Location: Addis Ababa, Ethiopia Duration: 24-27 August, 2015 Purpose of meeting: Adapt the OFRA FOT prototype tool to 9 Ethiopia Agro-ecological zones based on Ethiopia Legacy and OFRA 2014 trial data. Participants will be trained on changing default response function coefficients with their AEZ specific empirically generated coefficients based on field research. OFRA team members involved: […]

Location: Addis Ababa, Ethiopia Duration: 18-21 August, 2015 Purpose of meeting: To support OFRA PIs in future FOT development needs to adapt them to local conditions and ISFM practices on a demand or need basis. The participants will be trained on how to update the current FOT prototype tool developed using Uganda data. OFRA team […]

Progress report: AGRA Grant Narrative Progress Report (Jul-Dec’14) Book: Fertilizer Use Optimization in Sub-Saharan Africa This 228 page book provides a detailed explanation on optimizing fertilizer use within an Integrated Soil Fertility Management Framework in 13 African countries. Journal paper:  Fertilizer use optimization approach: An innovation to increase agricultural profitability for African farmers H. Rware (1), C. Kayuki […]

Linking Model Use with Spatial Information for Improved Extrapolation of Soil Management Information: Visiting scientist opportunities The project Optimizing Fertilizer Recommendations in Africa (OFRA) is developing the capacity for much enhanced farmer profitability resulting from fertilizer use. Decisions are made in consideration of financial, environmental, and cropping system aspects of the individual farmer’s context. OFRA is […]

One of the key outcomes of the OFRA process is to improve the use of research data to support fertilizer use guidelines. The existing data on fertilizer responses has been supplemented with new data from on-station and on-farm nutrient-response trials using standard protocols and data entry protocols – both can be downloaded for reference. The […]

OFRA research is generating fertilizer response curves and reviewing findings from previous research. This data is mapping out the relationship between the application of nutrients and the crops produced. One of the key outputs of this work is the development of over 60 Fertilizer Optimisation Tools. This approach differs from much of the previous work because […]

The development of customized, country specific fertilizer optimisation tools moved a step closer last week as a result of the OFRA workshop in Arusha, Tanzania. The workshop brought together experts from Kenya, Uganda, Rwanda and Tanzania specially to look at how tools could be developed that share information across similar agro-ecological zones. Harrison Rware, the […]

9-12 February 2015 saw the delivery of an OFRA development fertilizer decision tool workshop in Arusha, Tanzania, bringing together participants from Tanzania, Kenya, Rwanda and Uganda. Scientists from these countries will explore the potential of the fertilizer optimization tool (FOT) being developed in OFRA, and work on important issues to address the needs of the […]

Scientists from Tanzania, Kenya, Rwanda and Uganda will explore the potential of the fertilizer optimization tool (FOT) being developed in OFRA, and work on important issues to address the needs of the different agro-ecological zones in the region. They will also be exploring adjustments that need to be made to the decision tool as a result […]

Optimising Fertilizer Recommendations in Africa (OFRA) was a project led by CABI which ran from July 2013 to July 2017 The project was a partnership between CABI, the University of Nebraska Lincoln and National  and agricultural research and extension systems in 13 countries in sub-Saharan Africa. OFRA was supported by the Alliance for a Green Revolution […]
