For centuries the Neretva confluence dictated the scope of human civilization and activities on its land. Climatic characteristics of the Neretva valley were caused by the proximity of the Adriatic Sea and the surrounding relief. In the Neretva confluence there are two basic prerequisites that enable the development of intensive agriculture. These are the Mediterranean climate and the presence of alluvialsoils formed by sedimentation which are anthropogenized and its high agricultural potential is exploiting. Using all the advanced methods of cultivation and intensive land reclamation operations, the scale of production is visibly growing in the last decade leading to the inevitable adverse changes in the enviroment. On the one hand there is a growing danger of flooding, and on the other hand there is a long dry period, while overexploitation of groundwater and surface water causes sea intrusion.The Neretva confluence is a very important rural area in Croatia, especially when it comes to the production of early vegetables and citrus, so all its problems should be seen as both social and economic aspects. A large number of people are directly and indirectly dependent on agricultural activity, therefore, to maintain the agricultural production or to plan the guidelines for the recommendations of agricultural production, the land monitoring and assessment are necesarry. The aim of this study was to determine the stage of soil salinity and concentrations of available nutrients in selected tangerine orchards on amelioration area Vidrice in the Neretva valley. The sampling was conducted in ten orchards which all differ in the way of land management. The soil was sampled boring to 1m in segments of 25cm. The pH value of the studied samples are in the range of 7.6 to 8.2 which varies depending on the depth of the soil. According to the electroconductivity ground in the first three depths, up to 75cm, can be classified as unsalted and at the depth of 75-100 cm soil show slow salinity. In the analyzed soil samples there is no visible difference in the amount of organic matterin surface and subsurface layer. The analysis of the concentration of the plant accessible phosphorus and potassium has been shown that there was no statistically significant difference in the concentration of phosphorus or potassium per descussed depths, but there is a visible increase in the concentration of both elements in general indicating a recent application of fertilization and the use of irrigation systems.
