A large proportion of the world tropical region is covered by savannas, which have been little used for agriculture. Locally known as Cerrado, this ecosystem occupies about 20% of Brazilian territory. Preliminary surveys indicate that at least 50 × 106 ha of the Cerrado are of potential use for intensive mechanized agriculture, but development has been limited by soil-related constraints. Most soils are acid and with very low native fertility, especially in terms of phosphorus. Chemical barriers to root growth may cause severe yield losses during dry periods. Field crop responses to lime and fertilizers, obtained during the last 5–8 years, show that once soil-related constraints are removed, high yields can be achieved. This review gives an account of the main lines of research which are leading to economic methods of developing the agricultural use of the Cerrado, and gives future research needs
