UREA 46%N
Urea is a high-concentration nitrogen fertilizer with its nitrogen in the form of urea. It is the most widely used fertilizer in the world, even though industrial production started only in the 1950s. It is used in pre-sowing fertilization because it allows the gradual conversion of urea nitrogen into ammonium and nitrate forms, depending on the climatic and agrochemical conditions in the soil. In autumn basic fertilization, urea is used for the rapid decomposition of plant residues and the activation of organic nitrogen in the soil.
Composition
| Nitrogen | 46% |
| Biuret | Up to 1% |
| Moist | Do 0,5% |
KAN 27%N
KAN is a well-known nitrogen fertilizer for all agricultural crops. It contains half of the nitrogen in the ammonium and half in the nitrate form, so it works quickly and has some extended action, meeting the plant's nitrogen needs over a specific period. With its dolomite content (around 23%), it contributes to the partial neutralization of soil acidity, and its magnesium content partially satisfies the plant's needs for this nutrient.
Composition
| Nitrogen | 27% |
| MgO | 4,5 - 5,5% |
| Cao | 6,5 - 8,5% |
| Moist | Up to 0,5% |
NPK 15-15-15
NPK 15-15-15 is a complex mineral fertilizer with an equal ratio of nitrogen, phosphorus, and potassium. This formulation provides plants with readily available nutrients, and potassium is present in the form of soluble chloride. The granules of this fertilizer are light gray in color, sized between 2 – 5 mm, and treated to prevent them from clumping. It is used for both basic and pre-sowing fertilization on various types of soil and can be applied manually, with agricultural machinery, or by aircraft. NPK 15-15-15 is an ideal choice for crops with high demands for nitrogen, phosphorus, and potassium and is odorless.
Composition
| Nitrogen | 15% |
| Phosphorus | 15% |
| Potassium | 15% |
