Petro Tejarat Irsa Company is the exclusive representative of TERSAN PUGLIA, which has 50 years of experience in producing organic fertilizers for both traditional and modern agricultural industries. After sampling the soil in Iran and identifying its nutritional elements and deficiencies, the company began producing organic fertilizers tailored to the needs of Iranian farmers. Since microorganisms are one of the most important features of bio-fertilizers, in order to preserve them, the products of this company are made into pellets without any physical or mechanical pressure. Additionally, they are dried at low temperatures using a conveyor belt drying system, ensuring long-term preservation. The result of this temperature regulation process is a product in which microorganisms remain alive and an organic medium is provided for their growth. Since the pellet size greatly influences the desired outcome, the pellets are separated into sizes ranging from 2 to 5 millimeters using a sieving system. The advantages of this size for farmers include increased surface area, better access to microorganisms, and easy spreading across the surface. Soil can only reach its maximum fertility when all its components are in a state of natural balance. If this balance is disrupted, the nutrients provided by fertilizers will have no effect because a microbiologically suitable environment will not exist, preventing the absorption of nutrients by plants. One of the properties of the bio-fertilizers from this company is the transfer of soil nutrients in a form that is accessible for plant absorption. Benefits of this product for improving soil structure and plant growth include: Reduced erosion due to stronger soil aggregates and decreased groundwater flow Improved root penetration for access to soil moisture, nutrients, and oxygen Suppressive effect on soil pathogens, reducing the need for chemical pesticides Provides a medium for the absorption of nutrients in the soil that are not easily absorbed This product helps organic materials remain in the soil, thus reducing the greenhouse effect. Another feature of this product is that, by improving physical structure, it is suitable for any type of soil, regardless of particle size. The packaging of this product is highly modern, resistant to ultraviolet rays, and 100% waterproof, allowing for the storage of the product outdoors without any change in its properties.
