2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Organic agriculture is a system of crop cultivation that uses biological methods of pest control and organic fertilizer as substitutes for chemical fertilizers and pesticides. It targets sustainability, enhancement of soil fertility, and biological diversity by aiming to close nutrient cycles while generally prohibiting synthetic pesticides, antibiotics, synthetic fertilizers, genetically modified organisms, and growth hormones.
2.2 Detailed description of the Technology
Description:
Organic agriculture is a globally applied technology practiced on agricultural land. It is carried out in 188 countries, with over 96 million hectares of agricultural land managed organically by at least 4.5 million farmers.
The main elements of this technology include the use of biological methods of pest control and organic fertilizer application, which replace chemical fertilizers and pesticides. It generally prohibits synthetic pesticides, antibiotics, synthetic fertilizers, genetically modified organisms, and growth hormones. The purpose of organic agriculture is to achieve sustainability in farming, enhancing soil fertility, increasing biological diversity and reducing the reliance on external inputs to agriculture, relying on nutrient recycling by applying manure and on biological nitrogen fixation from legumes. It also aims to provide a healthier and more environmentally friendly alternative to conventional farming practices. To establish and maintain organic agriculture, major activities include the application of organic fertilizers, crop rotation, and the use of pest-resistant plant varieties. Regular soil testing and monitoring of pest populations are also necessary. Certification of a farm as being officially organic is needed if the products are to be sold at a price premium.
Organic agriculture can improve soil health, reduce pollution of the surrounding environment, and contribute to biodiversity in the fields. Moreover, it can offer healthier food options and potentially higher income for farmers due to the premium prices of organic products. Land users appreciate organic agriculture for its environmental benefits and potential for higher income. However, some dislike the increased labour and time required, the 10-30% of reduction in yields, compared to conventional agriculture, as well as the need for a transition period before farms can be certified as organic and products sold at a premium price.
The DOK experiment presented here is representative of organic practices in the context of temperate regions (specifically, Switzerland and surrounding countries). It is jointly managed by the Research Institute of Organic Agriculture (FiBL), and by the Swiss Confederation's centre of excellence for agricultural research (Agroscope). The name "DOK Experiment" is derived from its main purpose, to compare three cultivation systems: Biodynamic (D), organic (O) and conventional (K) agriculture. These differ in terms of how they are fertilized (D: liquid manure, manure compost, biodynamic preparations; O: liquid manure, rotted manure; K: two variants, one with liquid manure, fresh or rotted manure, mineral fertilizer (CONFYM variant) and one with only mineral fertilizer (CONMIN variant)), as well as by plant protection (D and O: organic; K: chemical-synthetic). In addition to two fertilization levels of the three cultivation systems (half fertilization and standard practice fertilization), two controls are carried out, an unfertilized (N) and a purely mineral-fertilized variant (M). The experiment is spatially replicated four times. The results presented here refer to the conventional (K) and the organic (O) treatments at the standard practice fertilization level.

4.3 Establishment activities
Activity | Timing (season) | |
---|---|---|
1. | Courses on the principles of organic farming | Before transition |
2. | Transitioning period (already practicing but not yet certified) | 2 years |
3. | Certification | Start of year 3 |
Comments:
Detailed information on the transition process and requirements can be found here:
https://www.fibl.org/de/shop/1001-umstellung
4.4 Costs and inputs needed for establishment
Comments:
Courses are needed when transitioning to organic agriculture. They usually take around a week and the cost of courses depends locally.
Further, there are costs for certification, which are usually 400 CHF.
The main costs of transitioning is lost yields in the years during transition, when there is no price premium, yet. Subsidies depend on the Swiss Canton.
Some detailed information on the cost associated with transition can be found here:
https://www.bioaktuell.ch/grundlagen/umstellung/allgemein/kosten-und-beitraege
4.5 Maintenance/ recurrent activities
Activity | Timing/ frequency | |
---|---|---|
1. | Application of manure | At least yearly |
2. | Application of slurry | Usually twice a year |
3. | Soil preparation by harrow or cultivator | Yearly |
4. | Weed supression by tine weeder | At least yearly |
5. | Biological pesticide application (e.g., Novodor) | When needed, mostly in potato |
6. | Planting of cover crop | After wheat |
7. | Mulching cover crop | Before planting soy/maize |
Comments:
The measures here reflect the activities that are in addition to conventional management needs. Their exact sequence depends on selected crop rotation. In the DOK experiment is was silage maize, soybean, winter wheat, potato, winter wheat, and two years of grass-clover.
