ROOT SURFACE [2 records]

Record 1 2007-08-29

English

Subject field(s)
  • Plant Biology
CONT

Nutrient uptake by crops depends on nutrient supply in the soil, root surface area, and root activity. Roots are able to absorb only the nutrients that come into contact with living and active cells, so P uptake is dependent on the condition of a plant's root system. Nutrients contact the root surface by three mechanisms: diffusion, mass/bulk flow, and root interception.
