Measurements of soil samples from different agricultural land uses over the period 2015-2023 show that phosphorus (P) is deficient in soils of extensive orchards, olive groves and pastures, below optimum in intensive orchards, vineyards and grasslands, and adequate in arable land. The low phosphorus content is mainly due to the natural low content of this nutrient in Slovenian soils and leaching. Potassium (K) contents are generally higher than P, reflecting Slovenia's better natural soil K supply.
