Urea (carbamide) is the most concentrated solid nitrogen fertilizer, widely used to meet the nitrogen nutritional needs of agricultural crops. The efficiency of using this fertilizer directly depends on understanding its physicochemical properties, choosing the correct application rates, and adhering to technologies that eliminate non-productive nitrogen losses. It is important for agronomists and gardeners to consider the influence of the chemical form of the fertilizer on the soil environment, the specifics of its interaction with other nutrients, and the particularities of crop development in various growing conditions — from open soil to greenhouses.
This collection gathers materials covering key aspects of working with nitrogen fertilizers and plant nutrition systems. The reader will find practical recommendations on the use of urea, evaluating fertilizer quality through composition and impurity analysis, as well as rules for mixing components to prepare optimal nutrient mixtures. The articles also address issues of increasing nitrogen uptake efficiency using nitrification inhibitors, calculating fertilizer application rates depending on the type of substrate, and accounting for the biological needs of vegetable crops to achieve a high harvest and control nitrate accumulation.
