This dataset contains the carbon stock in different pools, including soil up to 300 cm deep, in different land uses, in the Atlantic Forest in Brazil. The data was collected in a rural settlement belonging to the MST (Landless Workers' Movement, or Movimento dos Trabalhores Sem Terra in Portuguese), in the Ipanema Settlement, in Iperó, state of São Paulo, Brazil. The farmers implement different land restoration approaches in order to restore the land. This study evaluated the carbon sequestration after land restoration, or the climate change mitigation potential of different restoration approaches, when including deep soil (300 cm) in the assessment. The unit of the carbon stocks is Mg ha-1. Soil and roots were collected in 6 layers, as follows: 0-20, 20-40, 40-100, 100-150, 150-200 and 200-300 cm. In addition to soil, carbon stocks were also determined in the aboveground biomass, necromass, fine roots and coarse roots. Six different land uses were assessed: Agriculture: 1) areas under long term (> 25 years) agriculture; 2) Agroforestry system in intermediate stage: successional agroforestry system, which is a mix of native and fruity exotic species planted in rows, and cropland between the rows, at the age of approximately 5 years old; 3) agroforestry system in advanced stages, which is the same as land use 2, but in later stages (approximately 19 years old), where trees grew and canopy closed, forming a structure similar to a secondary forest; 4) reforestation with mixed native species: planting of native species in rows following regular spacing (usually 3 meters wide), at a age with around 16 years old; 5) natural regeneration: areas set aside where regeneration of trees took place, after approximately 17 years after fencing off; 6) secondary forest: forest patches remnants, without management and targeted human interference. Land uses 2, 3, 4 and 5 are different restoration approaches and were under agriculture (land use 1) before land use change.
