Urea Fertilizer: Guide

Risso Chemical has 3 advanced technology production lines for urea fertilizer, NPK compound fertilizer, BB fertilizer automatic production line and 1 multi-functional laboratory with annual production capacity of 600,000 tons. Urea is mainly used as a nitrogen-rich fertilizer in agriculture. It is considered one of the most popular and economical sources of nitrogen for plants. Urea helps to promote healthy plant growth, increase crop yields and improve crop protein content. It is commonly used to provide plants with nitrogen that is readily available and easily absorbed. Urea is soluble in water and is used as a neutral, quick-release, highly concentrated nitrogen fertilizer. It is prone to moisture absorption and caking in air. Urea is widely used as a basic raw material for NPK compound fertilizer, BB fertilizer , and can also be coated with sulfur or polymers as a slow-release or controlled-release fertilizer. Long-term application of urea will not leave any harmful substances on the soil.
