Abstract: A system and method for providing a fertilizer recommendation for an agronomic field based on a direct measurement of a crop nutrient level at a measurement location, including receiving field and remote data. Optional approaches include adjusting the fertilizer recommendation based on at least one of the received field, farm and/or weather data. Alternatively, based on field data, at least one measurement region for carrying out a measurement for providing a fertilizer recommendation is determined. Optional approaches include receiving remote data, farm data and/or weather data to manage the improve the measurement region determination.

Abstract: The invention relates to a handheld device and method for determining a status of a plant. The device includes a multi pixel digital colour sensor, a light source arranged for providing broadband illumination, wherein the light source and the multi pixel digital colour sensor are arranged in substantially the same plane, a light guide for guiding the light from said light source into the direction of the multi pixel digital colour sensor, a sample space, provided between the multi pixel digital colour sensor and the light source, for insertion of at least a part of the plant therein, and a processing unit configured for controlling at least the multi pixel digital colour sensor and the light source.

Abstract: The invention relates to a system and method for determining a status of plants. The system includes a light transmitter arranged for providing broad band illumination to one or more plants. The system includes a light receiver including a plurality of receiver channels, the receiver channels arranged for receiving light from said one or more plants in mutually different wavelength bands. The system includes a processing unit arranged for determining a status of said one or more plants on the basis of light received by the plurality of receiver channels. The transmitter may be arranged for transmitting bursts of modulated light.

Abstract: The invention relates to a handheld device and method for determining a status of one or more plants. The device includes a digital color camera arranged for obtaining a color image of plants within a field of view, a light source arranged for providing broadband illumination to the plants within the field of view, and a processing unit arranged for controlling the camera and the light source for obtaining a first image of the plants while the light source illuminates the plants with broadband illumination, and obtaining a second image of the plants while the light source does not illuminate the plants.

Abstract: In a method and device for measuring a height of an agricultural product above ground using a mobile communications device, the method includes positioning the communications device above the agricultural product and determining a distance between the communications device and the agricultural product using a built-in sensor of the communications device. The height of the agricultural product is determined on the basis of the determined distance.

Abstract: A method of partial area-specific-fertilization of plants which, under natural light during the fertilizer application, the chlorophyll content of the plants is ascertained by means of sensors by optical reflection measurement in the visible and near infrared spectral range, the chlorophyll content is registered and from the chlorophyll content a measurement of the nutrient state of the plant is determined and from the nutrient state of the plants a computer controls the fertilizer quantity to be applied, characterized in that the reflection measurements are taken simultaneously as inclined measurements with respect to the nadir with measurement devices oriented oppositely to one another free from shadows with light guides an the influence of the solar azimuth angle is eliminated by detecting the noise signals from all measurement directions.
