Farm-centric research generally involves On-Farm Experimentation and may be better described as 'Farm Action Research', i.e. research conducted at least in part by and for beneficiaries who also farm. 

YEN

The Yield Enhancement Network (YEN) was launched in 2012 to support and energise on-farm learning-by-sharing and thus to enhance farming progress.

The Farmer-Led Innovation Network (FLIN) are UK based organisations driving farmer-led innovation - working together to power up and increase the impact of farmer led innovation initiatives.

At this years Agri-Tech E REAP Conference, Sarah Kendall, ADAS Crop Physiologist joined a panel consisting of Matthew Smith (Scientific Technologies) and Macelo Galdos (Rothamsted Research) to discuss how the digital world is informing and guiding the developments and decisions in the real world – ranging from digital twins to predictive models, from platforms to help with scenario planning to the use of AI and machine learning to yield unprecedented insights into the future of agriculture and horticulture.

Farmers, advisors and researchers working together to understand and improve crop nutrition on-farm

Agronomics is the science of understanding the variation in the cropped environment, identifying the management practices and system designs that work. It uses a farm centric approach of shared farm data and on-farm experimentation.

The ideas behind Farm-PEP came together in ~2018, drawing from the developments of Agronomics, the YENs, AHDB's Monitor Farm programme and the idea of a 'What Works' Centre for Agriculture. 

Inferring the right conclusions from field trials is important - how confident can you be that a result is 'real' rather than due to the underlying noise? As part of the Farm-PEP FIP project we are working with BGS to explore the best ways to communicate confidence, uncertainty, significance, probability and value with farmers and growers.

Precision farming involves the use of GPS, sensing and control technologies to use spatial data to manage soils, crops and livestock. 

ADAS have produced a new guide with our five top tips for successful on-farm trials. We'd love you to give it a try and to hear about what products or approaches you're testing on farm - by sharing the results of trials, we can learn more together.

Our PulsePEP trial will evaluate the novel method of bi-cropping spring peas, spring oats and spring beans in a rotation, looking at the impact on available nitrogen (N) in the following crop.  It will also evaluate the environmental benefits of including pulses in a rotation, by measuring greenhouse gas emissions, particularly nitrous oxide (N2O), over the course of the experiment. 

Understanding what works on farm through Explanations, Evidence, Experimentation and Exchange.  We are developing a community that supports knowledge generation and sharing of 'what works' on-farm, bringing together people, tools and resources - Do you want to be part of it?  For any one looking to test agronomic solutions for the ADOPT program we can support projects as facilitators, contractors or project partners.

Many of the most telling innovations that make a difference on-farm come from farmers themselves, or from close collaboration between farmers, advisors, industry and researchers

The INNO-VEG project aims to increase the speed and uptake of innovation in the field vegetable and potato sectors by: Defining and implementing a new approach for delivering cost-effective research. Establishing a cross border innovation network which will create the framework conditions for innovation to facilitate uptake of the new approach.

Direct Driller is a new farming magazine, designed by farmers for farmers to educate and inform the industry about direct drilling and no-till techniques, soil regeneration and soil conservation in arable and mixed farming situations. Direct Driller Magazine is available free to all farmers and agronomists who register with us and can be received in the post or via email depending on your preference. The key aim of Direct Driller is to help farmers to take back control of their farms and businesses and find a way of growing healthy crops using minimal effort and the correct inputs. It will be content put on by farmers, for farmers. We will showcase all the latest machinery and techniques, but the core of the Magazine is all about the soil and how you can use machinery, inputs and biology to improve it.

An online global conference on On-Farm Experimentation was held in 2023 - The proceedings are now published - 23 peer-reviewed papers and 34 short videos.

Farmer Innovation Group as part of the YEN Yield Testing EIP Agri project Amino acids have been widely reported in the farming press and in a few scientific papers to be biostimulants, but with little or no independent evidence from UK field conditions. This Amino Acid FIG was established to put that right, making eight tests in 2018 and five more in 2019.

Scientific Paper by Rob Bramley, Simon Cook and colleagues in 'Agronomy for Sustainable Development' 2022.

Farmer Innovation Group from the YEN as part of the YEN Yield Testing Project. The idea of crop momentum arose because high yields in the YEN associated with little-and-often applications, or ‘attention to detail’. Also, two interacting factors are thought to drive crop growth: assimilate supply (source), and assimilate storage capacity (sink). It was suggested that the initial source may affect the sink at the next stage; so increasing initial growth may enhance subsequent growth, creating ‘momentum’.

Agroforestry is a long game — but research funding isn’t always. With trees taking years to mature, designing meaningful short-term agroforestry trials can be tricky. Defra’s ADOPT competition offers funding for projects up to 24 months, making it best suited to research that either focuses on early tree establishment or taps into existing, mature agroforestry systems.
