Citrus orchard with grass and trenches for soil erosion control (Issa Aiga)
Farmers in Northern Uganda with an average size of 0.5 acres of land or more grow Oranges (Valencia and Anlin) varieties planted with a spacing of 10 x10 m and integrate them with the use of locally obtained black spear grass and elephant grass on farm as mulching materials and trenches to slow down rainwater runoff while preserving soil moisture for increased production and household income. Citrus orchard of oranges (Citrus sinensis ) with grass mulch and trenches is established on gently sloping land with grasses every year. The trenches are established within the citrus orchard for soil erosion control and environmental and water conservation.To establish this technology the land user will (1) identify an already planted Orchard of Oranges susceptible to soil and water erosion problems, (2) clear the grasses in the garden using a panga, (3) dig the trenches using a hoe, a spade and labour up to a depth of not more than 0.5 centimetres, (4) carry and lay the mulch to the garden using at least 3-4 workers per day with the grass mulch kept at a minimum distance of 20 centimetres away from the plant to allow for air circulation, (5) remove the sediments and re-apply them back to the field once the trenches are filled with the sediments. Mulched grass decomposes over time, improves fertility while trenches allow water harvesting and prevent soil and water erosion. However, the land user needs to be aware that trenches are labour intensive which could be the most expensive input, in addition to the cost of basic construction materials for digging trenches like a hoe, a panga and a spade which are in most cases bought once and used for a longer period of time. The benefits derived from this SLM technology are high in the long run as the technology is suitable for improving soil fertility and controlling soil erosion with the established grass mulch and trenches. Trenches and grass mulch retain water during heavy rains which is utilized by citrus during the dry season. The leaf litter from a citrus garden with minimum tillage when decomposed provides manure to enhance crop production generating increased income from the sale of fruits. However, this technology requires labour for planting, cutting the grass , watering and constructing the trenches which accounts for most of the costs. What is not liked about this technology is that the trenches are not easy to make and are labour-intensive.

The technology relies on use of locally obtained grass mulch within the field.
The technology requires inputs like hoes, pangas and spades which are not very expensive.
Requires more labour for digging trenches and carrying grass mulch at the time of establishment.
