

A Practical Way to Share Data With Confidence

Farmers often feel that they do not get the value back after sharing their data. The GODAN (Global Open Data for Agriculture and Nutrition) organization has recently made available an Agricultural Data Codes of Conduct Toolkit. By using the toolkit, they can understand and control what is done with the data, who can do what, and so on. They feel engaged, considered and this strengthens the farmer value structure. The toolkit allows farmers to select clauses that might be of relevance and to easily produce a printable and saveable Code of Conduct that provides the conceptual basis for general, scalable ...

A Reflexion on a New OFE-Based Agronomy

Accurate interpretation is the key to getting value from OFEs—good interpretation helps farmers learn more from each OFE, and manage with greater certainty as a result. Sadras and co-authors [Making Science More Effective for Agriculture: Advances in Agronomy, 163:153—77] call for an expanded role for agronomic logic to solve global crop production challenges. Yet many OFEs generate insights of complex and variable crop behaviour that call for stronger engagement of agronomy with these farmer-driven operations. In fact, some data scientists believe analysis can proceed without theory—an approach Taguchi adopted for dealing with complex systems. As we ...

Business Meeting Minutes - On-Farm Data Sharing (OFDS) Community at ICPA

26 June 2018, Montreal, Quebec, Canada   The meeting started at 6:35 pm with 11 people in attendance. After introductions, a discussion occurred about changing the focus of the OFDS Community from sharing of field-scale trial data collected on production farms to methods, protocols and analysis of on-farm experimentation.   The rationale for the change provided by Nicolas Tremblay and Tom Morris was that the proposed new Consortium for On-Farm Experimentation with leadership by Simon Cook would benefit from having a scientific home in ISPA, and because some of the objectives of the OFDS group have been shifted to an OFDS Working Group in ...

Crowdsourcing Uses and Opportunities in Agriculture

Crowdsourcing, understood as outsourcing tasks or data collection by a large group of non-professionals, is increasingly used in scientific research and operational applications. Close connections with the farming sector, including extension services and farm advisory companies, could leverage the potential of crowdsourcing for both agricultural research and farming applications. [Julien Minet, Yannick Curnel, Anne Gobin, Jean-Pierre Goffart, François Mélard, Bernard Tychon, Joost Wellens, Pierre Defourny. Crowdsourcing for agricultural applications: A review of uses and opportunities for a farmsourcing approach. Computers and Electronics in Agriculture 142, Part A (2017): 126-138.]

Designing Your Own OFE - Bramley

Have a look at this classic 2006 guide (Designing Your Own OFE - Bramley) for farmers and their advisers on precision agriculture-based field experiments - their design, and the important issues to be considered in analysing the results. The guide was published by the Grains Research & Development Corporation (GRDC) of the Australian Government.  

Disparate Big Data in Systems Agriculture

In our data-rich world, identifying optimal systems for sustainable intensification or diversification is lacking a data management system across spatial and temporal resolutions including workflows, interpretation methodology, and a delivery structure. This paper offers solutions for developing a platform for bridging component parts (encompassing multiple scales and disciplines) to analyze system functionality for greater resiliency. [Tulsi P. Kharel Amanda J. Ashworth Phillip R. Owens Michael Buser. 2020. Spatially and temporally disparate data in systems agriculture: Issues and prospective solutions. Agronomy Journal 112 (5): 4498–4510. https://doi.org/10.1002/agj2.20285].  

Ecosystem for FAIR Data for Cross Domain Research

Have a look at a very packed page on the challenge around data with clarifications on the lexicon for terms such as “metadata, interoperability, governance, cleaning and big data.” We learn that “over the last two years, a CODATA-led pilot project has developed, tested and refined methods for aligning metadata specifications, taxonomies and ontologies to address these problems in a consensual fashion.”  

Engage farmers in research

The one-size-fits-all approach of research has had success but advances are slowing. “How well crops and livestock grow depends on the interaction of genes, management and environment. As weather patterns fluctuate, gains in production will depend ever more on innovating in context. Big knowledge flowing from institutes to farm must be complemented by local knowledge.” Small-scale agricultural innovation will boost yields and protect the planet. See this Nature Comment.  

Establishing the Precision and Robustness of Farmers’ Crop Experiments

Precision farming experiments are generally incompatible with conventional statistical methods and alternative models of response variables (e.g. yield) must be estimated if the effect of the management decision is to be distinguished from other sources of variation. The model-based statistical analyses of these experiments require assumptions regarding the variation of the response variable. When these assumptions are inappropriate (e.g. if the correlation between response variable measurements is poorly modelled) then the inferences from the experiments can be unreliable. Marchant, B. et al. Establishing the precision and robustness of farmers’ crop experiments. Field Crops Res. 230, 31-45, doi:10.1016/...

