An underdeveloped country wishing to establish a fertiliser industry ought surely to begin by examining the locally available raw materials. In Tanzania, for example, a report in 1961 drew attention to an anhydrite deposit at Kilwa which could have been used to produce cement, gypsum, and sulphuric acid.2 The latter if combined with ammonia from the oil refinery would have given ammonium sulphate, the fertiliser most commonly used in Tanzania. The report also noted three deposits from which phosphatic fertiliser could have been made. However, the development of these local resources was rejected on the ground that for plants of an efficient size the local market would not be able to absorb all the fertilisers.
