2.1 Descrição curta da tecnologia

Definição da tecnologia:

Utilization of continuous bench terrace (3 meters based) as sustainable soil and water conservation measure for tea plantation in slopping area of the northern Thailand

2.2 Descrição detalhada da tecnologia

Descrição:

The continuous bench terrace (forward-sloping terrace) as soil and water conservation measure in the high landscape at Angkhang Royal Agricultural Station, Moo 5, Mae Ngon subdistrict, Fang district, Chiang Mai province was constructed in 1999 in the area of former winter fruit plantation plot of the station. Land Development Department had surveyed, designed and constructed the 3 meters wide of continuous bench terrace, which it is suitable for the tea cultivation and total area is approximately 100 rai. The Angkhang Royal Agricultural Station had selected 50 households of Palaung hill tribe who have more ability and aptitude to grow Chinese tea to participate in the Chinese tea development and promotion project in 2000 and named this area as "Plot 2000". The overview of this area is complex mountainous terrain with slope range 16-30 percent, and average attitude is 1,400 meters above sea level. The soil texture is silty loam and very deep (more tan 1.2 meter), almost well drained soil. The soil organic matter is moderate around 1-3 percent. Moreover, the data of Doi Ang Khang Meteorological Station (Station Code 48302) is located at average attitude 1,529 meters above the sea level, and average temperature throughout the year is 22.9 Celsius with the highest temperature is 32.1 Celsius (during May) and the lowest temperature is 3.9 Celsius (during December), and average annual rainfall is 1,925.3 mm, with rain starting from April to October.
In the past, the watershed areas in northern Thailand have been disturbed by natural disasters, climate change, and human threats. The hill tribe people had invaded the forest to grow opium and shifting cultivation continuously. These condition caused the serious problem in soil erosion, runoff with soil surface, lose of topsoil and plant nutrients, decreasing in soil fertility and productivity with the extremely damage to upstream forest ecosystem. Until in the year 1969, Angkhang Royal Agricultural Station was established from the initiative of His Majesty King Rama 9, which aimed to conduct research on the planting of winter economic crops as an example for hill tribe to plant those crops as their career instead of opium cultivation, and also stop cutting and shifting cultivation. Nowadays there are more than 50 species of economic plants in this project and generating more income for land users, more than that this slopping area is the sustainable in land use and land management under organization of the Royal Project Foundation.
The benefits this technology is important in sustainable utilization of land resources in this area, and all land users around the Angkhang Royal Agricultural Station have stable and more income because they can grow Chinese tea and also other winter economic crops on this highland throughout the year. Moreover, this continuous bench terrace is more convenient for land users in fertilizer application, soil improvement, machines operation, tea harvesting and also yield transportation from cultivated plots to local processing factory.
The impact of implementation continuous bench terrace with 3 meters based:
1. The obvious economic and social impacts of land users are the stability of income from the production of Chinese tea, which are produced throughout the year. This conservation is more convenient for land users to implement in their plot and also transport from cultivated plots to local processing factory. The local officers from Angkhang Royal Agricultural Station and others government agencies closely advised and guided breeding, planting, soil management, harvesting and price guarantee.
2. The environmental and ecological impact is to reduce the amount of runoff and soil sediment, increase soil moisture, preserve soil nutrients and fertility, encourage biodiversity in the area of Plot 2000.
3. The society and culture impact is all ethnic groups are given the opportunity to receive the allocation of arable land according to the group of plants that they are comfortable and want to produce. Thus respecting the use of land in zoning as allocated from the station, including right to use water. These caused the strength of community institutions, where they have various crop production groups, organic fertilizer production Group and others. They are all member of the cooperative of the community.
