Through experience with herbicide application the land user learned that there are possibilities to minimize the amount of herbicide application to fields.
The land user interviewed has an experience of nearly 30 years with the application of herbicide to his fields. Through this time he learned that there are ways to reduce the amount of herbicide and thereby conserve soil and nature against this aggressive pesticide. There are different factors to consider to reduce the herbicide application such as time of the day to bring out herbicides or time of the year. For example there is less herbicide needed the earlier in the morning it is applied to the field.
Purpose of the Technology: There are two main purposes of the technology. The fist is to protect crops and to not damage them with great amounts of herbicides. Thereby, also environment as a whole and especially waters are protected because there is always a part of herbicides washed out of soils and into waters. The second aim is more economically. As the effectiveness of the application of herbicides is worse in spring than in autumn, it should be prohibited by law to use herbicides in spring. On the other hand, land users should be allowed to use herbicides for a longer time in autumn because crops tend towards dormancy. Thereby, not only the amount of herbicides applied to a field can be reduced but the land user is also saving money.
Establishment / maintenance activities and inputs: The establishment and maintenance of the technology requires first of all a great deal of knowledge. To receive the desired target situation there are many points to be discussed of the current situation with herbicide application. One point is the free pass which enables land users with a basic education to practice pest management even if they do not know what a pest management gun is and how it is used. A solution to this problem of lack of knowledge is seen by the land user through the structural change in agriculture. Companies providing spraying services are more efficient and tidy than the land user can be.
Natural / human environment: The technology helps protecting the environment and waters from pollution through washed out herbicides. This must always be kept in mind when discussing about the amount of herbicides. Some land users do not trust a smaller amount of herbicides to be as effective as the standardized one. But this overthinking must now be made because it is until today not sure what side effects herbicides have to the human and natural environment.

Society required an overthinking of traditional pest management techniques over the last years. The land user started individually with his tests. But also in politics there were some attempts to reduce herbicides in agriculture. Third, the farmer's association works together with the local government of Bern on solutions for reducing herbicides which could be applied nationwide.

Major land use problems (compiler’s opinion): The major land use problems are erosion by water through heavy rainfall events and therefore loss of soil. Regarding the technology there is also the problem of the extensive use of herbicides and its inappropriate application. This can lead to damages to the following crop, chemical resistance and pollution of waters.
Major land use problems (land users’ perception): The area is likely to be affected by erosion as the main problem. Therefore, cultivation must be adapted to prevent soil erosion by water. The land user is also convinced of a pollution of waters through different human-induced reasons such as the inappropriate and ineffective use of herbicides.
Main measures: agronomic measures
Type of agronomic measures: retaining more vegetation cover, mulching, mineral (inorganic) fertilizers, zero tillage / no-till, minimum tillage
Main type of degradation addressed: Cp: soil pollution, Hp: decline of surface water quality
Secondary types of degradation addressed: Wt: loss of topsoil / surface erosion
Main causes of degradation: soil management (Use of herbicides in the past that are forbidden today have polluted soil and the environment substantially.), discharges (point contamination of water) (discharges of herbicides from agricultural fields into water bodies)
Secondary causes of degradation: Heavy / extreme rainfall (intensity/amounts) (not a main cause because the busy season of pesticides is in spring and heavy rainfalls mainly occur in autumn)
Main goals: prevention of land degradation
Technical knowledge required for field staff / advisors: high (Vital role of agricultural advisor, who must be neutral and not a salesman.)
Technical knowledge required for land users: high (The land user always needs to have the best knowledge which must also be up to date. Therefore, he depends on a competent agricultural advisor. The knowledge he gained is transferred to his employees.)

Costs are calculated for a land user applying herbicides on his fields of a size of total 5-15 ha. Maintenance costs are calculated for one year, establishment costs for the implementation of the technology.
The area size of the agricultural fields is the most determinate factor affecting the costs. The smaller the application area of herbicides is the higher the costs get. To cut costs a land user needs to have a bigger area to apply herbicides on.

Because of increased crop yield
Improved livelihoods and human well-being
The fact that the consequences of herbicides e.g. glyphosate for human health are not yet known disturbs the public. Also land users do not agree on the benefit or damage to natural environment because of herbicides. Therefore, minimizing the amount of herbicides applied as much as possible is an important step. An overthinking of the current situation but also much more knowledge and research on this topic must be provided in order to improve livelihoods and human well-being even more.

Biodiversity / crop diversity
The technology to minimize the amount of herbicides applied to agricultural fields must be understood as a sort of overthinking effect which does not consist of precautionary methods. Therefore this question can not be answered.
If agriculture wants to do fully without application of herbicides, changes in the payment and costs of labour must be lowered significantly. As labour is more and more replaced by machines, human labour is still too high when it comes to the costs.
75% of land user families have adopted the Technology with external material support
Comments on acceptance with external material support: 75% of land user families in the region of Bern applied the SLM Technology because they saw the positive economical effect that minimization of herbicides gave them.
There is a strong trend towards spontaneous adoption of the Technology
Comments on adoption trend: There is also a trend against the adoption of the technology: current young land users need a too low profile of qualification for economical subsidies. This can lead to "bad land users" in the future. The profile of qualification should be lifted up for getting subsidies and thereby the appropriate use of subsidies would be learned.
The application of herbicide ensures the crop production against alien crops. Therefore, to ensure this production the right application of herbicide is needed. Minimal amounts can lead to exact the same output of production.
How can they be sustained / enhanced? To ensure the crop production or even increase it through elimination of alien crops the right application of herbicide is needed.
Once the land user has the knowledge he needs to minimize the amount of herbicide it is simple to apply the technology on agricultural fields. Using this knowledge not only safes time for the land user but also money. There can be saved up to 50.-$/ha for herbicide.
How can they be sustained / enhanced? The spreading of knowledge on amounts of herbicide and the right application is highly important for the success of the technology. This must be guaranteed by government, local institutions or agricultural advisors and research.
The minimization of herbicides is important because it provides a solution to the last main problem in conservation agriculture, especially no-tillage. If there is no or less skepticism against the application of glyphosate or other herbicides the implementation of no-tillage in agriculture could be enhanced even more.
How can they be sustained / enhanced? It is important to minimize amounts of herbicides even further and to look for probable alternatives to these pesticides. This would lead to a far more sustainable land management in Swiss agriculture and to more land users adopting no-tillage.
|The acceptance of the system of herbicides is one great problem of the technology. Even after reducing the amounts of herbicides, there will be critical voices on the application of herbicides.||Acceptance in public should be received for this technology. However, the technology itself provides no solution to this problem.|
|The aim of reducing the application of herbicides is formulated quickly. However, the transfer of knowledge needed and its application into the daily program of a land user is very difficult. Furthermore, the knowledge provided by agricultural schools is not yet up to date.||The knowledge provided for land users, agricultural advisors and even students and teachers must be up to date in order to provide the latest results from research and to help implementing the technology of reducing herbicides even further among swiss land users.|
