Of all the essential nutrients, nitrogen is required by plants in the largest quantity and is most frequently the limiting factor in crop productivity. 1  In plant tissue, the nitrogen content ranges from 1 and 6%.
Limiting factors may be biotic, such as the availability of food, or abiotic, such as access to water. Human infl uences oft en act as limiting. factors. infl uence of abiotic Factors. Abiotic factors such as temperature, light, and soil can infl uence a speciesâ. ability to survive. Every species is able to survive within a range of each of. these factors. Th is range is called the speciesâ tolerance range (Figure 1).
