A soil test is a comprehensive analysis to assess the chemical, physical, and biological properties of soil. This examination provides detailed insights into the soil’s fertility, nutrient content, organic matter composition, pH levels, and the presence of contaminants or deficiencies. Soil samples are collected from various areas and sent to a laboratory for analysis. The results help optimise soil health and productivity.
1. Soil Fertility Assessment
Soil samples evaluate essential nutrients like nitrogen, phosphorus, potassium, and micronutrients. Assessing soil fertility allows targeted fertiliser application to address deficiencies, improving productivity.
2. pH Analysis
Testing soil pH determines if the soil is acidic, neutral, or alkaline. Adjusting pH enhances nutrient availability and microbial activity, promoting healthier plant growth.
3. Soil Composition and Texture
Soil samples reveal the composition and texture of the soil, aiding in understanding soil structure, water-holding capacity, and drainage. Analysing these parameters allows for proper soil amendments to create an ideal growing environment.
4. Contaminant Identification
Soil sampling identifies potential contaminants, including heavy metals, pesticides, and pollutants. Regular soil testing helps detect and mitigate contamination, ensuring safe food production and land use.
5. Soil Health Assessment
Soil health refers to the soil’s capacity to function as a living ecosystem. Soil sampling evaluates indicators like organic matter content, microbial activity, and soil structure. Assessing soil health promotes sustainable land management practices and conserves soil resources.
1. Nutrient Levels
Determining the concentrations of essential nutrients in the soil helps assess soil fertility. Key nutrients to evaluate include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and micronutrients like iron (Fe), zinc (Zn), and manganese (Mn).
2. Soil pH
Measuring soil pH provides insights into the soil’s acidity or alkalinity, which affects nutrient availability and microbial activity. The optimal pH range varies for different plants, but generally falls between 6 and 7.
3. Organic Matter Content
Organic matter plays a vital role in soil fertility, water holding capacity, and soil structure. It is assessed by determining the percentage of organic carbon present in the soil.
4. Soil Texture
Soil texture refers to the proportion of sand, silt, and clay particles in the soil. It affects drainage, water retention, and nutrient availability. Soil texture can be determined through laboratory analysis or by using simple field tests.
5. Contaminant Levels
Soil samples should be tested for the presence of contaminants such as heavy metals, pesticides, and pollutants. Elevated levels of these substances can have detrimental effects on plants, animals, and humans.
1. Interpret the results correctly
Once you have your soil test results, it is important to interpret them correctly. Baileys provides you with a report with a summary of the various nutrient deficiencies that need to be corrected.
2. Take action based on the results
Once you know the results of your soil test, you need to take action. Baileys will create a fertiliser program for you that will help towards producing healthy sustainable soil while supplying all the necessary nutrients for plant growth.

When Perth-based contractor Luke, owner of Silverstone Gardening and host of the Australian Lawn & Garden Podcast, invited Baileys Shannon White onto the show, the goal was simple: share practical fertiliser knowledge that can help turf managers achieve better results and build more profitable businesses.
A fantastic day of learning, collaboration, and practical demonstrations — bringing together industry experts to share real-world experience and innovative approaches to managing sports turf.
Baileys are thrilled to learn about the Urban Greening Grant Program, a collaborative effort between the Department of Water and Environmental Regulation (DWER) and WALGA.
