Abstract: A fertilization map creating system includes a growth sensor, a GPS device, and a growth information accumulating part that stores data, a fertilization map being created based on growth data and position data stored in the growth information accumulating part, and the growth information accumulating part storing the position data and the growth data while a tractor drives in a field. The system further includes a growth condition calculation part that obtains a growth condition of previously set each area in the field based on the data stored in the memory; a fertilization amount calculation part that obtains an amount of fertilization of each area based on the growth condition of each area; and a map creating part that creates the fertilization map showing the amount of fertilization of each area obtained by the fertilization calculation part.

Abstract: To provide a method of measuring a state of concrete capable of easily determining or measuring deterioration of the concrete without using a spectroscopy while maintaining the estimation accuracy. The method of the present disclosure emits an irradiation light to the concrete, the irradiation light including a wavelength range of near infrared light related to concrete measurement; and receives a reflection light of the irradiation light P reflected on the concrete. The method determines at least five wavelengths λ1 to λ5, λ6 to λ10, different from each other by PLS regression analysis within a wavelength range of 900 nm to 2500 nm of absorption spectrum, and estimates a degree of neutralization of the concrete caused by calcium hydroxide and a concentration of chloride ion.

Abstract: A plant wavelength sensor device includes a light emission portion for emitting a measurement light P to irradiate a target plant, a light receiving portion for receiving the measurement light reflected on the target plant as a reflected light; and a control section for controlling the light emission portion and the light receiving portion. The control section is configured to emit the measurement light having a wavelength range corresponding to a selected growth parameter from the light emission portion, to receive the reflected light from the target plant with the light receiving portion with respect to the measurement light having the wavelength range corresponding to the selected growth parameter, and to calculate a volume of the reflected light from the target plant as a reflected light volume with respect to the wavelength range corresponding to the growth parameter.

Abstract: To provide a plant sensor device capable of obtaining a parameter to determine a growth status other than a spectroscopy vegetation index without increasing its configuration. The plant sensor device includes a light emission part for emitting a measurement light to irradiate a target plant, a light receiving part for receiving a reflected light from the target plant, and a control section for controlling the light emission part and light receiving part. The control section determines a spectroscopy vegetation index of the target plant by obtaining a reflection rate of the target plant based on the measurement light and reflected light. The control section calculates a distance from the target plant to the light emission part in accordance with the measurement light and reflected light, and determines a plant height of the target plant based on the distance.
