Abstract: A fertilization amount information management device and the like are provided with which a manager of a farm field or the like can be free of cumbersome operation of drafting fertilization amount plans for entire farm fields and with which a dedicated fertilization amount plan tailored for an actual condition of each farm field can be drafted.A fertilization amount information management device 10 includes a display unit. Fertilization amount plan information 56 on each of farm field portions that are portions of a farm field is generated based on measured growth information 24 that is growth information on a measured plant and is displayed on the display unit 16. Corrected fertilization amount plan information 65 indicating correction needed for each of the farm field portions is able to be input based on the fertilization amount plan information for each farm field displayed on the display unit.

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.

Abstract: A method of measuring a state of concrete includes emitting an irradiation light to the concrete, the irradiation light including a wavelength range of near infrared light related to concrete measurement; and receiving a reflection light of the irradiation light P reflected on the concrete. 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, are determined, and a degree of neutralization of the concrete caused by calcium hydroxide and a concentration of chloride ion is estimated.
