2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

An agroforestry system where legumes and cereals are planted in fruit orchards, giving simultaneous production and conservation benefits.

2.2 Descripción detallada de la Tecnología

Descripción:

In the Faizabad region, Tajikistan, an area which is characterised by hilly topography, and deep but highly erodible loess soils, farmers traditionally cultivate beans and wheat in combination with fruit trees. This was a rather unsystematic agroforestry system, and during Soviet times (in the 1980s) fruit production was intensified. Pure-stand orchards were established: the land was levelled and on slopes exceeding 20%, terraces were constructed mechanically. The density of trees was increased, and the little space remaining between was used for hay production. Annual cropping was stopped.

Purpose of the Technology: After the Soviet era, farmers reduced the number of trees, allowing room for inter-cropping. They also established new orchards according to this same pattern. Those who farm rented land merely inter crop wheat, whereas the few farmers who own their land, rotate crops with two years of wheat, followed by one of legumes (beans or lucern). Crops are grown both for home consumption and sale.

Establishment / maintenance activities and inputs: The density of apples was reduced by expanding the spacing from approx 5 m to 10 m between rows, and from 2 m to 4 m within rows. Along each row of trees a 2-3 m strip of grass was left to grow. The layout of fruit trees in lines is a compromise between being along the contour, and against the prevailing wind. After harvesting of the fruit, between August and October, farmers sow their annual crops.

Natural / human environment: This agroforestry system provides protection against strong winds, heavy rains and flooding. Soil erosion (by water) has been reduced due to improved soil cover by the inter cropping, and through leaf litter, which is left to decompose on the ground. Furthermore, after harvesting, about three quarters of the crop residues are left on the field as mulch. The remainder is used as fodder. Soil organic matter within the current agroforestry system is considerably higher than in the surrounding grazing areas. Soil fertility has improved also: beans can fix 60-80 kg/ha/year of nitrogen. Compared with other crops, wheat provides the best erosion protection. Since the lateral rooting system of the apple trees reaches only 1-1.5 m from the trunk, competition for nutrients is not a major problem. Neither is there a problem with shade, since during the crop establishment period the trees have lose their leaves. In order to increase production, farmers plan to apply supplementary irrigation where possible.

• reducir, prevenir, restaurar la degradación del suelo

3.2 Tipo(s) actuales de uso de la tierra donde se aplica la Tecnología

Comentarios:

Major land use problems (compiler’s opinion): Most of the rains fall in late autumn and early spring, and the rains coincide with very strong winds. The topsoil is therefore exposed to erosion during this period if left uncovered, and without a windbreak. A particular problem during the soviet period was that the intensive orchard system meant annual food crops were left out of the production system: soil cover was reduced and there was less food.

Type of cropping system and major crops comments: two years of wheat followed by one of legumes (beans or lucerne)

Comentarios:

Cost calculation refers to farmers who established new agroforestry plots (without receiving any incentives). These are farmers who have rented land from state farms. However, conversion of Soviet orchards is more common than the establishment of new agroforestry plots (information on costs not available).

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
Easy to convert orchards How can they be sustained / enhanced? Land reform from state to private ownership would assist the process and strengthen farmers' associations.
Helps provide employment (mainly self- employment, partial employment of additional labourers) and increased self-sufficiency. With the cultivation of wheat, some farmers can solve their food problems and do not need an off-farm income.
Improvement of soil fertility and soil organic matter content How can they be sustained / enhanced? Use all the crop residue and leaves of trees as cover (mulch).
Considerable reduction of soil erosion How can they be sustained / enhanced? Adopt cover crop and rotate with other legumes and minimum tillage system.
Wider spacing between the rows of trees (to 10 m) is best for the agroforestry How can they be sustained / enhanced? Remaining orchards with the original Soviet spacing of 5m between the rows should be thinned.

6.8 Debilidades/ desventajas/ riesgos de la Tecnología y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
The irrigation system established during Soviet times required high maintenance inputs due to siltation of the canals. During the period of the civil war systems ceased to function, the canals filled up with sediments and finally overflowed during rain storms causing gully formation	Control of water flow within the orchard using cutoff drains and drainage ditches.
Lines of trees which are planted up and down the slope to provide wind.	Compromise in layout design (see description).
Orchards managed by state farms are often not well looked after.	Leasing of land and awarding landholder certificates leads to improved orchard management.
