A plant of the tropics, where it is found at elevations up to 2,900 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 30°c, but can tolerate 12 - 45°c[418 ]. The mature tree may tolerate temperatures down to around -5°c for a short duration, but it cannot withstand repeated frosts and young growth can be killed at -1°c[418 ]. It prefers a mean annual rainfall in the range 300 - 500mm, but tolerates 200 - 600mm[418 ]. Requires a sunny position. Succeeds in shallow soils of low fertility and in saline soils[303 , 418 ]. Prefers a pH in the range 6.5 - 7.5, tolerating 6 - 8.5[418 ]. Established plants can withstand 8 - 11 months of annual drought[418 ]. An aggressive plant, it may easily become a weed[418 ]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[755 ].

Carbon Farming

• Agroforestry Services: Nitrogen  Plants that contribute to nitrogen fixation include the legume family – Fabaceae.
• Fodder: Bank  Fodder banks are plantings of high-quality fodder species. Their goal is to maintain healthy productive animals. They can be utilized all year, but are designed to bridge the forage scarcity of annual dry seasons. Fodder bank plants are usually trees or shrubs, and often legumes. The relatively deep roots of these woody perennials allow them to reach soil nutrients and moisture not available to grasses and herbaceous plants.
• Fodder: Pod  Fodder plants with pods.
• Management: Coppice  Cut to the ground repeatedly - resprouting vigorously. Non-destructive management systems maintaining the soil organic carbon.
• Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
• Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
• Staple Crop: Balanced carb  (0-15 percent protein, 0-15 percent oil, with at least one over 5 percent). The carbohydrates are from either starch or sugar. Annuals include maize, wheat, rice, and potato. Perennials include chestnuts, carob, perennial fruits, nuts, cereals, pseudocereals, woody pods, and acorns.
