Particle Size Distribution (PSD)
We offer precise particle size distribution analysis across various fraction sizes to help you understand the texture and composition of your soil samples.
Fraction Sizes: 80mm, 40mm, 20mm, 10mm, 4.75mm, 2mm, 1mm, 600μm, 425μm, 212μm, 150μm, 75μm
Clay and Silt Fractions (Hydrometer Method): Our hydrometer analysis provides accurate measurements of the clay and silt fractions in soil, informing soil texture classification and management practices.
PSD Semi-log Graphs: Utilizing years of particle size distribution data, we generate detailed semi-logarithmic graphs. These graphs provide a comprehensive analysis by deriving critical parameters from the PSD data, offering valuable insights into soil characteristics.
Water Content Analysis
Field Capacity (FC): We measure the field capacity of soil, indicating the amount of water retained after excess water has drained away and the rate of downward movement has decreased.
Plant Available Water (PAW): Our analysis determines the amount of water available for plant uptake between the field capacity and the permanent wilting point.
Saturated Moisture Content: We measure the maximum amount of water that soil can hold when completely saturated, providing critical data for irrigation and drainage planning.
Rockwater Absorption: We assess the soil’s rockwater absorption capacity to understand its drainage properties and suitability for various land uses.
pH Analysis
pH (H2O): We measure the soil pH in a 1:2.5 water solution to determine its acidity or alkalinity (or any other solution ratio required).
pH (KCl): We also measure soil pH in a potassium chloride solution for a more buffered reading of soil acidity.
Oxidation-Reduction Potential (ORP)
Our ORP testing indicates the soil’s ability to oxidize or reduce, which is crucial for understanding soil chemical reactivity and geochemical equilibrium.
Electrical Conductivity (EC): We measure the electrical conductivity of soil in a saturated paste (or any other solution as required), providing an indication of the soil's salinity levels.
Total Dissolved Solids (TDS): Our TDS measurement determines the concentration of dissolved salts in the soil, which can affect plant growth, soil structure, and soil-microbe sensitivity.
Linear Shrinkage: We measure the linear shrinkage of soil, which is essential for predicting soil behavior under varying moisture conditions.
Soil and Aggregate Stability
Aggregate Stability: We evaluate the stability of soil aggregates, which is crucial for understanding soil erosion potential and structural integrity.
Slaking: Our soil and rock slaking test assesses the tendency of soil aggregates and different rock types to break down when wetted, indicating stability and erosion risk.
