2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Maize strip tillage is used for corn cultivation and the technology ensures that only those stripes are cultivated where seed is applied.

2.2 Descripción detallada de la Tecnología

Descripción:

Maize strip tillageis a soil conservation method used in crop production. First of all the grass in the area needs to be prepared by splattering round-up some 3-10 days in advance. Then the actual maize strip tillage machine carves a stripe and the seed are inserted within this 30 cm strip. At the same time fertilizer is added on these cultivated stripes. Between those cultivated stripes the mulch-grass stripes (45cm) are unmechanised and protect the soil by increasing its stability. Due to these mulch-stripes the matrix of the soil is more complex and therefore the stability is better especially during the harvest in September. The interviewed farmer said it was cause of the improved soil structure that his tractors are not subside and compaction is also less likely to occur. Another advantage is the decreased risk of soil erosion when having more and heavy precipitation, as it is expected for next decades due to climate changes in Switzerland. Thanks to the SLM technology, water infiltration increases and organic matter as well which adds up to a promising growth period.
There are also clear economic advantages, by adopting the technology. In springtime only one working step is needed for seeding compared to the five steps needed with the traditional technique using a plough. Therefore the costs are finally lower with this technology and farmers can use the opportunity when having free labour to work part-time outside the farm. At first sight, the costs might seem higher when adopting this technology cause the farmer needs to hire a subtractor, in the end the costs are lower due to the lower labour input and the lower equipment costs. After having seen the advantages, the interviewed farmer said that the technology is usually maintained.
A high level of knowledge about the natural condition is needed when adopting this technology. On the one hand, the farmer must time the date for seeding adequately to the natural conditions, it needs some 4 days with no precipitation. Then on the other hand, the farmer has to apply Glyphosphat after the seeding in order to guarantee an optimal growth period for the corn. The timing to start seeding with this technology may be later cause corn is sensitive towards rival plants, low temperatures and humidity. These are some of the limits that the technology implies. If springtime is humid, the farmer should be allowed to use the traditional technique, regardless of the subsidies as indicated by the interviewed farmer. The canton of Bern is providing subsidies if the farmer commits to use a five year cycle which inherits not to use the plough during this period but using a mulch system. The interviewed farmer suggests that the canton of Bern could commit itself not only in giving subsidies to the areas but also to support if contractors like him would get subsidies for the investment for machines that are needed. For a single farmer the establishment costs for the equipment are too high so that the average is hiring a contractor who could work for a lower salary when having support to buy machines, so subsidies from the Cantons would be an asset.

4.6 Costos e insumos necesarios para actividades de mantenimiento/ recurrentes (por año)

Comentarios:

Establishment costs are estimated for the contractor on the one hand and labour costs indicated above are the ones that the contractor is demanding for if he is hired. Additionally, those farmers who adapt this technology can get subsidies from the Canton if he/she commits to apply soil conservating measurements during 5 years, in Bern it is 450 CHF per ha.

4.7 Factores más determinantes que afectan los costos:

Describa los factores más determinantes que afectan los costos:

Labour costs and costs for diesel are much higher for the traditional technology (plough). The investment for the technology are high in the first term and the labour costs indicated above are given by the contractor if he is hired. So for a regular farmer only these 388 USD are relevant.

5.6 Las características de los usuarios de la tierra que aplican la Tecnología

Indique otras características relevantes de los usuarios de las tierras:

Difference in the involvement of women and men: Generally speaking, men tend to work on the fields therefore are mainly responsible for technologies, women tend to work in the houshold and are responsible for administrative tasks. In Switzerland there is a traditional labour division between men and women, there might be exceptions but if addressing new technology one has to deal with male farmers. Assuming that decisions to adapt new technologies or for investments are made by both.

Population density: 10-50 persons/km2

Annual population growth: < 0.5%

Off-farm income specification: For those farmers working off-farm it is likely to delegate work to contractor. On the other hand when hiring a contractor there is less labour needed for the farmer and the possibility to work off-farm slightly higher.

Comentarios:

With the grass stripes between the corn rows, the water can infiltrate faster and the soil is more stable and protected. The technology can be more tolerant towards intensive rainfalls but only to a certain extent. The technology is more sensitive when having humid conditions in spring and problems can occure then when trying to apply the stripe mill cropping..
