A soil measuring apparatus, comprising:

• detecting means for acquiring measurement data from a soil of a measurement site;
• and
• processing means for calculating soil properties based on said measurement data acquired by said detecting means,
• wherein the processing means comprises a model for processing said measurement data, and wherein the model is determined based on information related to a soil type and a water content of a soil of the measurement site.

A soil measurement assisting device for a soil measuring apparatus that measures properties of a soil, comprising:

• storage means for storing soil measurement data correlated with at least one selected from a soil type, information related to a water content of the soil, a model for calculating soil properties, and measurement conditions for obtaining measurement data that will be inputted into the model;

A soil measurement assisting method for a soil measuring apparatus that measures properties of a soil, comprising the steps of:

• acquiring a first set of measurement data related to optical properties of a measurement site;
• determining a preliminary soil model based on the acquired first set of measurement data and information stored in a storage means on the soil measuring apparatus;
• reading out the preliminary soil model;
• acquiring a second set of measurement data related to chemical components of the soil;
• and
• modifying the preliminary model based on the second set of measurement data.

A recording medium that can be read by a computer and that stores a soil measurement assisting program that includes commands for the computer to execute:

• a process that acquires initial measurement data related to a soil type and a water content of a soil of a measurement site;
• a process that, based on the acquired initial measurement data, accesses a storage region that stores information related to the soil type, the information related to the water content of the soil, a model for calculating soil properties, and measurement conditions for acquiring further measurement data to be inputted into the model;
• and
• a process that outputs a set of suitable measurement conditions and the model determined based on the initial measurement data related to the soil type and the water content.
