Concentrations of plant available P are (too)low in the topsoil of extensive orchards, olive groves and pastures, below the optimum in vineyards and grasslands, suitable on fields and elevated in greenhouse soils. K concentrations are low in soil of olive groves, meadows and pastures, whereas the elevated contents are in fields, intensive orchards, and vineyards, and excessive in the greenhouses. The organic matter content is approximately 4% in the field soils, orchards, and greenhouses; in grassland soils the content is higher (5%) and lower in olive groves and vineyards due to the climatic zone and the cultivation methods. The soil organic matter content in the Slovenian agricultural soils is comparable to the values in other countries of similar climatic zones. The soil pH is lower in the intensive orchards and the highest in olive grows, thus appropriately reflecting the natural soil acidity.

The indicator shows the state in the period 2012–2015 and does not reveal a trend direction yet; trends will be more discernible at the next indicator update (after the next 4-year period).