4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)
Specify input | Unit | Quantity | Costs per Unit | Total costs per input | % of costs borne by land users | |
---|---|---|---|---|---|---|
Labour | Labour requirements compared to conventional agriculture | % | 113.0 |
Comments:
Because this is a research trial, the detailed costs are neither available nor would they be representative of typical organic farms. Therefore, it is best to rely on the estimated costs from an international study. Based on this study there are 13% higher labour costs in organic farming, but the higher labor cost in organic systems is offset by lower costs of purchased inputs. The total production cost is not different to conventional farming. When the actual organic premiums are considered, gross returns, benefit/cost ratios, and net present values are significantly higher for organic crops compared to conventional crops (21%, 24%, and 35%, respectively).
The study is available here:
https://www.doi.org/10.1073/pnas.1423674112
A good way to estimate the costs of organic vs conventional production is the KTBL Performance Cost calulator. It can be specified to farm and machinery size, soil type and has an option for organic agriculture to see the differences. (only in German language):

Specify assessment of on-site impacts (measurements):
All presented results are from published studies about the DOK experiment.
6.2 Off-site impacts the Technology has shown
groundwater/ river pollution
Greenhouse gas emissions per land area
Comments/ specify:
Based on a recent modeling study, emissions were between 0.5 to 1 t CO2 equivalent less per ha and year in organic compared to conventional agriculture in Switzerland (https://doi.org/10.1016/j.agsy.2020.102822).
Greenhouse gas emissions per calorie
Comments/ specify:
In contrast to emissions per land area, it has been found that due to the lower yields there is little difference in terms of emissions per unit of food produced (https://doi.org/10.1088/1748-9326/aa6cd5).
Specify assessment of off-site impacts (measurements):
There are ongoing debates on whether organic agriculture really leads to lower emissions than conventional agriculture, and the conclusion largely depends on the unit of reference (amount of food vs. per ha).
6.3 Exposure and sensitivity of the Technology to gradual climate change and climate-related extremes/ disasters (as perceived by land users)
Gradual climate change
Gradual climate change
Season | increase or decrease | How does the Technology cope with it? | |
---|---|---|---|
annual temperature | increase | well | |
seasonal rainfall | summer | decrease | well |
Climate-related extremes (disasters)
Climatological disasters
How does the Technology cope with it? | |
---|---|
drought | moderately |
Comments:
Preliminary results from rain-emission shelters indicates similar resilience of the organic agriculture treatment as the conventional ones to drought.
However, organic agriculture in general is expected to better cope with climate change than conventional agriculture (https://www.fibl.org/fileadmin/documents/shop/1500-climate-change.pdf)
6.4 Cost-benefit analysis
How do the benefits compare with the establishment costs (from land users’ perspective)?
Short-term returns:
negative
Long-term returns:
positive
How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
Short-term returns:
slightly positive
Long-term returns:
slightly positive
Comments:
The main establishment costs is that in the first years of establishment, farmers have to apply all organic principles and thus have lower yields. However, certification as organic produce, which receive price premiums, is only possible 1-3 years after establishment, depending on the farm type. Thus, there is a period in which the lower yields are not yet compensated by a price premium. Once the system is certified and a price premium received, gross returns, benefit/cost ratios, and net present values are significantly higher for organic crops compared to conventional crops (https://www.doi.org/10.1073/pnas.1423674112)
6.5 Adoption of the Technology
- 11-50%
If available, quantify (no. of households and/ or area covered):
About 16% of all farms in Switzerland are currently organic. (BAFU; https://www.bfs.admin.ch/news/de/2024-0392)
Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
- 51-90%
Comments:
Switzerland has specific subsidies for those that practice organic farming but also many subsidies that all farmers receive. It is thus not 100% clear how many farmers were mainly incentivized by the additional subsidies. However, most become organic farmers out of conviction that it is the better and more sustainable farming system.
6.6 Adaptation
Has the Technology been modified recently to adapt to changing conditions?
Nee
