Soil Chemical and Physical Properties of an Olive Field in Messinia, Peloponnese, Greece

Abstract This dataset contains soil analysis results from olive agricultural fields in Messinia, Peloponnese, Greece (spatial extent: 21.65-22.45°E, 36.7-37.4°N). Soil samples were collected from 0-30 cm depth and analyzed by ARAL Laboratory (Agropyrgos, Athens) in November 2022. The dataset includes physicochemical properties including pH, electrical conductivity, organic matter content, macro and micronutrient concentrations, and soil texture analysis. Data are particularly relevant for Mediterranean agricultural systems and olive cultivation. Quality Control Analysis performed by certified laboratory (ARAL E.P.E.) Results include quality assessment and agricultural interpretation Reference ranges provided for all parameter Measured Parameters Physical Properties Soil texture: Sand, silt, and clay percentages Texture classification: Silt loam (SiL) Chemical Properties pH: Soil reaction (slightly acidic: 6.0) Electrical Conductivity: Soil salinity indicator (0.12 mmhos/cm - low salinity) Calcium Carbonate: Active and total CaCO₃ content Organic Matter: 2.75% (slightly low) Macronutrients Nitrogen (N): Available nitrogen content Phosphorus (P): Available phosphorus Potassium (K): Extractable potassium Calcium (Ca): Extractable calcium Magnesium (Mg): Extractable magnesium Micronutrients Iron (Fe): Extractable iron Manganese (Mn): Extractable manganese Zinc (Zn): Extractable zinc Copper (Cu): Extractable copper Boron (B): Extractable boron Analytical Methods Extraction method: Ammonium acetate (1N CH₃COONH₄, pH=7) for cation exchange Analysis conducted according to: Standard soil analysis protocol Data Quality Statement This dataset represents a single soil sample analyzed for agricultural assessment. While representing point data, the results are typical of olive soils in the Messinia region and provide valuable baseline information for Mediterranean agricultural research. The sample was taken from a pilot olive field used in the context of a Horizon Europe project, aiming to support sustainable farming practices and soil health.
