Ammonium compounds play a key role in modern plant cultivation, providing crops with accessible nitrogen nutrition. Understanding the transformation processes of nitrogen compounds in the soil, the mechanisms of soil absorption capacity, and the physiological characteristics of the assimilation of various chemical forms of fertilizer is essential for building effective nutrition systems. The agronomic value of ammonium forms lies in their ability to rapidly influence plant growth and development, while their competent application requires consideration of the specific characteristics of individual crops, soil types, and application technologies.
This collection contains materials that reveal the characteristics and application regulations of key nitrogen fertilizers: ammonium sulfate, ammonium nitrate, ammophos, and calcium cyanamide. Readers will find recommendations here on calculating application rates, methods for laboratory analysis of substrates, rules for component compatibility when mixing fertilizers, and methods for managing mineral nutrition in various agroclimatic conditions. The articles also cover issues regarding the production of complex fertilizers, such as nitrophoska, and provide data on the influence of microflora on nitrogen availability, which will help specialists and gardeners optimize the application of top dressing to achieve target yield indicators.
