Salt distribution in hydroponically grown melon (Cucumis melo L.) on peat

In order to determine horizontal and vertical salt distribution in peat as one of the most commonly used organic hydroponical substrates, investigation has been conducted with four levels of electrical conductivity (EC) in the nutrient solution (2, 4, 6 and 8 dS m-1). After five weeks fertigation of melon (Cucumis melo L.) with saline solutions, on each experimental plot was measured EC of substrate with a conductometer. The arrangement of measurements was according to ordinary grid with distance of 7 cm on two depths (3 and 6 cm). For each treatment were made a 3-D maps of salt distribution in peat bags. An average EC value for both depths at each treatment was 17-55% higher in comparison to the delivered nutrient solution. The lowest EC values of substrate were detected under drippers and around of the bulk root zone. The analysis of the horizontal salt distribution have shown that the EC values have been reduced in the direction from the edge of the bags to the plants, while to the center of the bags EC values again have been increased. The highest salt concentrations were determined on the edges of peat bags and in the center between two plants.