Evidence Synthesis in Agronomy

There is a need to shift the focus from individual studies to the accumulating body of evidence concerning the agronomic and environmental benefits of innovative farming practices. Systematic reviews, evidence mapping, on-farm research, and meta-analyses are available for the integration of results but they are not yet used as frequently as one might expect. Both qualitative (systematic reviews, evidence maps, farm surveys) and quantitative syntheses (meta-analyses, modeling) have been published in a special issue of the European Journal of Agronomy. [Makowski, D. Editorial of the special issue “Evidence synthesis in agronomy”. European Journal of Agronomy 122 (2021) 126183. ISSN 1161-0301. https://...

Farmer-based Research program on the Falkland Islands

On-farm experimentation (OFE) and precision agriculture technologies could be a potent mix for driving change in agricultural systems. Many of us recognize the significant opportunity in large, tech heavy and digitally enabled cropping enterprises. However, most of the world’s agricultural land is characterized by extensive, tech-poor livestock systems (LS). “OFE in LS” could help to introduce appropriate digital technologies in a way that is meaningful to farmers. Have a look at this recording from Matthew McNee, agronomy advisor in the Falkland Islands.  

Farmer-Led Innovation Network in the UK

A Farmer-Led Innovation Network (FLIN) was established in October 2018 to share knowledge and experiences and provide a collective advocacy voice for farmers in the UK. The main aim is to understand, learn from and “power-up” farmer-led innovation initiatives and increase their economic, environmental and social impact across the industry.  

Farmer-Led Research Webinar

A Farmer-Led Research Webinar was conducted last month by the School of Environmental Design and Rural Development, University of Guelph. The webinar mentioned the need for scientific rigor, yet keeping a balance between practical and robust protocol, on the one hand, and keeping data collection and research flexible, on the other hand. The recording is now available.  

Farmers’ experiments and scientific methodology

“Testing of only one variable at the same time,” has quite recently been described as one of the criteria that a scientific field trial has to satisfy. In projects involving cooperation between farmers and scientists, scientists have sometimes been “frustrated” with farmers whose experiments have not satisfied the one-variable requirement. Reportedly, this is “one of the points that has [led] research station scientists to dismiss farmer innovation.” This study investigates methodological and philosophical issues pertaining to farmers’ experiments such as the choice of interventions to be tested, the planning of experiments, and the ...

Guide to Farmer's Crop Trials from ADAS

By working together with other farmers, suppliers, agronomists and scientists, farmers can use their own trials to bring fast learning, new findings and best practice for themselves and the industry at large, an approach ADAS calls “Agronōmics”. GPS and other modern technologies, along with thorough trial protocols, can make farm trialling straight forward and routine. Decisions and innovations can then become thoroughly validated and tailored to real farming conditions. This Guide to Farmer’s Crop Trials outlines processes leading to successful farm-trialling and how to avoid the pitfalls.

The handbook delivers guidance on how to form effective interdisciplinary and multi-stakeholder teams and how to plan, implement and analyze system experiments. The Sustainable Agriculture Research and Education (SARE) program is a decentralized competitive grants and education program.  

Harmonization of Heterogeneous Spatial Data

Heterogeneous spatial datasets are those for which the observations of different datasets cannot be directly compared because they have not been collected under the same set of acquisition conditions, with consistent sensors or under similar management practices, among others. This paper details and compares four automated methodologies that could be used to harmonize heterogeneous spatial agricultural datasets so that the data can be analyzed and mapped conjointly. [Leroux, C., Jones, H., Pichon, L. et al. Automatic harmonization of heterogeneous agronomic and environmental spatial data. Precision Agric 20, 1211–1230 (2019). https://doi.org/10.1007/s11119-019-09650-0]    

How do data and analytics from on-farm trials should be dealt with?

The OFE-C is seeking professionals and researchers dealing with data from on-farm experimentations or their analysis. We want to identify requirements and valid procedures leading to guidelines and eventually policy development. Volunteers will help select topics to cover in a webinar sometime this spring and the best presenters for that purpose. The workload will not be substantial. Please volunteer or suggest someone you know here.  

How do Research Protocols Need to be Adapted to Farmers Priorities?

Do farmers and researchers have the same criteria for gauging the success of an experimental trial in commercial conditions? Having the priorities of the farmers in mind, how should the researchers adapt their experimental approaches and analytics? White peg research or else? We are starting a structured thinking process on this question in order to frame the debate and develop consensual guidelines. Should you have elements to provide or want to be involved, drop us a line here.  

How do we enact co-innovation with stakeholders in agricultural research projects?

Mobilising co-innovation involves a complex interplay between contextual forces and facilitation processes. This interplay shapes the core co-innovation processes of joint framing, testing of solutions and creating new knowledge. The interplay between contextual and facilitation processes requires an adaptive approach to research design and management. [Ingram, J., Gaskell, P., Mills, J. & Dwyer, J. How do we enact co-innovation with stakeholders in agricultural research projects? Managing the complex interplay between contextual and facilitation processes. J. Rural Stud. 78, 65-77, doi:10.1016/j.jrurstud.2020.06.003 (2020).]

Multi-criteria decision analysis in agriculture rarely consider important elements

The study of a corpus of 954 articles published by INRA scientists from 2007 to 2017 concludes that MCDA studies will need to include participatory science to involve stakeholders (i.e., public authorities, governmental agencies) and end users (i.e., farmers, producers, industry, consumers) in the construction of the multi-criterion evaluation but also in the resulting decisions.  

