Our soil tests
Comprehensive suite of tests that provide a holistic assessment of your sample.
Pasture soil analysis
Soil Fertility suite for pasture including key nutrients and sulphate analysis
Extra tests
Additional tests that can be added to a soil analysis for more detailed insights.
Mineral N (Deep Nitrogen Test) Analysis
Mineral N (Deep Nitrogen Test) Analysis
Mineral N Analysis for immediately available Nitrogen
Measures: Ammoniacal-N and Nitrate-N
When to test: Pre-plant and/or just before side dress N is applied.
Potentially Mineralisable Nitrogen (PMN)
Potentially Mineralisable Nitrogen (PMN)
Smart Sustainability through PMN Testing! Cost-Efficiency for Nitrogen Management
Measures: Nitrogen potentially released from organic matter over a period of time during crop growth
When to test: On cropping soils before planting.
Anion Storage Capacity (P Retention)
Anion Storage Capacity (P Retention)
Find out how well your soil holds key nutrients like phosphorus and sulphur.
Measures: Measures the ability of the soil to store anions like phosphate and sulphate.
When to test: Initial test to establish value for soil type.
Reserve Potassium (TBK)
Reserve Potassium (TBK)
Tap into the ability of some soils to release potassium over time
Measures: Potassium captured within the clay structures of the soil that is not extracted by the conventional quick soil test. It is the fraction of potassium that is slower to become plant available
When to test: As an extra test during routine soil testing on sedimentary and recent soils.
Anaerobically Mineralisable Nitrogen (AMN)
Anaerobically Mineralisable Nitrogen (AMN)
Provides insights into soil nitrogen availability
Measures: Potentially available nitrogen through anaerobic soil incubation
When to test: Pre-plant.
Organic Matter
Organic Matter
Monitor carbon sequestration
Measures: Organic matter content is calculated by multiplying total carbon by 1.72
When to test: As an extra test during routine soil testing.
Exchangeable Aluminium
Exchangeable Aluminium
Confirm aluminium toxicity that can negatively affect plant growth
Measures: Aluminium extractable with an dilute calcium chloride solution
When to test: Only when the pH is below 5.5
Hot Water Soluble Boron
Hot Water Soluble Boron
Master Soil Nutrients with Boron Testing. Vital for Growth
Measures: Soil boron
When to test: During routine soil testing for boron sensitive crops, mainly high value horticultural crops.
Trace Element Testing (EDTA)
Trace Element Testing (EDTA)
Measure key elements essential for Thriving Crops
Measures: Fe, Mn, Cu, Zn, Co
When to test: During routine soil testing and when micro-nutrient deficiency symptoms in crops are observed, typical chlorosis of leaves.
Resin Phosphorus
Resin Phosphorus
Soil Potential with Resin Phosphorus Testing
Measures: Phosphate in soil solution especially applicable to limed soils and RPR treated soils
When to test: During routine soil tests.
Total Carbon and Nitrogen
Total Carbon and Nitrogen
Evaluate Total Carbon & Nitrogen! Gauge to important factors of Soil Health for Sustainability
Measures: Total carbon, Total Nitrogen. Organic Matter content and C/N ratio are calculated from these measures
When to test: During routine soil testing.
EPA Heavy Metals
EPA Heavy Metals
Ensure Environmental Compliance through EPA Metals Testing. Meet Standards
Measures: As, Cd, Cr, Cu, Pb, Hg, Ni, Zn
When to test: When land is sold or where there is a change of use, or when contamination is expected.
Hot Water Extractable Carbon
Hot Water Extractable Carbon
Track subtle changes in soil quality based on labile carbon compounds.
Measures: Easily extractable soluble carbon compounds.
When to test: Every 2-3 years.
