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%.
Nitrogen is the one nutrient most often limiting plant growth. The need for nitrogen varies from plant to plant. For example, tomatoes and vine crops (cucumbers, squash, and melons) will put on excessive vine growth at the expense of fruiting with excess nitrogen.enefits of organic fertilizers and soil amendments include improvements in soil tilth (suitability of the soil to support plant growth). This should not be confused with âfertilizationâ, a distinctly different soil management objective. Organic soil amendments are typically low in nutrient content.
