What are the advantages of low biuret urea?

When high doses of nitrogen have to be given via leaves especially in certain seasons, nitrogen to be provided has to have organic origins with no toxic side effects. Most feasible source of nitrogen is therefore urea. Biuret is a toxic side product of the production process of urea fertilizers. The biuret content of ordinary urea fertilizers that are utilized as subsoil fertilizers is around 1-2%. When such an ordinary urea fertilizer is given via leaves, phytotoxicity occurs in plants. If low doses are used, then high nitrogen needs of plants are not met. As a result when we have to apply urea fertilizers via leaves, or when high and fast doses of nitrogen have to be applied, biuret content in such urea fertilizers has to be low. Nitrogen composition in low biuret urea fertilizers are organic amines. This is a leaf fertilizer that can be easily applied to plants, which are sensitive to biuret.
