Solution investigated: Effect on soil structure

Soil structure : 

• Sandy clay loam texture
• Clay (26 %)
• Silt (44 %)
• Sand (30 %)

Main results: 

• Increased soil porosity at the macroscopic and microscopic scale
• The improvement in soil micro porosity explains an increased water retention and
  availability in the root zone
• The improvement in macro soil porosity explains an increased drainage of water