Nobel laureate shows the power of digital agriculture and on-farm experimentation

Michael Kremer got a share of the 2019 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for his work on experimental approaches to alleviating global poverty. He notably showed innovative uses of randomized control trials to answer key development questions related to agriculture. Kremer recently gave a lecture at the FAO (Food and Agriculture Organization of the United Nations) to show how mobile technologies and digital agriculture can create innovations reaching out to smallholders as well. Kremer also addressed the role of higher-resolution weather information, customized pest-control advice and the opportunities to improve supply chains and extension services. ...

The recording of the 90-minute workshop which gathered about 300 participants can be found here.    

Repeated designs not sufficient to evaluate treatment effects accurately in OFE

The outcomes of on-farm experiments can support farmers’ decision-making processes, while inappropriate procedures would result in incorrect interpretations. Conventional statistical approaches (e.g., ordinary least squares regression) may not be appropriate for on-farm experiments because they are not capable of accurately accounting for the underlying spatial variations in a particular response variable (e.g., yield data). A combination of a repeated design and an anisotropic model is required to improve the precision of the experiments. [Tanaka,T.S.T. 2020. Assessment of research frameworks for on-farm experimentation through a simulation study of wheat yield in Japan . Preprint 12741.]  

Seeking Great Photos: “Doing” On-Farm Experimentation

If you have pictures that eloquently illustrate this idea that you are willing to share, please drop us an email. It will be greatly appreciated!  

Specific Treatment Responses in On-Farm Precision Experimentation

Site-specific information about crop responses to agronomic treatments is needed. Geographically weighted regression was applied to generate local regression coefficients, which were used to delineate response zones in fields. This is a way to reevaluate expectations on variable rate prescriptions guided largely by soil and variability. Trevisan, R.G., Bullock, D.S., Martin, N.F. Site-Specific Treatment Responses in On-Farm Precision Experimentation. Preprints 2019, 2019020007 (doi: 10.20944/preprints201902.0007.v1).  

The Analysis of Agricultural Experiments: A brief History

From Fisher in 1926 to nowadays much needs to change in the analysis of agricultural experimentations. Charles (2021) guest editorial in The Journal of Agricultural Science focuses on the 20th century. Even before the digital age, experiments intended to resolve difference questions were replaced by experiments designed to answer questions about the magnitude of differences and responses to treatments. The review raises a question: namely is it time to revisit Bayesian statistics on the grounds that visionaries and innovators are prone to subjectivity? [Charles D. (2020). Guest Editorial: The analysis of agricultural experiments: a brief history of the techniques of the 20th century. ...

The Farmers’ Perspective on Data Governance

Fragmented and unclear data governance arrangements may weaken farmers’ willingness to adopt digital solutions. This, in turn, may reduce the availability and accessibility of agricultural data for policymaking, for the agricultural innovation system, and for developing services for farmers. This OECD report focuses on farmers’ concerns around access, sharing and use of agricultural data and explores whether and how existing policy frameworks and other sectoral initiatives can help to foster greater trust. [Jouanjean, M., et al. (2020), “Issues around data governance in the digital transformation of agriculture: The farmers’ perspective,” OECD Food, Agriculture and Fisheries Papers, ...

The Long-Term Agroecosystem Research Network (LTAR)

Generic topics of its interest are social hurdles on data sharing, education and training challenges, data management plans and certification of data repositories, disciplinary and interdisciplinary interoperability, as well as technological aspects.   The RDA is constituted of different elements, ...

The Way Farmers Learn

Acknowledging how farmers learn is a forced passage to the impact of knowledge generation and the way to link extension to research. This Janvry et al. (2016) paper presents an interesting perspective. It presents a few concepts such as “private learning” (learning-by-doing) by Bayesian updating. This consists of direct learning from own individual actions over time. There is also “social learning” (learning from others) with Bayesian updating and aggregation of observations collected from others according to a chosen pattern of weights.  

Thirty-nine Hints for FAIR Data in Agriculture and Nutrition

All data scientists know the importance of good and unambiguous definitions of data dimensions, crucial to all phases of data analysis. However, semantics is often left implicit in the data, the semantic resources used to create the data are not easily accessible, or available in non-standard formats, non (easily) machine-readable – all factors hampering the possibility of reusing data in information systems or integrating it with other datasets and ultimately limiting the interoperability of data. This paper presents recommendations to engage agrifood sciences in a necessary transition to leverage data production, sharing and reuse and the adoption of the « ...

The series of webinars will present the findings of five evidence reviews commissioned under the Research, Development and Deployment (RD&D) strand of the Sustainable Agriculture component of the COP26 Nature Campaign. The second webinar in the series focuses on agroecology and climate change adaptation and mitigation. Agroecology is increasingly promoted as a means to transform food systems globally, yet the evidence for generating large-scale impacts on climate change adaptation and mitigation in developing countries has been ...

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)]
