Nutrient Content of Plants: UGA AESL

A plant analysis interpretation is based on a comparison of the nutrient concentration found in a particular plant part taken at a specific time with known desired value or ranges in concentration. One method of interpretation is based on "critical values," a critical value being the concentration below which deficiency is likely to occur.

Diagnosis of Nutrient Status. Most designs for using plant analysis to assess nutrient status are based on the relationship between nutrient concentration and yield or growth of a plant or plant part. There are different ways to express concentration, but the most common are percent (%) and mg/kg (or part per million, or ppm).

Targeting Root Ion Uptake Kinetics to Increase Plant

Depriving a plant of a focal nutrient and then exposing it to a high nutrient concentration for a period of time has been widely reported to substantially increase plant influx rates. For example, nitrate influx rates were shown to be significantly greater in N-starved plants compared to replete plants ( Siddiqi et al., 1990 ; Raman et al., 1995 ).

Water potential plays a key role in a plant's nutrient uptake. If the water potential is more negative within the plant than the surrounding soils, the nutrients will move from the region of higher solute concentration—in the soil—to the area of lower solute concentration in the plant.
