<p>PROBLEM TO BE SOLVED: To provide a fertilization design determination method and a fertilization design system capable of performing an optimal fertilization design for crop growth by acquiring true situation of soil.SOLUTION: The fertilization design determination method is provided for analyzing an excess/deficiency state of nutrient required for raising respective types of crops in a prescribed soil and determining a soil processing method. The fertilization design determination method includes: a sample collection step of collecting a prescribed amount of specimen from the prescribed soil; an analysis step of performing a chemical analysis of the collected specimen to acquire chemical data and analyzing physical properties to acquire physical data; and a design step of determining the fertilization design for the soil on the basis of the chemical data and the physical data. The physical data in the analysis step are a measured apparent specific gravity calculated by substituting a dry soil volume, a field-moist soil volume, and a dry soil mass, a hardness value of the soil, and a water permeability value of the soil.</p> |
