2.1 Short description of the Technology

Definition of the Technology:

Contour farming is a technology practiced in sloping areas in which hedgerows are established along the contours and other annual/cash crops are grown in the alleys between the hedges.

2.2 Detailed description of the Technology

Description:

Contour farming is being practiced by the farmers in sloping areas to prevent or control soil erosion. Hedgerows are established along contour lines using napier grass and permanent crops like banana and coconut. In between contour lines, corn is inter-cropped with peanut. It is a traditional practice of farmers and one of the conservation techniques for the Conservation Farming Village Approach (CFV).

Purpose of the Technology: This is practiced by farmers to control surface run-off, erosion and to conserve natural soil fertility. Napier grass is also planted as source of feeds for the livestocks. The technology controls dispersed runoff, reduce slope angle and length.

Establishment / maintenance activities and inputs: Contour lines were established using an A-frame to determine the location of the hedgerows to be planted. Napier grasses are planted along the contour at 8x8m and 4X4m distance. Grafted cacao trees are also inserted in between banana at 4X4 distance. The alleys between hedges measuring 4m wide and 30m long are planted with corn and peanut. Napier grass is regularly trimmed to maintain a height of not more than a meter, using the cuttings as livestock fodder.

Natural / human environment: The area is under a humid cilmate condition with an average annual rainfall of 1000-1500 mm per year. Its elevation is 500-1000 m above mean sea level.The average cropland size of land users is less than or equal to 0. 5 hectare with a slope ranging from 18-25%. Income of land users are derived from the crops sold.The Local Government Unit (LGU) provides truck to transport the harvested crops of the farmers from the village to the town market twice a week.

Strengths/ advantages/ opportunities in the land user’s view
Availability of labor force in the community. How can they be sustained / enhanced? Encourage more farmers to adopt the technology and utilize available labor force.
The technology generated jobs and increase the income of the landusers practicing the technology. How can they be sustained / enhanced? To conduct continuous capacity building to land users and their children to ensure sustainability.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Soil erosion was reduced because of the presence of the hedge rows that traps eroded soil. How can they be sustained / enhanced? Include other structural measures such as silt traps and brush dams to trap silts.
The kind of hedgerows planted depends on the need of the landusers. Farmers with livestock used napier and forage grasses as hedges while others planted perennial and cash crop to supplement their food requirement. How can they be sustained / enhanced? Conduct crop suitability evaluation and market study.
