Step 2: Start With Healthy Soil 


Understand the chemical, physical, and biological properties of the soil in your Jersey-Friendly Schoolyard. Learn about best practices for achieving and maintaining healthy and sustainable soil to support your garden or landscape, as well as protect water quality, water supplies, and living resources in your local community. 

Why It’s Important

Healthy soil is at the root of all life on Earth. A foundation of healthy soil is essential for a successful Jersey-Friendly garden. Healthy soil is an optimal balance of physical, chemical, and biological components that provide the right amount of air, water, and organic matter for microorganisms to thrive and for plants to grow. 

Soil provides important ecological functions. It absorbs, filters, cleans, and stores groundwater, and channels it throughout the landscape, creating rivers, ponds, and estuaries. Soil stores nutrients and moderates the release and cycling of elements such as nitrogen, phosphorus, and potassium. Soil stores carbon, keeping it out of the atmosphere. 

Visit Step 2: Start With Healthy Soil on the Jersey-Friendly Yards website to learn more about soil and how to take a soil sample, and for additional tips, tools, and resources to create a healthy foundation for your Jersey-Friendly garden.

Standard Actions

Give your soil a check-up! Provide lessons to your students that explore soil properties and help you assess the health of your soil. 

2A: Explore the PHYSICAL properties of soil.

Test the physical properties of the soil in your schoolyard, including texture and soil moisture.

Soil Texture
Different plant species require different soil textures in which to grow. Determine the texture of your soil by conducting a ribbon test or jar test with your students. The soil texture pyramid and soil calculator will help determine the quantities of sand, silt, and clay in your soil sample, guiding you towards your soil’s texture type. Or you can collect a soil sample and send it to Rutgers Soil Testing Lab for analysis.

  • Clay is fine-textured soil.
  • Silt is medium-textured soil. 
  • Sand is course-textured soil.
  • Loam is a mix of sand, silt, and clay. 
  • Organic soil contains a high percentage of organic matter, such as decaying leaves.

Soil Moisture
Soil moisture is a physical property of soil. Different soil types can hold various amounts of water; this is called soil moisture. The amount of water that plants need to survive is stored in the soil. Different plant species require different amounts of water. Knowing the amount of moisture your soil holds will guide your selection of plants that prefer either dry, moist, or wet soil conditions. Use the definitions below to determine the overall soil moisture of your garden. You and your students can also assess the soil moisture content by appearance and feel

  • Dry soil: water does not remain on the ground after a rain.
  • Moist soil: soil is damp, and occasionally saturated. 
  • Wet soil: soil is saturated, except during drought.

2B: Explore the CHEMICAL properties of soil.

Test the chemical properties of the soil in your Jersey-Friendly Schoolyard, including the pH and nutrient levels

Soil pH
Determine your schoolyard soil’s pH, which is a chemical property of soil. It is the measurement of the acidity or alkalinity of the soil. The pH scale ranges from 0 to 14. A pH of 7 is neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. Soil pH is important because it affects the availability of nutrients to the plants and the activity of soil microorganisms beneficial to plants.  

Each plant species requires a certain soil pH in which to grow. Knowing the pH of the soil in your garden will guide your selection of plants that require either acidic, slightly acidic, neutral, alkaline, or very alkaline soil. Determine the pH of your soil by conducting a pH test with your students, or collect a soil sample and send it to Rutgers Soil Testing Lab. Conduct the tests using soil collected in the area where you plan to install your Schoolyard garden. 

  • Acidic soil is 6.0 and lower on the pH scale.
  • Slightly acidic soil is between 6.1 – 6.5 on the pH scale. 
  • Neutral soil is between 6.6 – 7.3 on the pH scale.
  • Slightly alkaline soil is 7.4 – 7.8 on the pH scale. 
  • Alkaline soil is 7.9 and higher on the pH scale.

Soil Nutrients
Plants derive their nutrients from the soil. The three macronutrients needed by all plants are nitrogen (N), phosphorus (P) and potassium (K). Since excessive amounts of nutrients can harm plants, it’s important to get the soil tested to determine need before applying anything. To determine the types and quantities of nutrients in your schoolyard soil, you can send a soil sample to Rutgers Soil Testing Lab for analysis, or you and your students can test the soil for NPK using a classroom kit such as RapiTest.

2C: Explore the BIOLOGICAL properties of soil.

Healthy soil is full of life! Soil provides habitat for millions of organisms, hard at work under your feet. These underground organisms transfer energy to plants through their roots. Plants are primary producers which supply the energy to keep the above-ground food web cycling. Provide lessons to your students that introduce them to the soil food web and how these organisms keep soil and plants healthy
