In addition to that, it is a known fact that the nitrogen form in the soils affects the root development of the plants. RÖMHELD (1986) demonstrates that ammonium-based plant nutrition results in significantly intensified secondary root growth as well as a decrease in the pH level of the rhizosphere. Following these processes, the plant can take up water and nutrients better than before. Additionally, further nutrients such as phosphorus and micronutrients (e. g. Mn) are being mobilised and become available to the plants.
Through the delayed implementation of ammonium nitrogen, fertiliser nitrogen remains in a stabilised form in topsoil and is safeguarded against unwanted nitrate storage at deeper soil levels. In the context of an ammonium-based plant nutrition, nitrogen applications can be combined, saving you several work steps. Since the stabilised nitrogen can be used earlier and in higher quantities, it is especially useful in areas with early summer dryness due to use of winter moisture by roots. Regardless of weather conditions, it is in the right place and at the right time. This makes nitrogen stabilised fertiliser ideal for both humid/wet and for dry areas and significantly reduces weather-related growth risks. Supplying the plants with nutrients on time and in accordance with their needs improves the size and quality of the yield and results in improved nitrogen efficiency.
