Everything for soil measurements and analysis

A small sample of soil can provide a wealth of information. With the right equipment, you could analyse the structure and texture of soil, which determines its permeability, ease of tillage, sensitivity to erosion and more. Soil stability is essential for agriculture and a pF-curve tells you all about a soil's moisture contents.

The properties of soil, which you can find through soil testing, are helpful indications for effective agriculture, construction, engineering and even archaeology. Find the right analysis method for your situation below.

pF determination

pF determination is essential when researching the accessibility of water in the soil for plants and trees. Soil moisture measurements provide valuable insights for agriculture, but engineering as well.

Particle size distribution

Particle size distribution is one of the most important characteristics of soil. Soil texture in great part determines how suitable it is for its intended use, such as agriculture. It affects the ease of tillage, capillary conductivity, available moisture, permeability, compaction and more.

Aggregate stability

Aggregate stability determines how resistant or sensitive a soil structure is to destructive forces and erosion. Soil structure is one of the main factors that control plant growth, because it influences the root penetration, soil temperature and gas diffusion, water transport, and seedling emergence. It is, therefore, an important soil characteristic for farmers.

Soil volume and density

The ratio of solid mass, water and air in soil is important to determine for both forestry and agriculture, as well as soil and water management studies. Soil moisture and porosity, which affects how suitable the soil is for its intended use, is in large part influenced by the ratio of all different components of the soil.

Air permeability apparatus

Air permeability

Soil air permeability is one of the most important parameters for the aeration in agricultural soils. Both air and water are essential for plant growth, and air permeability determines in large part how much oxygen the plant roots have access to. Royal Eijkelkamp offers instruments to measure air permeability in the field and in the laboratory.

Water permeability

Determination of water permeability, or hydraulic conductivity, is important for agricultural as well as for environmental soil research. The permeability factor, or K-factor, serves as an indication to base the designs of irrigation- and drainage systems on. It's also of great importance with respect to the extent of the spreading of possible pollution.

Compression and shear testing

Compression and shear stress tests measure a soil’s resistance to deformation when it’s submitted to shear or compression. Altered soil functions, especially the reduced hydraulic conductivities and impeded aeration, could decrease crop growth and productivity as well as the filtering and buffering capacity of soils. Testing shear and compression strength offers valuable insight for soil use.

Calcium carbonate content

The calcium carbonate content indicates how alkaline or acid the soil is. This determines in large part the quality of the soil, and its fertility. To determine the carbonate content, Royal Eijkelkamp offers a calcimeter that works in accordance with the method of Scheibler. It was developed together with Dutch research institutes and meets the standards of NEN 5757 and DIN 19682 and 19684.
