Nitrogen Fertilization

Holistic solutions in a complete range of nitrogen fertilizers

Cotton and corn are two of the most economically important crops, but also among the most widely cultivated across the length and breadth of our country. The needs for surface fertilization in both crops are mainly in nitrogen as the entire amount of phosphorus and potassium has been applied during the basic fertilization.

Nitrogen is responsible for photosynthesis and is the structural component of amino acids, proteins, coenzymes and chlorophyll. This means that adequate and balanced plant nutrition at critical stages of cultivation is the key to achieving maximum production potential.

Corn in the first stages of growth takes in small amounts of nutrients, while in the following vegetative stages and until reproductive growth, the rate of uptake of nutrients increases rapidly, while during the filling of the grain it gradually decreases. The maximum daily nitrogen uptake was observed between 70-90 days after sowing. Therefore, in order to achieve adequate feeding of the plants, surface fertilization starts from the 6-7 leaf stage. The method of fertilization is usually determined by the irrigation method, so we have a dose that contains the entire amount of surface nitrogen or in 2-3 doses.

In cotton, nitrogen requirements are variable and are influenced by many factors. The application of the optimal amount of nitrogen creates a balance between the vegetation and the fruiting organs, an increase in the chlorophyll content of the leaves and the intensity of the photosynthetic activity of the plants. Excessive use of nitrogen causes vigorous growth of the plant at the expense of fruiting. The time of nitrogen application depends on the soil and climate conditions of each region.

Agrohellas, having a full range of nitrogenous fertilizers, proposes the types 46-0-0, 40-0-0, 21-0-0 and 35-0-0, in addition it has two categories of hindered fertilizers, Premium 46-0-0, Premium 40 -0-0 with NBPT.
