Sulphur content fertilizers
Nitrogen sulphates NS 30:7 / 29:8 / 26:13
High-nitrogen fertilizers with sulfur. A combination of ammonium and nitrate nitrogen provides for plant supply with this nutritive element throughout their vegetation period. The products contain sulfur in the form of soluble sulfates. Application of these fertilizer types allows to increase the amount of phosphorus taken by the plants from the soil. These products are effective in production of cereal crops, oil crops, crucifers and fodders.
Nitrogen sulphate NS 30:7 is a new physiologically neutral fertilizer. The improved pellet strength makes this product a perfect component of sulfur-containing fertilizer mixtures (an excellent alternative of ammonium sulfate). The product improves plant phosphor adsorption and, additionally, contributes to extraction of phosphates that have accumulated in the soil. It improves product quality (increases protein content in cereal crops and oil content in oil crops). The product demonstrates excellent physical and chemical properties (does not cake or produce dust).
Nitrogen sulphate NS 26:13 is one of the most popular sulfur-containing nitrogen fertilizers in Europe. This physiologically acidic fertilizer is used in alkaline (or neutral) soils; it increases soil acidity and improves the characteristics connected with the uptake of phosphorus that was added to soil over the previous years.
Non-acidic forming nitrogen-calcium fertilizer. Calcium increases the quality of tubers, roots, fruits and vegetables, it strengthens the hull and improves the color of fruits and vegetables. CAN+S has neutral soil reaction and creates optimal conditions for nitrogen uptake by plants. It can be used for all types of soils, but the most effective usage is seen on acidic soils. CAN+S is widely used for cabbages and rape (biodiesel).
NPKS 16:16:16:8 / 15:15:15:10
One of the widely used and effective complex fertilizers with balanced proportion of nutrient elements in water-soluble form. It is used as basic spring fertilizer and as presowing fertilizer in autumn for under-winter plowing. It is highly recommended for all kinds of soils and for all types of agricultural crops - cereal, corn, sugar beet, grasses. It's also ideal for rape and oilseeds because of high content of sulphur.
NPS 14:34:0:8 / 20:20:0:14 / 16:21:0:14
A widely used granular fertilizer has perfect phosphorous-solubility characteristics. The nutrient balance is very effective on soils with low phosphorous content. Ammonium nitrogen helps better phosphorous uptake. NPS is used on all types of soils for all crops. This product can be used as main spring fertilizer as well as for additional fertilization during vegetation period. Perfect for greenhouses, wheat, sunflowers and other oil crops.
Ammonium nitrate-sulphate NS 26:14
One of the most popular nitrogen-sulphur fertilizer in Europe. Nutrient composition is designed for further improvement of nitrogen uptake by plants. It's an acidic fertilizer - being applied to alkaline (or neutral) soil it acidifies soil and increases availability of phosphorus applied to soil in previous years. It can be used on all types of soils and for all crops. It is an ideal fertilizer for rapeseed and other crucials.
NPKS 27:6:6:2 / 22:7:12:2
Highly effective complex mineral fertilizer containing all primary elements necessary for growth and development of plants. These products can be used for main application before planting as well as a spring top dressing. They are appropriate for all crops according to crop requirements and soil tests. Due to sulfur content this product shows good results for legumes, cereal and oilseed crops.
This fertilizer is good for reclaimed soils with medium concentration of movable forms of P and K. It suits for many crops as general purpose product. Also the ratios N:P and N:K as 2:1 make this product a good presowing fertilizer for grain and tilled crops as well as for grasslands - hay production or extensive grazing. Sulphur applied together with nitrogen takes part in protein synthesis processes.
DAP+S / MAP+S 18:47:0:3 / 12:52:0:2
Granular concentrated NP fertilizer with the nutrient balance ideal for improving plant resistance to aggressive environment such as drought, frosts and as well as diseases of different genesis. High phosphorous content helps sugar accumulation in fruits and routes. DAP is widely used on all crops and soils as main fertilizer and also for spring and summer additional fertilizing for acceleration of fruits ripening.
Potassium Magnesium Sulphate (K2SO4 * MgSO4)
Potassium magnesium sulphate is a double salt and contains 18% K (22% K2O), 11% Mg and 22% S. It has the advantage of supplying both Mg and S and is frequently included in 8 mixed fertilizers for the purpose on soils deficient in these two elements. They are particularly useful when low levels of chloride are desired, as is often the case for crops such as tobacco, potatoes, peach, some legumes and turf grass.
Ammonium sulfate (NH4)2SO4
This fertilizer has a high water solubility, although the proportion N:S~1:1 is too high for most plants. It should not be used for acidic soils due to its low pH level. The most part of commercially available ammonium sulfate is a crystalline product, which makes it hard to mix it with other pellet fertilization products.
A variety of S-bentonite fertilizers have been produced to improve the effectiveness of granular elemental S products by incorporating 5 to 10% by weight of a swelling clay such as bentonite. Particles of S-bentonite are sized for blending with solid N, P and K fertilizers. When it is applied to soil, this bentonite component imbibes soil moisture, causing fertilizer granules to disintegrate into finely divided S, which is more rapidly converted to SO42-. This material has gained wide acceptance as a source of plant nutrient S for high analysis, bulk blend formulations because it provide elemental S in an acceptable physical form that can be converted easily in to SO42- form in soil.
Sulphur coated urea (SCU) fertilizer is formulated for increased efficiency in the use of urea consisting of an S shell around each urea particle. It contains 77 to 82% of urea (36 to 38% N) and 14 to 20% S coating. Although S in the coating may not be sufficiently available to correct deficiencies during the early season of the first year after application, it will become an important source of plant available S in the latter growing season and succeeding year.
Ammonium thiosulphate solution (ATS)
ATS is a popular source of S for use in liquid fertilizers because of its solubility and compatibility with various ions. Fertilizer-grade ATS is in a 60% aqueous solution with a 12-0-0-26S analysis. It is compatible in any proportion with neutral to slightly acidic phosphate-containing solutions or suspensions, as well as with aqueous NH3 and N solutions, to make a wide variety of N-S, N-P-S, and N-P-K-S formulations. ATS can be applied directly by drip, sprinkler or flood irrigation.
Urea-ammonium sulphate (UAS) solution
This liquid fertiliser consists of urea and ammonium sulphate and especially appropriate for use with drip irrigation systems.
Calcium sulfate CaSO4 (calcium sulfate, phosphogypsum)
A cheap source of sulfur, although having disadvantages such as its low solubility in water and, as a result, its poor availability for plants.
A cheap source, although one should bear in mind that pure sulfur cannot be taken up by plants. It is adsorbed only in the form of sulfate ions. In-soil oxidation of sulfur to sulfate ions takes place only under certain conditions (temperature, humidity, etc.) This takes up to several weeks. Also it should be taken into consideration that the conversion of elemental sulfur into sulfate ions in soil does not exceed 10-15%.
