Data on the physical and chemical attributes of soil from a Caatinga remnant in the Santa Maria da Lage settlement, south-central Sergipe, Northeast Brazil

Average values obtained from physicochemical analyses of soil at a depth of 0–20 cm in a Caatinga fragment located in the municipality of Poço Verde, south-central Sergipe, have been made available (10°44’31’’S, 38°05’53’’W). The method of soil sampling and the chemical and physical analyses used to assess soil fertility were based on Silva (1999).

The study region, located in the Sertanejo pediplain, features dissected surfaces and residual mountains at an altitude of 273 meters (SEPLAG-SE, 2014) and soils classified as Planosol, Halomorphic, and Regosol (SEPLANTEC-SE, 1997). The climate of the region is characterized as semi-arid, with a rainy season in winter (BSh), according to the Köppen climate classification (SEPLAG-SE, 2011; ALVARES et al., 2014). The average annual temperature is 23.7°C, with an average annual precipitation of 780 mm, and the rainy season extends from March to July (SEPLANTEC-SE, 1997; SEPLAG-SE, 2011).
