2.1 وصف مختصر للتقنية

تعريف التقنية:

Maize strip tillage is a technology used for corn cultivation. It cultivates only thoses stripes in which the seed is added to.

2.2 وصف تفصيلي للتقنية

الوصف:

Maize strip tillage is 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 prior seeding. 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. The work is done within one working unit compared to the traditional technique whereas the farmer needs to drive for each working step separately.
There are some clear ecological advantages using this technology. Like in a minimum tillage system the stability of the soil is enhanced.
Due to these mulch-stripes the matrix of the soil is more complex and therefore the stability is better especially during harvest in September. The interviewed farmer said compaction would occur less and the risk of soil erosion is decreasing. Especially in hilly areas the technology is suitable since soil erosion is a problems when using a plough. Another advantage is the better soil structure due to the mulch stripes and the minimal tillage ensures that the soil is more stable.
A high level of knowledge about the natural environment is a required when adopting this technology. On one hand, the farmer must time the date for seeding adequately to the natural conditions (not too humid). On the other hand, the farmer has to apply Glyphosphat one to three times after the seeding in order to guarantee an optimal growth period for the corn.The interviewed farmer found it problematic to use this amount of Glyphosat and he was not sure about the effects in the water. The timing to start seeding with this technology may be later cause corn is sensitive towards rival plants, low temperatures and humidity. When adopting the technology the farmer needs to have a certain level of knowledge and experience in order to guarantee a sound harvest.
This technology is applied in the village Seedorf (Canton Bern) after the farmers made positive experiences and if they see the economic advantages too. Generally there is only one work step needed for the seeding which lowers the costs compared to the traditional technology with about a third. Furthermore the subsidies of the canton of Berne enables farmers to apply this technology for the first 5 years. In this cycle the areas are usually left with grass first, second cultivated with corn (using maize strip tillage), then sugar beets and after all two years of cereals (wheat and rye) before the cycle starts again.

6.7 نقاط القوة / المزايا / الفرص التي توفرها التقنية

نقاط القوة/ المزايا/ الفرص من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات
Prevention of erosion How can they be sustained / enhanced? Maintain green cover.
Improvement of soil quality (fertility, organic matter, moisture retention, soil structure) How can they be sustained / enhanced? Ensure that cover vegetation doesn’t compete with the vines; improve soil properties by applying mentioned agronomic measures.
Contribution to a better balanced and more stable ecosystem (with living space for a wider range of organisms) How can they be sustained / enhanced? Specific management of cover crops (alternating treatment of inter-rows; find solutions to replace application of herbicide).
In the long-term economically beneficial because of cutting costs of restoration of soils and fertility loss after heavy erosion events.
Possibilities of farm income increase through marketing wine under the ‘vinatura’ label, certifying ecologically produced wine.
