Urea as a fertilizer is an organic molecule produced by combining 2-NH3 and 1-CO2. The product of this reaction is combined with ammonium nitrate to form Liquid Nitrogen (UAN) (32-0-0) or cooled and granulated for dry fertilizer containing 46% Nitrogen (N). Urea is the most used fertilizer in the world and an excellent source of Nitrogen. Urea is produced throughout the world wherever natural gas is sourced and ammonia made. Nitrogen, regardless of its form, is a profitable investment.
Dry urea has the highest N content of the dry fertilizers (46%), is stable in storage, transportation, and blending. It is water soluble and 100% available. Once applied to the soil urea ionizes in to 2-NH4 & 1-CO2 Nitrogen is necessary for plant growth and is involved in virtually every cell function. Nitrogen and Sulfur form the backbone of amino acids and proteins within all cells of both plants and animals.
1. High nitrogen content
2. Easily transported and handled
3. Ionizes into NH4 in the soil.
4. Can be blended with Sulfur fertilizers to make an excellent growth promoting fertilizer
1. Subject to volatilization on dry, calcareous, and/or high pH soils
(However, can be treated with stabilizers to reduce volatilization or tilled or watered in)
2. High price fluctuations due to the commodity nature of this compound.
Sometimes agricultural fertilizer must compete with industrial users for urea. (Feed, resins, insulation, and cosmetics)
3. Can be hydroscopic in moist climates.
4. Care must be taken when applying with or near seed.
