Definitions for "Limiting Nutrient"
The nutrient in shortest supply in a particular ecosystem.
A nutrient not present in the soil in sufficient quantity to support optimal plant growth.
The nutrient that is in lowest supply relative to the demand. The limiting nutrient will be exhausted first by algae which require many nutrients and light to grow. Inputs of the limiting nutrient will result in increased algal production, but as soon as the limiting nutrient is exhausted, growth stops. Phytoplankton growth in lake waters of temperate lowland areas is generally phosphorus limited.
