WebCo-crystal urea will be evaluated based on total biomass produced and mass of N leached. The statistical design will be a completely randomized comparing the urea co-crystals to urea, slow release polymer coated urea and no fertilizer. Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two amino groups (–NH2) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. Urea is New Latin, from French WebUrea ices were generated by vapour deposition at temperatures between 10 K and 270 K. It was found that an amorphous phase is formed at temperatures below 200 K. A theoretical modelling of crystalline urea and of a tentative amorphous urea solid phase, as well as of amorphous urea:H 2 O ice mixtures, has been performed.
