Particle density

Particle density is the volumetric mass of the solid soil. It differs from bulk density because the volume used does not include pore spaces. Particle density depends on the chemical composition and crystal structure of solid mineral particles and is not affected by pore space.

  • Total core water holding %

    This is a measure of the water holding capacity of your soil sample. It is a very important agronomic characteristic of soil. Lower water holding capacities reach saturation sooner than soils with higher water holding capacities and are subject to leaching losses of nutrients and pesticides.

  • Uniform wetting %

    This is a measure of a mass of water that is retained in a mass of disturbed, oven-dried soil. For example, if water holding is 62%, this means the weight of the dry soil increased by 62% and released the rest of the testing water quantity used. The purpose of this test is to indicate if any 1 inch (2.5cm) sections of the sample are the same, or higher, or lower in comparison with each other in order to see how uniform the soil is wetting.
