Micronutrient fertilizer LURS® sulphur active
LURS® sulphur active is a high-efficient sulfur micronutrient fertilizer for foliar feeding of field, vegetable and perennial crops.
LURS® sulphur active eliminates effectively sulfur deficiency in plants. It does not contain any ballast additives, so it does not cause leaf burn, is completely absorbed through the leaf surface of plants.
Sulfur regulates growth of the vegetative mass, increases the survivorship rate of plants, increases crop yields. Sulfur is involved in the formation of proteins and vitamins, it is a very important component of mustard oil.
Sulfur has a positive effect on the resistance of plants to diseases such as Alternaria blight and Botrytis. It is a part of amino acids that comprise the protein. Sulfur is involved in the formation of nucleic acids. It enhances the fixation of nitrogen from the atmosphere, as it affects positively nodulation in legumes.
Crops, which are in the greatest need in sulfur, are cruciferous, legumes, sugar beet and potatoes.
When there is sulfur deficiency, there is marbling of young leaves, the leave colour gradates from yellow to red. Upper leaves are first to experience the deficiency of sulfur.
Foliar application of LURS® sulphur active contributes to improvement of nutrition. Sulfur, which is a compound of fertilizer, increases the percentage of protein and starch in wheat, oil content in sunflower, soybean and rapeseed. Sulfur in LURS® sulphur active is in partially reduced form (polysulfides). This allows the plants to include it into the biosynthesis of amino acids and proteins with less energy expenses.
One more element, which is a part of LURS® sulphur active, is sodium. This element provokes growing by stretching and performs a function of osmotic regulation, like potassium.
Sodium is essential for the substance transport through membranes. Therefore, containing sodium, LURS® sulphur active has got a positive effect on the growth of most plants, especially sugar beet. It increases the sugar content, resistance to drought and increases leaf area.
Nitrogen in LURS® sulphur active is in reactive form (amide), which enhances root development.
Compatibility: LURS® sulphur active performs well in tank mixes with herbicides, insecticides, fungicides and biological preparations. Prior to starting preparation of a tank mix, always check the formulations for compatibility.
To avoid leaf and fruit burn, do not apply the formulations in high air temperatures. To obtain the maximum effect, it is advisable to conduct treatments in the evening.
Treatment during the flowering period is not recommended.
LURS® sulphur active has a significant physiological effect on plants, namely:
- increases leaf area by 22%;
- increases disease resistance by 28%;
- enhances root development;
- improves plant nutrition;
- contributes to increase of protein and starch content in wheat, oil content in sunflower, soybeans and rapeseed.
It is recommended for use in conjunction with VIMPEL ®plant growth stimulator.
Attention! The micronutrient fertilizer LURS® sulphur active is not used with formulations that acidify the working solution (pH ≤ 7), due to the formation of hydrogen sulfide.
