Fertilizers

Fertilizers are a large number of organic and synthetic materials, spread on or worked into soil to increase its capacity to support plant growth. Fertilizers are divided into two broad groups: organic and inorganic, or chemical. Organic fertilizers are derived from living plants or animal sources. Chemical fertilizers are usually manufactured and have the advantage of low cost. The commonly used synthetic fertilizers consist almost entirely of nitrogen, potassium and phosphorus in forms that are readily utilized by plants.

Product Description:

Liquid ammonia is the best-known and most widely studied nonaqueous ionizing solvent. Its most conspicuous property is its ability to dissolve alkali metals to form highly colored, electrically conducting solutions containing solvated electrons.

Product Application:

Apart from these remarkable solutions, much of the chemistry in liquid ammonia can be classified by analogy with related reactions in aqueous solutions. Comparison of the physical properties of NH3 with those of water shows that NH3 has the lower melting point, boiling point, density, viscosity, dielectric constant and electrical conductivity. These properties are due at least in part to the weaker hydrogen bonding in NH3 and the fact that such bonding cannot form cross-linked networks in the way water molecules do.

Product Description:

Product Application:

A pale yellow nonmetallic element occurring widely in nature in several free, allotropic and crystal forms and combined in numerous sulfates and sulfides. It is used in black gunpowder, rubber vulcanization, the manufacture of insecticides and pharmaceuticals, and in the preparation of sulfur compounds such as hydrogen sulfide and sulfuric acid. Atomic number 16; atomic weight 32.066; melting point 115.21°C; boiling point 444.61°C; specific gravity at 20°C (rhombic) 2.07, (monoclinic) 2.00; valence 2, 4, 6.

Product Description:

Urea, a white crystalline solid containing 46% nitrogen, is widely used in the agricultural industry as an animal feed additive and fertilizer Here we discuss it only as a nitrogen fertilizer.

Product Application:

Urea can be readily nitrified – that is, converted to nitrate (NO3) – even when applied late in the fall, and can be quite susceptible to denitrification or leaching the following spring. Anhydrous ammonia (AA) applied in the fall does not nitrify as quickly, due to the stunting of microorganisms in the AA application band.
