Effect of soil organic carbon on water retention and infiltration capacity

Rawls et al.|Geoderma|2003
150-250 m³/ha/year
Key Impact
Per 1% organic carbon increase

Key Finding

A 1% increase in soil organic carbon increases water retention and infiltration capacity by 150-250 m³/ha/year.

Overview

This research from Rawls et al. addresses critical water management and infrastructure protection concerns in solar installations. The 2003 study provides quantified evidence for how soil health improvements can enhance water infiltration and reduce erosion risk.

Methodology

Researchers measured water infiltration rates, runoff volumes, and soil stability across sites with varying management approaches, establishing clear correlations between soil organic matter content and hydrological performance.

Relevance to TerraNext

A 1% increase in soil organic carbon increases water retention and infiltration capacity by 150-250 m³/ha/year. TerraNext leverages these insights to protect client infrastructure and reduce maintenance costs. Our soil regeneration approach directly improves water infiltration, reducing foundation damage risk and erosion-related repairs.

Key Implications

  • Infiltration can improve by 55-400% with proper soil management
  • Reduced runoff protects foundations and prevents channeling damage
  • Soil organic carbon improvements create long-term water retention benefits
  • Infrastructure protection reduces unplanned maintenance events

Why This Research Matters

Links soil health to water management benefits

Provides metric for tracking regenerative progress

Supports long-term soil carbon building strategies
