Oilseed rape is an annual oil plant of global importance and can be grown in a wide range of soil types. It prefers soils of medium mechanical composition and well-draining, with a pH range of 5.5 to 8. An important characteristic is its resistance to salinity.

The nutrient requirements of oilseed rape, especially in terms of nitrogen, are higher than those of common wheat. However, it returns larger amounts of nutrients to the soil through post-harvest residues than wheat.

The presence of nitrogen is important from the early stages of cultivation to ensure high yields, as it contributes to the formation of a rich leaf surface, pod formation, number, weight and oil content of the grains. Therefore, 1/2 or 2/3 of the amount of nitrogen should be applied during the sowing period with incorporation. In rainfall prone areas, 1/3 of the nitrogen should be applied in early spring. The total nitrogen requirement is 6-10 kg per stremma.

Oilseed rape has a high capacity to absorb phosphorus from the soil due to its root system. Phosphorus has a positive effect on the establishment of a rich root system, the establishment of plants, the early production and the increase in yield.

Potassium is also applied during basal fertilization. From the early stages of cultivation, it enhances plant resistance to low temperature stress, disease and central shoots for resistance to sloping. Sulphur, together with boron, is an essential nutrient during the growing season, with the critical stages of flowering and fruit setting, giving increased oil content of the grains.
