WOS: 000384966000043 The aim of this study is to investigate soil temperature activity on soil water content under organic and conventional managements at the hazelnut orchards. Soil temperature (ST) and soil water content (SWC) variations under organic and conventional managements at the hazelnut orchards were continuously monitored by using high frequency ECH2O-5TE probes connected to a 5 channel Em50 data logger during data collection in the growing season of 2014. Investigations were performed at four different soil layers (0-30, 30-60, 60-90 and 90-120 cm) under the selected tree canopy area for each management during the data collection. In five days of post-rainfall episode in July 2014, organic management become more effective on regression relationships of ST influences on SWC at all soil layers except 0-30 cm layer when compared with conventional management in hazelnut orchards. The highest value of liner regression equation between SWC and ST was obtained at 30-60 cm soil layer (R-2=0.95) under organic management of that episode. On the other hand, the highest values of linear regression equation between organic and conventional managements in hazelnut orchards for SWC and ST were acquired at 0-30 cm soil layer (R-2=0.98; p < 0.01) in ten days of post-rainfall episode in August and at 30-60 cm soil layer (R-2=0.98; p > 0.01) in five days of post-rainfall episode in July for, respectively. Therefore, organic management at hazelnut orchards could be evaluated as a valuable alternative for such areas where hazelnut trees are grown by rainfed.
