Comments:

contour ploughing conserves soil from land degradation by erosion.

2.1 Short description of the Technology

Definition of the Technology:

Contour farming is a practice of ploughing and/or planting across a slope following its elevation contour lines. The contour lines create a water break which reduces rill and gully forms of soil erosion in case of heavy storms. The water break allows more time for more water to percolate/sink into the soil, thus reducing the amount of water left to run off the surface.

2.2 Detailed description of the Technology

Description:

Improved Maize variety (Longe 10) is popularly grown in Northern Uganda due to its high yielding ability. Northern Uganda has a generally flat landscape although along the river banks it is slopy with high risk of soil erosion. This has motivated the land user to grow his maize along the slope using contour ploughing which is a sustainable land management practice. Contour farming is a practice of ploughing and/or planting across a slope following its elevation contour lines. The contour lines create a water break which reduces rill and gully forms of soil erosion in case of heavy storms. The water break allows more time for more water to percolate/sink into the soil, thus reducing the amount of water left to run off the surface. Northern Uganda has a tropical savanna climate with one growing season. Rainfall is usually moderate ranging from 1000-1500 mm per annum and sometimes occurs with heavy storms. Rainfall is received from April to November with a dry spell in June and July which affects crop growth.
The maize was grown for commercial purposes in a 25 x 25 acres of land on contour lines with the aim of controlling soil erosion, and increase plant nutrients, soil moisture, productivity and household income. The maize is planted along the contour lines at a spacing of 30 cm between the maize plants and of 1 meter between the rows that runs across the contour field. Holes for planting maize are dug at a depth of 30 cm along the contours with four maize seeds planted per hole and covered with soil immediately since the contours creates a water break which reduces the formation of rills and gullies during heavy water run-off which is a major cause of soil erosion.
The activities involved in establishing such a technology include clearing the field during the dry season in March and second ploughing in early April to alter the soil and allow proper decomposition of the grass and also creating contours during planting in early April at the onset of the rainy season. Weeding is done twice, first two weeks after maize germination in late April, and lastly in June.
Inputs needed to establish the technology include ox-plough, hoes, and pangas used to clear the field. Inputs for maintaining the technology include hoes for weeding the maize crop and also checking that the contours are not destroyed by the run-off.
The technology is liked because it is good at controlling soil erosion on the gently sloping field, increases plant nutrients and soil moisture, and increases productivity. But it is disadvantageous when contours collapse which is accelerating the speed of surface run-off.
