Conteúdo: 	Sandy soils are deep soils with low clay content (lower than 150 g kg−1) and are well drained and located in fat-to-mildly undulating terrain. However, they have chemical (i.e., low fertility, high acidity level, and low cation exchange capacity) and physical (i.e., low water holding capacity, susceptibility to erosion, and compaction) limitations for plant growth. Sandy soils cover approximately 8% of Brazil; they cover 20% of the main current agricultural expansion region in the country, which corresponds to Maranhão, Tocantins, Piauí, and Bahia states (referred to as Matopiba). Until recently, these soils were classifed as having limited suitability for agriculture, but advancements in research and technologies made these soils productive. These technologies include improvements in soil fertility, crop rotation, intercropping, cover crops, implementation of integrated crop–livestock–forestry systems, etc. Given the problems presented by these soils, it is essential to adopt proper techniques to help manage them in order to ensure the sustainable development of Brazilian agriculture and livestock.
