Ground composition data for the southernmost area of Lérida province, NE Spain

More than 3000 physical, chemical and morphological data of soils described between December 1980 and July 1981 in the southernmost part of the province of Lérida, NE Spain, are collected in this dataset. The soils are located between the coordinates 41.62°N 1.06°E, and 41.28°N 0.34°E.
Most of the soil samples were taken in backhoe dug pits where their profiles were described. The data —presented here in an Excel spreadsheet— come from the book by J. Porta & R. Julià (eds.) published in 1982 with I.S.B.N. 84-5008771-6. Moreover, two chapters were scanned from this book and included in this dataset as “Description.pdf” and “FormationClassification.pdf”. The author did not proofread the galley proofs of these chapters. The data contained in “Description.pdf” were manually transcribed in 2025 to the excel file “ProfilesLerida04clas.xlsx”.
Care must be taken with the location coordinates given the non-correction of the galley proofs and because the resources available to us 45 years ago were quite rudimentary. The excel file “ProfilesLerida04clas.xlsx” incorporates the correction of obvious errors in the coordinates and their transformation to ETRS89 from the notations used in 1980-81. The help of Ms. Rosa Gómez-Báguena with the coordinates is greatly appreciated.
We also present the file "1989 XVI Reun.SECS Lérida suelos secano", a report including discussion and data about the studied soils.
