Soil Testing

Soil and Organic Certification Tests

Using the latest technology, Hill Labs offers a complete range of soil tests for evaluating fertility and soil health, as well as tests to meet organic certification requirements.

Hill Labs soil testing services allow measurement of the nutrient status of soil for a whole range of land-use purposes. Understanding the soil nutrient status is important regardless of whether you are a large-scale farming or horticultural operator, recreational turf or garden manager, or small lifestyle block owner. Our soil tests enable you to make sound management decisions for sustainable land use. We also have tests that are required to meet organic certification, as well as environmental soil tests to assess potential contamination.
