KyivWhy Анна Олексієнко created the Agrospecter.
According to international analytical data and research in the field of precision agriculture, a mismatch between the selected agricultural crop and specific soil-climatic conditions, as well as delayed selective diagnostics, lead to losses of 30–40% of potential yield even before the end of the growing season.Today, farmers and agronomists face a serious barrier: traditional laboratory soil analysis is a slow and costly process. Sample collection, transportation, and waiting for laboratory results usually take from several days to several weeks and require significant financial costs. During a rapid sowing campaign or critical plant growth phases, such delays make it impossible to make quick decisions and respond promptly right in the field. Because of this, farmers are forced to act "blindly," risking the loss of yield and significant investments in seeds and fertilizers.The "AgroSpecter" portable analyzer completely solves this problem by providing accurate physico-chemical express analysis data right in the field within seconds. The device allows an agronomist to instantly calculate the suitability index of a plot for a specific crop, locally optimize fertilizer application, and preserve up to 40% of potential yield through accurate, timely, and well-grounded decisions.
How the Agrospecter works.
At the heart of the innovative operation of the portable express analyzer lies the synergy of advanced Near-Infrared Spectroscopy (NIRS) technology and built-in artificial intelligence algorithms. This comprehensive approach allows the capabilities of a stationary agrochemical laboratory to be transferred directly into field conditions, ensuring a complete analysis cycle within seconds.The device's operation consists of four sequential high-tech stages:1. Contactless scanning and optical isolation:When the operator points the device at the soil plot being studied and presses the trigger button, a laser pointer is activated for precise positioning. At the same time, the built-in infrared emitter begins illuminating the sample with a directed beam of rays. The device's design is equipped with a special light-shielding hood — a recessed casing for the optical unit — which completely blocks extraneous sunlight and external interference during measurement, guaranteeing high signal purity and measurement accuracy.2. Optical reading and spectral fingerprint:The device's optical system, based on multispectral sensors, instantly captures the intensity of light reflected from the soil at various wavelengths. In physics and agrochemistry, every substance (humus, water, mineral compounds) has its own unique optical spectral fingerprint. The sensors break down the received signal into spectral components and transmit these raw numerical data arrays to the built-in microprocessor (the
