ANATOMY OF A SOIL REPORT
You don’t need a PHD to under stand pH.
We are committed to making your soil results make sense to you.
Use our interactive tool below to learn more about how to read your soil report, and please call us with any questions.
Click the boxes below to see more info that will help you better understand the elements of your soil report.
The balance between acidity and alkalinity. A pH of 7.0 is neutral, optimal is 6.0-7.0.
Electrical Conductivity: A measure of soil salts. An important measure of total soil health. Maintain levels from 1.0 – 2.5.
Calcium. Essential for cell wall structure and total plant strength. Counteracts negative effects of soils salts.
Magnesium. Essential for photosynthesis and is part of the chlorophyll in green plants.
Sodium. A potentially toxic element that can greatly reduce plant vigor. Sodium can easily be displaced with gypsum application.
Chloride. High concentrations are toxic to most plants, particularly woody species.
Sulfate Sulfur is essential for several growth functions, including nutrient uptake, chlorophyll production, seed development and root strength, and stress and pest resistance. Gypsum is a great source of pH neutral SO4.
Sodium Absorption Ratio. An expression of the relative activity of sodium.
Boron. Regulates the uptake of other nutrients. Essential for seed and fruit development. The range between sufficiency and toxicity is very small. Always use lab analytics for applications.
Saturation Percentage. Measures the heaviness of soil. Sand will have lower values (20-25), Clay will have higher values (45+).
Exchangeable Cations (ppm)
Ions held on the soil that can be replaced by other ions of like charge. See recommended results on lab analysis.
Base Saturation (%)
This is the percentage of the Cation Exchange Capacity occupied by the basic cations Ca2+, Mg2+ and K+.
Total Electrical Conductivity. Measures the soil’s ability to exchange nutrients. Lower values (0-10) express a soil with marginal ability to hold nutrients and water. Can be relative to a soils particular environment.
Less than 2%
Other Bases (%)
Responsible for protein synthesis.
Aids rapid growth. Increases seed and fruit production.
Essential part of photosynthesis. Encourages bloom and root development.
Essential for the transformation of carbohydrates. Regulates consumption of sugars.
Necessary for the formation of chlorophyll.
Important for reproductive growth.
Responsible for the breakdown of carbohydrates and nitrogen metabolism.
Organic Matter (%)
Should be maintained at 1.0% or higher.
Illustrates ability to alter soil pH and nutrient ability. Avoid acidification if lime is low or not present.
Bicarbonate -Aids in pH buffering
Naturally occurring beneficial proteo bacteria which is an effective soil inoculant.
Regular use of gypsum is essential to sustainability of most irrigated soils. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils.
