Today, environmental monitoring is increasingly important in arable crop production due to the importance of weather, sustainable nutrient and water management. This paper presents a new innovative technology based on wireless data link and transmission and its results for monitoring soil ammonia emissions using Internet of Things (IoT) technology based on the measurement of environmental characteristics could be a practical method in the future. It is a monitoring system for sustainable and environmentally friendly crop production. The sensors used will ensure the monitoring of soil ammonia emissions, a method that provides fast and accurate monitoring. The results show a periodic trend in NH3 fluxes, with higher amounts in the spring (warmer) periods after nitrogen fertilisation. Results of multivariate linear regression analyses indicate that soil moisture, temperature, humidity and air pressure significantly influence NH3 emissions.
