Örtü Altı Bitkisel Üretiminin Sulama Yönetiminde Toprak Su İçeriğinin Belirlenmesi.

The need for water increases significantly due to the increase in temperatures and the decrease in water resources with climate change. In increasing agricultural production, along with other factors, it is undeniable that the share of irrigation is very large. The general practice in irrigation is to wet the root zone water content until it reaches field capacity after the irrigation time is determined. However, one of the most fundamental issues in planning a correct irrigation management is the determination and monitoring of soil water content. For this reason, in this study, it was aimed to determine the possibilities of determining and monitoring the soil water content of the plant root zone. The research was carried out in a greenhouse at Akdeniz University Faculty of Agriculture Research and Application Farm in Antalya, where greenhouse crop production is intense. In the study, the usability of the Profile Probe PR2 method, which is an indirect measurement method in determining the soil water content, was investigated. In the evaluation of the Profile Probe PR2 method, the gravimetric method, which is a direct measurement method for soil water content, was used as the basic tool. In the research, it was concluded that the soil water content can be determined quickly, practically and easily with the Profile Probe PR2 method. However, if it is preferred to monitor the soil water content with the Profile Probe PR2 method, it is also recommended to perform a detailed gravimetric calibration study for each soil condition.
