Tartaric Acid-Urea Mixture

Tartaric Acid-Urea Mixture

Tartaric acid is a natural, crystalline compound commonly found in tart fruits, unripe grapes, pineapples, and mulberries.

Urea is a favorite ingredient for fertilizers because it contains higher nitrogen content than the alternatives (46 percent). In addition, urea produces few pollutants, and fire hazard is minimal. In granulated form, it is hard, and more resistant to moisture, so most gardeners prefer to use the granules, as opposed to other available forms.
