1. A soil analysis device comprising:

  • a mixing chamber receiving a soil sample and an extractant, the mixing chamber producing a liquid mixture by mixing the soil sample and extractant;

    a filtration system coupled to the mixing chamber and receiving the liquid mixture from the mixing chamber, the filtration system filtering the received liquid mixture; and

    a measurement cell coupled to the filtration system and receiving the filtered liquid mixture, the measurement cell coupled to a light source so that light propagating from the light source is attenuated by the filtered liquid mixture and is measured by an optical detector coupled to the measurement cell, the optical detector generating an attenuation spectrum indicating light received by the detector at different wavelengths.
