The technology is mostly promoted by farmers in Kampala District, Central Uganda and other parts of the country. The technology is seen as a cheap and healthy solution to food insecurity and runaway unemployment in Kampala’s slum. It is preferred by farmers because it's cheap, high-yielding and promoting food security while maximizing land and water use.
This technology is practiced in the slum area of Kisenyi 2 zone, Kamokya parish, Kampala District and was established in 2015, where the farmer got farming training from Kampala City Council Authority through demonstrations in the urban farming program. The main reasons for its establishment were; the ease to establishment and management, space optimization, no special skills required and affordability.
To establish such a technology the farmer started by collecting huge sacks of banana leaves that had been dumped around the neighborhood.
Black soil was mixed with chicken manure that was available. Small pebble stones were added and strong sticks placed in the middle of the sack, right from bottom to top. The sack was then filled with soil, leaving the stones erect in the middle. For an optimal production, the farmer used bags with a containing capacity of 50 to 100 kilograms. Additonal items were one polyethylene (food-safe bag. ie: rice bag) and a pipe of the height of the bag, opened at both ends, 15 to 20cm long.
The complete system consists of 50 kilos of soil, 25 kilos of fertilizer (compost, manure) which is adjusted according to the
quality of the soil plus 15 kilos of stones (3 to 7 cm diameter).
In some sacks the farmer grows tomatoes, cabbages and carrots. Usually the crops with big roots, like carrots, go on the top, and the sides are reserved for cabbages with small roots, she says. The sack garden is watered on a daily basis, twice a day if the weather is dry and once a day if the weather is humid. There is no such a thing as a crop-growing season. The garden is ever green, even during the dry season. The farmer makes 0.6$ selling spinach to neighbors, and 0.84$ selling produce to the market. This translates to about 27.8$ per month, after deducting expenses.
Sack gardening is very advantageous to the farmer and other farmers are trained in the technology by the farmer who started it. The farmer receives an equivalent of 1.39$ a day. For 20 training days this totals to 27.8$ a month from tutoring a women group in Kamokya. This additonal income helps the farmer securing enough money to meet needs like school fees, food and utility payments. It also provides a secure source of nutritional food, facilitates growing of vegetables in areas without suitable soils or adequate space, promotes efficient and effective utilization of available water and nutrients.

The farmer acquired skills in sustainable sack garnening
จำนวนก่อน SLM: Vegetable quality were vere low
หลังจาก SLM: Improved quality
She maintains the garden on a daily basis
จำนวนก่อน SLM: She didnot spray the plants
หลังจาก SLM: Sprays the plants as directed
The farmer has enough skills in sack gardening
She use compost manure
จำนวนก่อน SLM: She used to 0.6$ day
หลังจาก SLM: She gets 0.84$ a day
Reduced maintenance costs and high yields
จำนวนก่อน SLM: Vegetables were bought from the market
