In addition to its role as a fertilizer, Ferrous Sulfate offers various other applications across different industries:

Water Treatment: Ferrous Sulfate is utilized in water treatment processes to remove impurities such as hydrogen sulfide and excess phosphates. It aids in clarifying water and reducing odors, making it an essential component in municipal water treatment facilities and industrial wastewater treatment plants.

Colorant: Ferrous Sulfate is employed as a mordant in textile dyeing and printing processes, where it helps fix dyes onto fabrics and enhances colorfastness. It is also utilized in the production of inks, pigments, and paints, contributing to their color intensity and durability.

Algae Control: In aquaculture and pond management, Ferrous Sulfate is utilized to control the growth of algae and unwanted aquatic vegetation. By disrupting the photosynthetic process of algae, it helps maintain water quality and prevents excessive algae blooms, thereby supporting a balanced aquatic ecosystem.

Animal Feed Additive: Ferrous Sulfate is included in animal feed formulations to supplement livestock diets with essential iron. It aids in promoting healthy growth, preventing anemia, and ensuring optimal nutrient absorption in animals such as poultry, swine, and cattle.

Soil Acidification: In agricultural practices, Ferrous Sulfate is sometimes used to acidify soil with high pH levels, enhancing the availability of certain nutrients to plants. It can be applied selectively to crops that thrive in acidic conditions, helping to optimize soil pH for improved growth and yield.

These diverse applications highlight the versatility and significance of Ferrous Sulfate across various industries, making it an indispensable compound with widespread utility beyond its role as a fertilizer.

Key Features:

High Iron Content: Our fertilizer contains 20% iron derived from hexahydrate ferrous sulfate, providing plants with a concentrated source of iron to address chlorosis and iron deficiency effectively.

Chlorosis Treatment: Chlorosis is a common condition in plants characterized by yellowing of leaves due to insufficient chlorophyll production. Ferrous Sulfate serves as an effective remedy for chlorosis, as it provides plants with readily available iron, which is essential for chlorophyll synthesis. By correcting iron deficiency, Ferrous Sulfate helps restore the vibrant green coloration of leaves, promoting healthier foliage and improved photosynthetic activity.

Iron Deficiency Correction: Iron deficiency is a widespread issue in many plants, leading to stunted growth, reduced vigor, and poor crop yield. Ferrous Sulfate offers a direct and efficient solution to this problem by supplying plants with a concentrated source of iron. As plants absorb the iron from the fertilizer, they can overcome deficiency symptoms and thrive, leading to enhanced growth, flowering, and fruiting.

100% Water Soluble: Formulated for maximum solubility, our fertilizer dissolves quickly and completely in water, ensuring rapid absorption by plant roots and efficient nutrient uptake.

Anti-Caking Agent: Enhanced with calcium carbonate as an anti-caking agent, our fertilizer remains free-flowing and resistant to clumping, ensuring effortless storage, handling, and application.

Versatile Application: Suitable for use in gardens, farms, nurseries, and greenhouse operations, our fertilizer is ideal for a wide range of plants, including ornamentals, vegetables, fruits, and crops.

Fast-Acting Formula: With its potent blend of nutrients, our fertilizer delivers fast-acting results, visibly improving plant health, vigor, and coloration within a short period.

Promotes Lush Growth: Enriched with essential iron, our fertilizer promotes lush foliage, robust growth, and vigorous flowering, enhancing the overall aesthetics and productivity of plants.

Multiple Uses: In addition to its role as a fertilizer, our product can be utilized for water treatment, nutritional supplementation, colorant production, algae control, animal feed, and soil acidification, providing versatility and value across various applications.

Professional-Grade Quality: Manufactured to the highest standards of quality and purity, our Ferrous Sulfate Fertilizer is trusted by professional growers, landscapers, and agricultural experts for consistent performance and exceptional results.

Application Rate:

Flowers & Vegetables: Apply at the rate of 1/4 to 1/2 pound. (1/2 to 1 cup) per 100 square feet.

Trees & Shrubs: Apply at the rate of 1/2 to 1 pound. (1 to 2 cups) per 100 square feet.

Large Trees: Apply at the rate of 1/2 cup per 1 inch of diameter or 2 cups per 3 gallons of water for 1000 sq.ft.

Foliar Application:

  • Mix at the rate of 1-2 Tablespoons per gallon of water or 5-8 Pounds per 100 Gallons of water.
  • For small plants with relatively sparse foliage, such as young seedlings or annual flowers, one gallon of foliar spray may cover approximately 50 to 100 plants.
  • For larger plants with denser foliage, such as shrubs or mature trees, one gallon of foliar spray may cover fewer plants, typically around 10 to 20 plants.
  • Spray the diluted solution directly onto the foliage of plants using a handheld sprayer or pump sprayer.
  • Ensure thorough coverage of both sides of the leaves, but avoid excessive dripping or runoff.
  • Apply the foliar spray early in the morning or late in the afternoon to minimize the risk of leaf burn from sun exposure.
  • Repeat the foliar application every 2 to 4 weeks during the growing season, or as needed based on the severity of iron deficiency symptoms.
