Common Soil Amendments

Soil amendments are materials that are added to soil to improve its physical properties, such as water retention, permeability, water infiltration, drainage, aeration and structure. The goal is to provide a better environment for roots. These materials include:

  • Lime – raises soil pH, reduces acidity
  • Sulfur – lowers soil pH, increases acidity
  • Gypsum – improves aeration of compacted soil, improving drainage
  • Biochar – increases the fertility of acidic soils and protects against some soil-borne diseases
  • Humic acid – transports water and nutrients from the soil to the plant, preventing them from leaching away
  • Fulvic acid – improves the uptake of minerals and stimulates plant growth
  • Compost – decomposed organic matter that improves aeration and moisture retention and enriches the soil
  • Bone meal – adds phosphorus and calcium to the soil; can be harmful to pets
  • Blood meal – increases acidity and adds nitrogen back to the soil very efficiently

Try Mag-I-Cal® Plus

Use a Soil pH Test Kit for Lawns to check the pH of your soil.  You can buy one at your local hardware store or garden center or at JonathanGreen.com.

The pH level of the soil is vital to growing lush, green lawns. On a scale of 1 to 14, a pH of 1 is very acidic, a pH of 14 is very alkaline, and a pH reading of 7 is neutral.  Lawns grow best in soil that is slightly acidic to neutral (between 6.2 and a 7.0 on the pH scale), and a balanced pH will increase microbial activity in the soil.

Jonathan Green Mag-I-Cal® Plus is a unique soil food that combines Mag-I-Cal® and Love Your Soil®. It rapidly adjusts soil pH, loosens hard soil, and activates microbes to create a biologically healthy soil. 

If your soil’s pH is too low, treat it with Mag-I-Cal® Plus for Lawns in Acidic & Hard Soil. Our innovative formula will quickly raise the soil pH and feed soil microbes with humates to help the lawn grow greener and healthier. It can be applied the same day as the grass seed is spread.

When soil pH is too high, Jonathan Green’s Mag-I-Cal® Plus for Lawns in Alkaline & Hard Soil which contains sulfur and calcium sulfate dihydrate will lower the pH, improve root penetration, and promote growth. It can be applied the same day as the grass seed is spread.
