A fertilizer is any type of organic or inorganic substance that contains nutrients, macroelements, or microelements to maintain or increase the content of these elements in the soil, improve the quality of the substrate at the nutritional level, and stimulate the vegetative growth of the plants. One of the most important macroelements for the plants is nitrogen. Kjeldahl determination is the commonly accepted method of nitrogen determination, based on traditional wet chemistry. An alternative to the classical Kjeldahl method is the Dumas combustion technique, which uses innovative dry chemistry, is easy to use, and is highly accurate.
