Soil properties vary greatly over space and time; therefore, the precise detection of spatio-temporal variation is essential to understand the dynamic soil conditions and consequently apply site-specific management. This paper aims at studying the spatial and temporal variation in some soil properties within a period of 4 years in a field cultivated by potato crop with a fixed annual compost application. Inverse distance weighting as a deterministic method was used to develop the spatial distribution maps of the studied soil properties (soil reaction, electrical conductivity, cation exchange capacity and soil organic matter). These maps were annually created for the soil properties under investigation, i.e.2019, 2020, 2021and 2022. Results revealed that there was variation over space and time for all soil parameters under study. Spatial maps of soil pH showed an annual change with a temporal increase comparing 2019with 2022. Soil salinity maps revealed a decrease in both spatial and temporal scales. Spatial maps of CEC showed a fluctuation in the spatial distribution as well as from year to year with final improvement reaching a value of 20.4 cmol+/kg. Soil organic matter spatial maps showed an opposite pattern compared withthe other soil parameters where a decrease in SOM was observed comparing the start and end of the whole period of study.
