Organic Fertilizer (Compost)

about this product

The science of plant nutrition dates back to the beginning of the history of agriculture when humans realized that soil becomes poor following several rounds of cultivation and the subsequent products do not grow as much as the early products. The soil is reinforced if substances such as manure and chemical fertilizers are added to it, but today environmental problems are among the problems attributed to overuse of chemical fertilizers. With years of research, experts of Parsian Mineral Processing Company have managed to discover compounds containing all of the minerals required by a plant. This company’s product contains more than 60 elements including macro and micro elements as well as rare mineral and organic elements that meet all of the nutritional needs of plants and immensely contribute to soil amendment and growth of plants.

Product Applications

Supplying all of the nutrients required by plants

Increasing organic materials of soil

Highly resisting leaching

Supplying food to soil organisms

Description of the Product Applications

Mineral fertilizers are grouped into two categories:


1. Fertilizers containing elements such as nitrate, nitrogen, phosphate, and potassium hydroxide are known as macro-element fertilizers.


2. Fertilizers containing rare elements such as iron, zinc, boron, magnesium, manganese, and sulfur are known as micro-element fertilizers.


Different Types of Mineral and Chemical Fertilizers


Ammonium nitrate:


It contains 1.4 of nitrate with immediate and continuous acid effects, and approximately 25 g of this fertilizer is used per square meter.



Ammonium sulfate:


It has a gradual, continuous and strong acid effect, and 15 to 30 g of this fertilizer is used per square meter.




Ammonium and calcium nitrate mix:


It contains 4.1 of nitrate and immediately affects plants. Moreover, 40 g is used per square meter.




Calcium nitrate:


It immediately affects the calcium-containing earth and approximately 40 g is used per square meter.






It has an immediate impact. 90% of it is solved in water and app. 50 g is used per square meter. It is suitable for lands that are short of phosphorus.




Potassium hydroxide:


It suits lands that are short of potassium hydroxide and magnesium, and approximately 30 to 70 g of it is used per square meter.





It contains large amounts of nitrogen and has an immediate impact. It is mostly used when the soil is short of nitrogen, and since soil loses nitrogen quickly the performance is improved if urea is covered with sulfur. (Sulfur-coated urea fertilizer)


Magnesium sulfate:


It immediately affects plants and app. 20 g is used per square meter.


Calcium carbonate:


It contains 80% of calcium carbonate and suits lands short of calcium. Approximately 30 g of this fertilizer is used per square meter.




It is designed to amend heavy soils. Calcium oxide and calcium hydroxide are used for lands that are short of calcium. The choice depends on the soil of the region.






It is of different types, each of which is used for a specific purpose. For instance, green kristalon is used for growth of leaves and red kristalon is used for the production of fruit.






It is available in the powder and liquid forms, and it used to overcome the shortage of iron in plants. It is useful for young leaves in the chlorosis condition (in which the leaves are yellow but the veins are green). In the severe iron shortage condition, the leaves become white. Three to five grams of the liquid form is used per square meter.






Shortage of zinc in trees creates corky and cracked tree barks, leads to decay of gardens, and change of color of plants. Sometimes the result of zinc shortage is the production of malformed fruits. Boron fertilizer is used to overcome the shortage of boron in plants. (Approximately 2 to 5 g is used per square meter.)






Those parts of older leaves that are between the veins become yellow and then turn red. Necrotic spots in the margins of leaves curl up. Approximately 3 g is used per square meter.






Yellow spots appear on the leaves and fruits of trees. The leaves and fruits turn brown and wither. Approximately 3 g is used per square meter.






Young leaves become yellow while the veins are lighter than the tissue between them and the leaves are narrower. Five grams of its powder form is used per square meter, or approximately 20 g of sulfur-coated urea powder is used per square meter.






The spaces between veins, which are in the chlorosis condition, become yellow and the edges turn purple. Approximately 3 g is used per square meter.
