発明の名称 (英語) SOIL ANALYZING DEVICE AND SOIL ANALYZING METHOD UPDATE
発明の概要(英語) [Problem] To provide a soil analyzing device and a soil analyzing method capable of accurately obtaining a cation exchange capacity (CEC) which serves as an indicator for evaluating the fertility of soil.
[Solution] This soil analyzing device is provided with: a sensor 10 including an exciting coil 11 and a detecting coil 12; a measuring unit 20 which, in order to apply an alternating magnetic field to soil being analyzed, generates, for each frequency, an excitation signal to be input into the exciting coil 11, and processes a detected signal that is output from the detecting coil 12 upon application of the alternating magnetic field to the soil being analyzed; a storage unit 33 which, in relation to a plurality of soils having different components, stores data related to a correlation between a quantitative value of a soil fertility characteristic including the CEC, and an estimated value of the soil fertility characteristic including the CEC, obtained from a processed detection signal measured using the sensor 10 and the measuring unit 20; and an estimating unit 34 which, on the basis of the detection signal obtained by using the sensor 10 to apply the alternating magnetic field to the soil being analyzed, and subjecting the resulting signal to processing using the measuring unit 20, uses the data stored in the storage unit 33 to estimate the soil fertility characteristic, including the CEC, of the soil being analyzed.
従来技術、競合技術の概要(英語) BACKGROUND ART
In order to improve the productivity of agricultural products is, to appropriately grasp the fertility of the soil needs. As an indicator of the fertility of the soil, the soil to supply nitrogen and the soluble, soluble phosphate lies in a feed, the total phosphorus, total carbon, the total nitrogen, K, Ca, mg, Fe, Al, Na, CN ratio, soil fertility trait CEC(Cation Exchange Capacity) of the present invention. For example, the feed amount of nitrogen and the variable to analyze, using a phosphate buffer solution of the extracted soil organic matter visible absorption spectroscopy or ultraviolet absorption spectroscopy liquid or, near-infrared reflection spectral uses a method has been proposed. A part of the inventors of the present invention, these indicators are obtained simply as the method, excitation light is irradiated onto soil, by analyzing the fluorescence spectrum from the soil, soil fertility trait has been proposed a method to estimate (Patent Document 1).
