- Title
Steep, cheap and deep: an ideotype to optimize water and N acquisition by maize root systems.
- Authors
Lynch, Jonathan P.
- Abstract
Background A hypothetical ideotype is presented to optimize water and N acquisition by maize root systems. The overall premise is that soil resource acquisition is optimized by the coincidence of root foraging and resource availability in time and space. Since water and nitrate enter deeper soil strata over time and are initially depleted in surface soil strata, root systems with rapid exploitation of deep soil would optimize water and N capture in most maize production environments.
