2.1 Courte description de la Technologie

Définition de la Technologie:

A combination of fruit- and nut-trees together with seminatural trees and shrubs on one side with grass-communities on the other side provide for a diversified production system.

2.2 Description détaillée de la Technologie

Description:

Fruit- and nut-trees give the production system the characteristics of an orchard, whereas sour cherry trees rather provide for a jungle atmosphere. They spread very quickly once they are planted. Hayproduction substitutes other uses of the lowest vegetation layer, since grazing is forbidden. The whole territory is concipied as a research station.

Purpose of the Technology: In general trees act against erosion: By their stabilising function they prevent soil from being washed out. Especially nut-trees with their 20 to 25 m long roots preserve soil moisture and by that consolidate soil structure. Terraces contribute to this moisture-preserving and production-enhancing function. They are very important in order to make rather steep land exploitable by reducing slope. Haymaking does not damage soils, but is only allowed after the end of June so that grasses can reproduce before.

Establishment / maintenance activities and inputs: Both the establishment of terraces and the planting of trees on such a big surface are costly in terms of labour and money. Maintenance means taking care of trees, taking measures against diseases and conserving soil fertility. Fertilisers are very costly and therefore dung has been substituting them in the last years.

Natural / human environment: From the two research stations of the orchard institute - one in the upper hill-zone and one close to the village Karsang - only the second one is assessed. This area is surrounded by two rivers in the West and in the East, with its main exposition to the South. It is in direct competition for irrigation water, especially needed for the trees, with the village. The orchard is situated on a ridge that is in the haymaking area, but is accessible for animals from the village.

Commentaires:

No damages by heavy rainfall in the orchard, whereas next to it there is damage. Especially winds cause damages by covering vegetation with dust and impeding them from making fotothynthesis. Plants can die therefore.
