The system is a unique indigenous cultivation technique used in all Matengo highlands to conserve soil moisture and minimize soil erosion. It is a grass fallow tide ridge system characterised by crop rotation and maintenance of soil fertility by compositing grass, weeds and crop residues. It is an intensive system of cultivation on steep mountain slopes. The system has sustained land productivity for at least 200 years in Mbinga District.|

Mbinga District is composed of mountains, valleys and plateaus that extends from 800 - 1900m above mean sea level. The District is divided into four major agroecological zones representing combinations of unique altitude ranges that have variable characteristics.|
Mbinga District is characterised with Haplic or Humic acrisols depending on their position in the topo sequence. At higher elevations the most common soils are highily leached yellow red soils which are well drained with good permiability. At lower elevations, soils are less leached brown red in colour sandy clay loams and sandy clays.|
Mbinga District is characterised by tropical temperate with a unimodal rainfall pattern. The rain season extends for at least six month from November through May with a colder dry season for the remainder of the year. Average minimum and maximum temperatures are 19 - 23 degree celcius and 29 - 31 degree celcius respectively. Average annual rainfall for the District is 1224mm.

Almost all income is derived from agriculture, coffee being the main cash source. At lower altitudes maize and beans are the main cash crops. Another sources of income is pig  and poultry keeping. |
The average income level for Mbinga District is Tshs 219,238,000 per year. Income per capital is 489,639 Tshs per year (According to 2006 household survey data)|
In Mbinga District the dominant land tenure system is customary land ownership with much of the land being un surveyed. Due to the nature of land tenure systems families have equal rights to use land although head of families have decisive rights.

This Indiginious conservation technology ''Ngoro'' is considered best due to its efficiency in controlling soil erosion, increasing soil moisture at critical times of the year and maintaing soil fertility, consequently increasing both production and productivity. |

4. To improve soil structure.

ការព័ណ៌នាសង្ខេបនៃសកម្មភាពសំខាន់ៗ ទៅតាមទិសដៅរបស់វា

Increased productivity is attained as a result of high soil fertility, water availability and better soil structure.|
Water retention capacity is improved through organic matter and micro pits which act as water micro catchment.
Soil fertility is improved by compositing grass, weeds and crop residues and also by crop rotation and planting of legumes. |
Soil structure is improved through addition of organic matter.

The Ngoro system is based on rows and pits that form a grid pattern. Usually men cut the grass and lay it in rows forming a grid and women do the cultivation. The rows which are 2m or 3m apart roughly follow contour lines, with distance between them depending on the amount of grass to be covered and the soil depth with which to cover it. The soil in the  squares is dug out and pulled on top of rows of grass. In this way one quarter of the work is done facing downhill and dragging the soil. Digging continues until the subsoil is exposed in each ngoro pit. The depth of the pits normally ranges between 10cm to 50cm. The crop is planted on the raised beds surrounding the ngoro pits. Maize is normally planted in one field as a pure crop and beans and peas are planted as pure crops on the other. The plant beds are clean weeded with the weeds being pulled out and thrown into the pits to form compost. After harvest crop residues are also thrown into the ngoro pits, the old soil beds are split and new beds formed over old pits. The new ngoro pits come to occupy the places where the former soil beds intersected. The rotation is strict, a grain crop, usually maize, alternating with a leguminous crop, normally beans and peas.|
