Plant nutrition Wikipedia
Nitrogen is a major constituent of several of the most important plant substances. For example, nitrogen compounds comprise 40% to 50% of the dry matter of protoplasm, and it is a constituent of amino acids, the building blocks of proteins. It is also an essential constituent of chlorophyll. Nitrogen deficiency most often results in stunted growth, slow growth, and chlorosis.

Concentrations of Nitrogen in Plants .
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 concentrations of ...

A Simple Model for Nitrogenlimited Plant .
INTRODUCTION. In many studies of nitrogenlimited plant growth, a linear relationship has been found between relative growth rate and plant nitrogen concentration, showing a negative intercept at a plant nitrogen concentration of zero ( Ingestad, 1979; Ingestad and Ågren, 1992).This equation forms the basis of the nitrogen productivity theory (Ågren, 1985, 1988, 1994).

Plant nitrogen uptake and assimilation: .
Introduction. Nitrogen (N) is required for plants to complete their life cycles and is the most important nutrient acquired in greatest quantities by roots (Xu et al., 2012; Oosterhuis et al., 2014).NO 3 – and NH 4 + are the most prominent forms of inorganic N taken up by land plant species, and their root uptake rapidly causes primary effects on ionic and pH balance in plant cells.

Nitrogen is part of the chlorophyll molecule, which gives plants their green color and is involved in creating food for the plant through photosynthesis. Lack of nitrogen shows up as general yellowing (chlorosis) of the plant. Because nitrogen can move around in the plant, older growth often yellows more than the new growth.
