Concentrations of Nitrogen in Plants - Biocyclopedia

Ratios of Concentrations of Nitrogen to Other Nutrients in Plants The critical concentration of nitrogen is the value in a particular plant part sampled at a given growth stage below which plant growth and yield are suppressed by 5 or 10% .The responses of plants to nutrient additions are essentially independent of the source of nutrients; hence, the symptoms and nutrient

Nutrients, even though one or more may be deficient, are usually more concentrated in stunted plants. For example, the concentration of nitrogen may be greater in plants that are 12 inches in height compared to plants that are much taller. The nitrogen is simply diluted by carbohydrates in plants that are much taller.

Nutrient Acquisition by Plants Organismal Biology

While plants have ready access to carbon (carbon dioxide) and water (except in dry climates or during drought), they msut extract minerals and ions from the soil. Often nitrogen is most limiting for plant growth; while it comprises approximately 80% of the atmosphere, gaseous nitrogen is chemically stable and not biologically available to plants.

Elevated CO 2 and plant nitrogen-use: is reduced tissue ...

Plants often respond to elevated atmospheric CO2 levels with reduced tissue nitrogen concentrations relative to ambient CO2-grown plants when comparisons are made at a common time. Another common response to enriched CO2 atmospheres is an acceleration in plant growth rates. Because plant nitrogen concentrations are often highest in seedlings and subsequently

Refractory Nitrogen is the nitrogen that can’t be biologically decomposed. Alkalinity is easiest defined as the ability to resist a drop in pH. This is very important because for every 1 part ammonia (NH3) converted to nitrate (NO3) – 7.1 parts of alkalinity are depleted, and for every 1 part nitrate (NO3) removed – 3.6 parts alkalinity ...
