STERCOSUL® – Liquid fertilizer based on ammonium thiosulphate
“Unlock the path to higher yield and better quality.”
WHY SULFUR?
Although the most frequently used fertilization elements are Nitrogen (N), Phosphorus (P) and Potassium (K), the interest in sulfur fertilization has significantly increased over the years due to its deficit in nature. This is mainly due to its significantly reduced presence in emissions in industry and the reduced use of organic fertilizers due to the reduction in the volume of livestock production. The effect of sulfur on crop production and quality is significant, depending on the type of crop. Sulfur is present in proteins, participates in the synthesis of some important amino acids (cystine, cysteine, methionine), affects the activity of enzymes and supports the fixation of atmospheric nitrogen by having a positive effect on noodling bacteria. Sulfur is also contained in some secondary metabolites of plants (e.g. glucosinolates). Sulfur is important for plants not only as an element improving the quality of some crops, but also as one of the main factors influencing the nitrogen uptake by plants. It is necessary to fertilize soil with sulfur due to its high mobility in the soil (leaching and erosion).

WHY LIQUID SULFUR?
BENEFITS OF STERCOSUL
- fertilizer with a high sulfur content (12-0-0-26S)
- excellent miscibility with other liquid fertilizers (UAN, urea)
- reduces nitrogen losses in mixes with UAN and urea
- slows down the nitrification process
- in alkaline soils it may expose some microelements
- contains readily available ammoniacal nitrogen
- two forms of sulfur – with rapid and slow release (for plants)
BENEFITS OF SULFUR FOR PLANTS
Nitrogen-sulfur interaction
Sulfur and its activity in plants is linked to nitrogen metabolism. The effective use of nitrogen is directly dependent on a sufficient supply of sulfur. Insufficient uptake of sulfur means reduced synthesis of full-value proteins and thus higher content of free nitrogenous substances of non- -protein nature, including the accumulation of nitrates.
The sulfur requirements of crops
Improving physiological and metabolic processes
Sulfur is a building block of essential amino acids (cysteine, methionine). It is also part of vitamins, coenzyme A and glucosinolates, which are secondary metabolites. Glucosinolates are directly related to the defense mechanism of plants against diseases and pests. They are also
BENEFITS OF SULFUR FOR PLANTS
Improving access to P and microelements in soil (Fe, Mn, Zn)
As sulfur reduces the pH of the soil, especially in alkaline or neutral soils, it can positively affect the access of soil to many microelements, including Zn, Fe, Mn and Cu. Even if soil is rich in iron, the rhizosphere may not allow plants to access this valuable element. Therefore, by adding elemental sulfur to the soil, we can improve the availability of iron (Fe) by changing (lowering) the pH. The addition of sulfur to each batch of nitrogen increases the increases of flour extraction rate and the content and absorption of the micronutrients analyzed, i. je. iron, manganese, zinc and copper. The result obtained shows the so-called additive effect of sulfur.
plant resistance support
Sulfur is known for its fungicidal effects against some pathogens (e.g. powdery mildew). It has a positive effect on the health of some plant species (e.g rapeseed, wheat, sunflower). It inhibits the development of some pathogens, especially in foliar application. However, sulfur can also have a positive effect on the development of induced resistance through cystine formation.
