Sulfagro Ca fertiliser provides crop plants with the required calcium and sulphur as a slow-acting fertiliser which gradually releases its components.
If the recommended doses of fertiliser are applied in the post-harvest period, the amount of sulphide anions released into the soil will nourish the crop entirely.
A proper nutrition of the crop with sulphur directly influences the metabolism of nitrogen, which is the main crop-forming factor. Plant nitrogen metabolism is closely related to sulphur metabolism. It is assumed that a deficiency of 1 kg S leads to a decrease in nitrogen uptake by a plant from 1 to 3 kg. Nitrogen that is not absorbed by the crop will be dispersed in the environment and will pollute the groundwater and the atmosphere. The rapid growth of leaves under the influence of nitrogen fertilisation causes a higher demand for sulfates for the synthesis of amino acids, production of proteins and fats.
The sulphur in the plant performs structural and metabolic functions, being involved in the synthesis of fats and proteins. If the plants are poorly fed with sulphur then nitrates accumulate in the plant and physiological deficiencies of nitrogen occur.
Sulphur deficiencies lead to a decrease in the quality of the harvested crops , ie a reduction in the fat content of oilseeds or less protein from cereal seeds. Sulphur is involved in lignin synthesis, its deficiency weakens plant tissues and increases the risk of fungal diseases.
This phenomenon becomes dangerous, if at the same time excess nitrogen occurs, it can lead to an increase in plant infection by fungal pathogens. A classic example is the appearance of powdery mildew in wheat crops after the application of high doses of nitrogen.
