Advanced monitoring system for agroecosystems threatened by salinization and pollution

Although the problem of sea intrusion and salinization of surface and groundwater, and thus the risk of land degradation, occurs throughout the coastal area of Croatia. The objective of this paper was to investigate and compare two different soil monitoring approaches, classical long-term monitoring and monitoring using automatic soil sensors at two locations in Neretva River Valley. For SMS1 mean values for EC were similar both in long-term and automatic sensor monitoring. At SMS2, mean EC value obtained by the sensors was higher compared to long-term monitoring. Variation coefficient on SMS1 vas low in both monitoring approaches indicating low soil EC varibality in the profile. On the other hand, variation coefficient was high at SMS2 especially in the long-term monitoring indicating high soil EC variability in the profile.
