Liguid fertilizers based on polysulphides

 The liquid fertilizer line combines tradition and new answers to challenges. These are solution concentrates of sulphur, mainly in polysulfide form containing primary and secondary nutrients (nitrogen, potassium and calcium), also in combination with trace elements (boron) and potassium humate.

They provide effective nutrition at the time of the highest crop consumption, positively affect the health status and quality of crops grown. Specifications of chemical composition create space for secondary effects in the direction of plant protection.

  • SULKA-K

SULKA-K is a multipurpose liquid fertilizer designed to supplement selected nutritional ingredients and to improve, respectively maintain good health of plants. It allows various applications - foliar to leaf, spraying on the soil, spraying in winter and pre-season to "wood" until flowering. The fertilizer is also suitable for mordanting the planting stock of garlic, onion and tuberous plants. Foliar application is designed especially for crops and plants consuming a lot of potassium (cucumbers, pumpkins, tomatoes, flowers, fruit trees, vines) and for crops with high sulphur need (bulbous plants, oilseed plants, cabbages). It is a solution-concentrate of sulphur, mostly in polysulfide form , containing nutrients: nitrogen, potassium and calcium.

  • SULKA-Ca

SULKA-Ca is a liquid fertilizer in the form of a solution of sulphur concentrate, predominantly in polysulphide form, with a high calcium content. It allows various applications - foliar to leaf, spraying on the soil, spraying in winter and pre-season to "wood" until flowering. The fertilizer is also suitable for mordanting the planting stock of garlic, onion and tuberous plants. Foliar application is suitable for prevention and elimination of symptoms of calcium deficiency in plants. It is mainly intended for crops with high sulphur need (bulbous plants, oilseed plants, cabbages).

  • SULFERT-N

SULFERT-N is a multicomponent liquid fertilizer in the form of a highly concentrated aqueous urea solution with polysulphides and potassium and calcium thiosulphates. Compared to the previous types, the fertilizer is characterized by a high content of water-soluble calcium and polysulfide sulphur. The fertilizer is applied after dilution with water, depending on the date of application, as dressing or foliar spray. It is designed for large-scale use for sulphur-intensive crops such as cereals and colza. It is applied at the recommended dose of 3 to 5 l / ha in one or more applications for acute deficiency of sulphur and nitrogen.

  • SULFERT-NKS

SULFERT-NKS is a multicomponent liquid fertilizer in the form of highly concentrated aqueous urea solution with polysulphides and potassium and calcium thiosulphates. The ratio of nitrogen and sulphur in nutrient content is 2: 1. The solution form of nutrients and their unlimited water solubility allow simple and effective application with a high degree of nutrient utilization. The fertilizer is applied after dilution with water, depending on the date of application, as dressing or foliar spray. It is intended for large-scale use for sulphur-intensive crops such as cereals, rape, bulbous plants, sprouts, potatoes. It is applied at the recommended dose of 3 to 5 l / ha in one or more applications for acute deficiency of sulphur, potassium and nitrogen.

  • SULFERT-NKS Plus

SULFERT-NKS Plus is a multi-component clear liquid fertilizer of reddish-brown colour with 35% nutrient content. It is a concentrated aqueous solution containing urea nitrogen, potassium in non-chloride form, sulphur in polysulfide and thiosulphate form and water-soluble calcium.

  • SULFERT-Bór

SULFERT-Bór is a liquid combined fertilizer containing nitrogen, potassium, sulphur in form of polysulfide and thiosulphate and boron micronutrient. This fertilizer, which can be used throughout the whole vegetation, provides a harmonized nutrient content and a high content of water soluble boron. It is designed to eliminate the boron deficit and to cover increased demand for boron consumption in case of some crops, particularly oilseed plants (rape, poppy seeds), fruit trees, vines and cereals. Boron positively influences the proper flowering of plants and fruit stems. Combined with the high polysulfide sulphur content, it also contributes to the good health of plants and increases their resistance to disease. The fertilizer is applied as spray on leaves and also as a dressing.

  • SULFERT-Humát

SULFERT-Humát is a liquid combined fertilizer with beneficial effects on both plants and soil. In addition to the nutrients as nitrogen, potassium and sulfur (in a polysulfide and thiosulfate form) it also contains biologically active humic substances (potassium humate and humic acids), which act as growth promoters, makes the growth of the root system of plants, their germination and development, helping plants to receive nutrients from the soil and also from the fertilizer itself. Combined with a high polysulfide sulphur content, it also contributes to the good health of plants and increases their resistance to disease. The fertilizer is applied as foliar spray and even as dressing. The recommended use is mainly for fruit trees, vegetables, potatoes and grape vines.
