Abstract

Strict control of the amount of water in soils is one of the most important environment factors for crop growth, so it would be useful to be able to determine the amount of water distributed through the soil at all times. We have therefore proposed a new system for measuring the amount of water in the soils. It achieves this by measuring transitions in the temperature distribution in the soil using infrared ray sensors. The ground surface temperature obtained from infrared ray sensors is different with and without the presence of water. Therefore, we can determine the amount of water that is present from transitions in the temperature distribution when using in this system. Because it uses infrared ray sensors, this system has the great advantage that is enables non-contact, real time measurements of the distribution of water in the ground. If this system were to be developed further, increased efficiency might be expected in some areas of agricultural fields.
