Description
Organic matter is decomposing or decomposed materials from plants and animals, and it is an essential component of a healthy soil. High organic matter contents lead to improved soil tilth (workability), water retention, soil structure, and nutrient retention. Representative organic matter percentages compiled from the SSURGO database were used to estimate organic matter content for all soil series (Low = 0-3, Moderate = 4-10, High = 11-20, and Very High > 20%).
