Abstract: A fertilization design device calculates a fertilization amount of a field to be fertilized and includes the following units. A database reception unit receives one or both of growth data indicating growth potential of the field and soil data indicating plant growth potential of soil in the field and receives position data as position coordinate information for the field. A designated position reception and retrieval unit receives a freely selected position designated by a user and retrieves information of the freely selected position from the position data. A user input fertilization amount value reception unit receives a fertilization amount value freely set by the user for the freely selected position or for a range including the freely selected position. A calibration curve generation unit generates a calibration curve, based on one or both of the growth data and the soil data, the position data, and the fertilization amount value.

Abstract: A spectral curve acquiring device comprising: a light receiving optical system (6) for irradiating an irradiating light, a light receiving optical system (8) for dispersing and receiving a reflected irradiating light reflected by an object to be measured (7), a distance meter (4) for measuring a distance to the object to be measured, a storage module (25) for storing a plurality of reference spectral curves prepared based on a light receiving intensity for each wavelength at the time of measuring a white reference plate with different distances, and a control arithmetic module (24), wherein the control arithmetic module obtains a light receiving intensity of the dispersed reflected irradiating light for each wavelength based on the reference spectral curve corresponding to a distance to be measured, corrects a measurement spectral curve prepared based on the light receiving intensity, and prepares a spectral reflectance curve.

Abstract: A technique is provided to enable low-cost control of amounts of fertilizer applied. A control device controls a currently used agricultural machine that applies fertilizer to a crop while traveling through a field. The control device includes a growth data receiving unit, a fertilizer application amount value calculator, and a speed signal generator. The growth data receiving unit receives growth data that is obtained by sensing a growth condition of a crop at each location in the field. The fertilizer application amount value calculator determines an amount of fertilizer on the basis of the growth data. The speed signal generator generates a speed signal to cause the agricultural machine to travel at a speed corresponding to a variable value of an amount of the fertilizer to be applied at each location in the field.

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: A growth information management device and the like with which growth information acquired from a plurality of farm fields can be easily divided or processed in other like manners. A growth information management device 10 generates boundary information on farm field information based on measured growth information 24 that is plant growth information that has been measured, generates independent farm field information 53 sectionalized based on the boundary information, and converts the measured growth information corresponding to the independent farm field information into growth level information 45 that is information indicating a level of growth of a plant and displays the growth level information on a display unit 16.

Abstract: A technique enables intuitive understanding of a directional relationship between a photographed image and a wide area image, such as an electronic map. An image processing device includes a display controlling unit that displays a quadrangular-shaped photographic image, which is photographed from an aerial vehicle, displays a mark indicating a photographing position of the quadrangular-shaped photographic image, on a wide area image, and performs highlight display in accordance with a corresponding relationship between a direction of the quadrangular-shaped photographic image and a direction of the mark.
