Farmers and gardeners apply phosphate-based fertilizer to plants and soil to boost local phosphorus (P) levels. Young plants are especially vulnerable to deficient P levels, but almost every plant needs it to maintain healthy growth. Artificial phosphate fertilizer and manure or compost are used together to revitalize severely depleted soil. Phosphate fertilizers fall into one of four basic categories: rock phosphates, superphosphates, ammonium phosphates or polyphosphates. Each type of fertilizer is composed of different substances and chemical ratios.
Phosphate fine 21% (Russia)
Phosphate fine powder 24,5%( Russia)
Rock Phosphate (Apatite)
Deposits of rock phosphate form naturally in geological formations. It is harvested, ground to powder and added to soil as a source of phosphorus. A Michigan State University bulletin, titled “N-P-K Fertilizers,” reports a steady decline in the availability of rock phosphate on the market. The author cites the material’s high transportation costs and poor water solubility as catalysts for its diminished use in agricultural practices. Rock phosphate still has limited use in domestic cultivation and is refined as an ingredient in other advanced fertilizers.
Rock Phosphates 36% P2O5 Togo & 38% P2O5 (Nauru origin)
Rock Phosphates 24%, 26%, 28%, 29% and 30% P2O5 ( Egyptian origin)
Rock Phosphate 32% (Jordan origin)

Single Super Phosphate
Normal super phosphate is a stronger and more soluble compound than rock phosphate, but it is significantly less potent than concentrated super phosphate or ammonium compounds. The newer concentrated compound contains 46% phosphate, while the normal variety has 20%. Neither of the two supplies nitrogen, a desirable nutrient found in other fertilizers.

Granular Triple Super Phosphate
Triple super phosphate is made by the action of phosphoric acid on raw rock phosphate (also called appatite). It typically contains 46% phosphate, soluble in neutral ammonium citrate and water. Of this, typically 90% is soluble in water alone. Because the phosphate on TSP is never completely water-soluble, it cannot be used in the manufacture of clear-liquid fertilizers.
MAP (Monoammonium Phosphate)
N:P:K = 12-61-0
- As a high grade fertilizer for the production of complex fertilizers as well,
could be used itself as solution: additional fertilizers, in hotbed for
vegetables and flowers;
- As feed admixtures for the stock-breeding;
- As additional fertilizers for yeast production (feed, alcohol, bakery, beer),
- For textile impregnation, plywood and timber for fire barrier;
- For preparing fire barrier solutions used in wooden construction treatment;
- For the production of fire-extinguisher powder.
DAP (Diammonium Phosphate) N:P:K = 21-53-0;18-46-0
Diammonium phosphate fertilizer is a plant food that is rich in the mineral phosphorus. It is widely used among farmers in the production of grain and row crops, such as corn, wheat, rye and some lawn grasses. Some farmers may choose to blend this type of plant food with other fertilizer forms to meet the specific needs of their crops and soils. It may be applied using a variety of methods before, during, or after crops have been planted.
● Standard MOP can be white or pink:
○ White MOP is applied directly to the soil, for producing compound NPK fertilizers, and for other industrial needs. We supply this mainly to China, Russia and Europe. White MOP is produced in the following varieties: 95% and 98%.
○ Pink MOP is applied directly to the soil and we supply this primarily to India and Southeast Asia.
● Granular MOP is a premium product bought mainly in countries using advanced soil fertilization methods. Granulation slows down the absorption of fertilizer nutrients into soil, thus prolonging their action. We export our granular MOP principally to Brazil, the USA and China, where it is applied directly to the soil or blended with nitrogen and phosphate fertilizers. Granular MOP costs slightly more than other types of potash fertilizers.
Ammonium sulfate, (NH4)2SO4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen as ammonium cations, and 24% sulfur as sulfate anions. In fertilizer the purpose of the sulfate is to reduce the soil pH.
Copper (II) sulfate is the chemical compound with the formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or grey-white powder, whereas the pentahydrate (CuSO4•5H2O), the most commonly encountered salt, is bright blue. The anhydrous form occurs as a rare mineral known as chalcocyanite. The hydrated copper sulfate occurs in nature as chalcanthite (pentahydrate), and two more rare ones: bonattite (trihydrate) and boothite (heptahydrate). Archaic names for copper (II) sulfate are “blue vitriol” and “bluestone.”
A colorless or white crystalline compound, K2SO4 is used in glassmaking and fertilizers and as a reagent in analytical chemistry.
