Methods of analyzing one or more agricultural materials, and systems thereof

A system for analyzing one or more agricultural materials comprising:

• a chamber receiving an agricultural material, the agricultural material comprising a solid;
• the chamber comprising a mixing device configured to mix the solid with a liquid to form a slurry;
• and a measurement device configured to measure electrical conductivity of the solid within the slurry, the electrical conductivity of the solid being used to determine a characteristic relating to the solid within the slurry, wherein the measurement device is a particle density measurement device configured to measure a density of the solid in the slurry via the electrical conductivity measurement wherein the solid is a soil sample and the liquid is water which defines a soil slurry:
• wherein at least one of a plurality of electrodes is placed on opposing sides of a flow of the slurry in spaced relationship within a flow conduit, each of the at least one of the plurality of electrodes being configured to measure electrical conductivity in contact with a respective side of the flow of the slurry:
• and wherein the flow conduit and chamber are integral fluidic parts of a closed slurry recirculation flow loop which comprises a recirculation pump configured to circulate the slurry through the flow conduit and chamber.
