Editor's Notes
- Demonstrates how improved fallows improved soil fertility
- Depicts nodules on âfertilizer tressâ. The fertilizer tree here is Sesbania sesban.
- Shows the trend over time. The Miombo has been cleared for agriculture. Continuous cropping of the cultivated land has mined the land of nutrients. Short term grass fallows (up to 5 years) are traditionally used to allow the land to recover, but the resultant yields are still inadequate. The problem of poor yields for farmers who cannot afford fertilizer can be overcome by adopting improved fallows or other agroforestry options that fix nitrogenâthe most limiting nutrient in the region and also improve infiltration.
- The demand for wood products to meet basic household needs is very high, yet the supply is declining. Woodlots have been tested as agroforestry technologies to contribute towards addressing this problem. ICRAFâs work on woodlots in Southern Africa is concentrated in Tanzania ( Tabora and Shinyanga).
- A five year old acacia crassicarpa woodlot. The woodlots are rotational. That is, they are planted in rotation with Maize to exploit the nitrogen fixing benefits of the trees.
