Professor Ayyar Bendor of the Geography Department of Tel Aviv University in Israel has developed an optical soil monitor that can help researchers and farmers understand the condition of the soil and monitor the impact of climate change on the environment.
This soil monitor is in the form of a pipe. After it is inserted into the soil, it can obtain real-time information about pollution and soil composition, and input the analysis data of soil chemistry and physical properties into a computer or handheld device. Farmers can grasp the soil through it. The composition of minerals, know where is suitable for cultivation, where is not suitable; this instrument can also find out whether the soil needs water or whether it is polluted, and its monitoring quality is comparable to the monitoring results of large laboratories.
In addition, large-scale soil monitoring is a huge time-consuming and laborious project. Sometimes the soil map of an area will only be re-drawn once every 10 to 20 years. In order to grasp the soil characteristics in different places, the staff have to do a lot of hard work, and even use large machinery to excavate soil samples.
The use of this soil monitoring instrument is much simpler, can be implemented with a small number of personnel, and can be carried out year by month; if the monitoring range is large, you can also use aircraft or satellite wireless remote monitoring to obtain timely information on climate change. Accurate soil maps in key years have practical significance.
Professor Bendor said that when it comes to climate change, most people know that temperatures are rising and glaciers are melting, but it remains a mystery what impact global warming will have on soil and water sources. He hopes that the technology he developed will eventually help unravel this mystery.
