Sulfur is a necessary nutrient for a full nutrition of crops.

It is an important element of plants, is involved in most metabolic processes, and significantly affects germination and production.

Its activity inside the plant is closely linked to Nitrogen.

This is why lack of one of these two elements reduces the utilization of Nitrogen by the plants, suppresses protein synthesis, and halts growth. The main source of Sulfur supply to crops are the quantities returned from the atmosphere through rainfall.

Sulfur (S) was not given much importance in the past, which along with continuously diminishing concentration in the atmosphere has led to its supply being nearly exhausted, which has negatively affected soil fertility and the productivity of crops.

Contemporary agricultural research and practice has highlighted its significant contribution to the full nutrition of crops, and the importance of targeted fertilizing of crops with Sulfur as a requirement for increased yield and the production of quality products.

Nitrogen, Water, Carbon, Oxygen, and Hydrogen are fundamental nutrients for life in general and every living being in nature. In the case of plants, Nitrogen is more involved than any other nutrient in the formation of the plant body and the vital functions of development and production. As a component of chlorophyll, it is involved in the process of photosynthesis and the production of carbohydrates, which form the base of the food chain and the only reason why humans developed agriculture. As a structural element of amino acids, proteins and nucleic acids, Nitrogen has a pivotal role in energy conversions, plant reproduction throughout time, and in the growth and yield of crops.

Lack of Nitrogen leads to reduced fertility of soil, stunted growth, premature decay of plants, reduced production, and deterioration of quality.

Its overabundance favors the production of plants which are vulnerable to diseases and environmental conditions, delays florescence, reduces fruit set, delays maturity, and harms production.

Sufficiency and rational handling of Nitrogen are the most important factors for the health and productivity of crops in contemporary agriculture.

Sources of Nitrogen for plants

Nitrogen is the most abundant atmospheric gas and it occupies 78% of the total volume of the atmosphere. It ranges from 0.05 to 0.4% on the surface layer of the ground and it is found nearly in its entirety in organic form. Despite the fact that crops develop in an environment with an abundance of Nitrogen, plants – with the exception of legumes – cannot absorb and utilize atmospheric Nitrogen. They also lack the capacity to utilize the organic Nitrogen in the soil unless it has already been broken down and converted to absorbable forms. This is why lack of Nitrogen is the most common nutritional deficiency in crops and the main factor that prevents achieving high yields. A rational handling of Nitrogen and sufficient supply of it in crops has been a basic pursuit of agricultural practice throughout time, has been a catalyst in the development of cropping systems, and is directly linked to the development of agriculture from antiquity to this day.


Plants absorb the Nitrogen in the soil in Nitric (ΝΟ3-Ν) form and in Ammoniac (ΝΗ4-Ν) form.

Ammoniac Nitrogen forms a firm connection with the soil and is absorbed by the roots of plants as they grow and come in contact with soil particles. Nitric Nitrogen moves freely in the soil, approaches the roots, and is absorbed by plants through the water in the soil. It is fundamentally important that both forms of Nitrogen are present in the soil for crops to have a healthy development, for increased yield, and for a better production quality.
