A fertilizer application related formula for obtaining the necessary amount of fertilizer to be applied is established by analyzing growth information including leaf blade information, fertilizer application information and quality information, all the above information being obtained in advance from a number of grains or grain crops. The formula thus established is stored in the memory. The necessary amount of fertilizer to be applied for each specific period for grain crops which are presently under growth is calculated by applying to the above formula, growth information of the grain crops presently under growth and target quality information. The growth information includes leaf blade information in relation to a specific period. The results of the calculation are displayed or printed out. A method and an apparatus for estimating a quality or yield of grains prior to the harvesting is also disclosed.

    摘要: A method for measuring ash content of food stuff is carried out by 1) preparing, with respect to food stuff samples whose ash content values are known, a calibration curve by a non-linear analysis of absorbance values and the known ash content of each sample, the absorbance values being obtained by irradiating light having particular wavelengths containing at least an ultraviolet ray band wavelength, the particular wavelength being specific to organic ingredients well coupled to inorganic ingredients which result in the ash content, and 2) deriving, with respect to a sample whose ash content value is unknown, an ash content value of the sample from absorbance values obtained by irradiating, on the sample, light having the particular wavelengths containing at least the ultraviolet ray band wavelength and from the calibration curve prepared in advance by the non-linear analysis. An apparatus for carrying out the method includes a light source section, a photo detecting section, a storing section for storing the calibration curve, and a calculation section for calculating, with respect to a sample whose ash content value is unknown, the ash content value based on the absorbance values and the calibration curve stored in the storing section. It is possible to speed up the measuring operation and to improve the measuring precision.
