A Pasture Soil test measures:

• pH – measures the acidity or alkalinity of the soil which affects the availability of nutrients to plants.
• Phosphorous (Olsen P) – assesses the availability of Phosphorous to plants, important for energy transfer n plants supporting plant growth and health.
• Cations (Calcium, Potassium, Magnesium and Sodium) – measures the extractable amount of cations, key nutrients essential for plant growth.
• Cation Exchange Capacity (CEC) – the higher the CEC the greater the capacity of soil to store and retain cations (Ca, Mg, K, Na).
• Base Saturation – provides a percentage saturation of the CEC for each of the cations and can be used to better understand and plan your fertiliser needs.
• Volume weight – the density of a known volume of air-dried and ground soil - gives an indication of the soil’s physical character (e.g. sandy soils vs clay vs pumice vs peat, etc).
• Sulphate Sulphur (SO42-) – provides the extractable amount of Sulphate Sulphur - a building block for plant protein.
• Extractable organic Sulphur – provides the extractable sulphur content in the organic matter which is an indicator of sulphur reserves in the soil.
