In the Sudan, it is planted to protect crops from blowing sands. The wood, durable, easy to saw, yet resistant to termites, is widely used in Australia for strong durable construction, interior finish, flooring, cabinetry, furniture, fenceposts, cross-ties, sometimes pulpwood. Australian aborigines made canoes from the bark. Survivalists in Australia and elsewhere might learn how the aborigines obtained water from the superficial roots, usually those ca 3 cm in diameter. The roots were excavated or lifted to the soil surface. Then the root was cut into segments ca 45 cm long, debarked, held vertically, and blown into, the water then draining into the receptacle provided." Chemical Analysis of Biomass Fuels Analysing 62 kinds of biomass for heating value, Jenkins and Ebeling (1985) reported a spread of 19.42 to 18.23 MJ/kg, compared to 13.76 for weathered rice straw to 23.28 MJ/kg for prune pits. On a % DM basis, the wh.plant contained 81.42% volatiles, 0.76% ash, 17.82% fixed carbon, 49.00% C, 5.87% H, 43.97% O, 0.30% N, 0.01% S, 0.13% Cl, and undetermined residue.
