Lugar

Kamuli, Kaliro, Nakaseke, Nakasongola, Lyantonde and Sembabule districts of Uganda.|

Breve descripción del entorno natural en el lugar especificado

Breve descripción de las principales actividades, por objetivo

1. Establishment of permanent planting basins across the slope before onset of rains;
2. Application of manure or inorganic basal fertilisers in the basins and covered with soil;
3. Ensure early planting at onset of rains;
4. Application of pre-emergence herbicides.
1. Ensure optimum plant populations in each basin at planting and take care to increase the survival rates;
2. Mulch the established crop to conserve soil moisture, increase soil organic matter and suppress weeds;
3. Apply top dressing fertilisers in each basin as appropriate to increase crop vigour, biomass, resistance to pests/ diseases, and effective flowering and filling;
4. After harvesting, cut down the crop straw and use it to mulch in-between the planting rows.|5. Open the planting basins for next season planting after harvesting the previous season's crop when the soil is still soft;
6. Implement a crop rotation system for the next planting season.

Breve descripción y especificaciones técnicas de la tecnología

The identified site is slashed in preparation for construction of permanent planting basins. The basins are constructed using a hand hoe across the slope, with dimensions  of: width 15cm; depth 15cm;  and length 35cm. The distance from one basin to the next in the row is 35cm and the distance between rows is 75cm. Preparation for planting includes application of agricultural lime in basins where soils are acidic, application of basal fertilisers especially Di-Ammonium Phosphate (DAP) one soda bottle top. Where not affordable, application of organic manure (one half-litre cup) should be added and covered with soil up to 10cm depth. Select clean and healthy seeds and ensure early planting at the onset of rains. Seed rates e.g. fr maize 3 seeds per basin, beans 6 seeds per basin, ground nuts 6 seeds per basin, soyabean 8 seeds per basin and cotton 4 seeds per basin. Apply Glyphosate herbicides at pre-emergence stage. Apply additional mulch in-between rows after the plant have established. For cereal crops, you may apply nitrogen fertilisers.|

N/A

Describa los impactos in situ (los dos principales impactos por categoría).

Under the conventional cropping system, farmers on average receive maize yields of 750 kg/ha. Farmers who practiced CA received yields between 1500-2250 kg/ha in the first cropping season and this is expected to increase a they perfect the practice.|
None
Increased yields from CA practice provide additional benefits of food security and better incomes.
Efficient nutrient management increased he biomass production which provides mulch and increases soil organic matter, hence higher productivity of the soil.|
With the continuous return of crop residues as mulch over soil, there is increasing build up of soil organic matter.|
Farmers are able to produce more with less labour as CA helps them to distribute their labor e.g. by preparation of permanent planting basins in the dry season when labour is idle and reduce the drudgery by using herbicides for weed control. This is frees school children and women to do other work.
None
The minimum tillage drastically reduces soil erosion. The permanent planting basins constructed across slopes act as sinks to absorb run-off water, hence preventing erosion. Mulching equally deters movement of soil particles during rains.|

Describa los dos principales impactos fuera del lugar (por ejemplo, que no se registran en el lugar, pero sí en las zonas próximas).

Controlling soil erosion in annual cropping systems represents a significant step in controlling siltation of major water bodies f international importance such as Lake Victoria and Lake Kyoga.
Carbon sequestration - Continuous application of organic matter through return of residues increases soil carbon.

Impacto en la diversidad biológica y el cambio climático

Justifíquelo:

Continuous application of crop residues increases soil organic matter and below ground biodiversity as humus is a source of food for many microorganisms. The added OM contributes to sequestration of carbon contributing to climate change mitigation while the increased resilience of the crop to drought with application of OM contributes to climate change adaptation.

¿Puede identificar las tres principales condiciones para el éxito de la práctica óptima/tecnología presentada?

Improved incomes - this provided a big incentive for the farming groups as they are able to meet their household needs and save some money for investment.
Technically sound but simple - The practice is very simple, does not require specialised skills and can be easily done by men, women and chaildren.|
Cost effective operations - The activities are cost effective since operations are not labour intensive and the labour requirements are spread out throughout the year, even in the dry season when labour is idle.|

En relación con los recursos humanos

1. The practice has been effective in ensuring distribution of labour as opposed to the labour bottlenecks created by the conventional farming systems.
2. The use of herbicides to control weeds saves a lot of time and labour that can be put to other productive uses or even give the farmers time to rest in preparation for other activities.

En relación con los aspectos técnicos

1. The practice has proved to be technically simple and can be easily carried out by all classes of farmers.
2. The partnerships created enable the farmers to access genuine inputs locally ad timely to enable them plant the crops on time.
