Fertilizer Ingredients for Agriculture & Soil Health

Cerco Group supplies primary plant nutrients—nitrogen (N), phosphorus (P), and potassium (K)—used in base fertilizers for row crops, pasture, and specialty agriculture.

Macronutrients are the primary nutrients that plants require in large quantities for optimal growth and development.

Nitrogen (N) – Promotes vigorous leaf and stem growth.

Common Ingredients:

• Ammonium Nitrate

• Urea

• Ammonium Sulfate

• Calcium Nitrate

• Anhydrous Ammonia

Phosphorus (P) – Supports energy transfer, root development, and flowering.

Common Ingredients:

• Superphosphate

• Triple Superphosphate

• Monoammonium Phosphate (MAP)

• Diammonium Phosphate (DAP)

• Rock Phosphate

Potassium (K) – Essential for water regulation, disease resistance, and overall plant health.

Common Ingredients:

• Potassium Chloride (Muriate of Potash)

• Potassium Sulfate

• Potassium Nitrate

We source essential trace elements such as zinc, manganese, boron, copper, and iron, used to correct deficiencies and improve crop performance.

While needed in smaller quantities, micronutrients are just as essential for plant metabolism and health.

Iron (Fe) – Crucial for chlorophyll production.

Common Ingredients: Iron Sulfate, Iron Chelates

Zinc (Zn) – Important for enzyme function and protein synthesis.

Common Ingredients: Zinc Sulfate, Zinc Oxide, Zinc Chelates

Copper (Cu) – Supports photosynthesis and respiration.

Common Ingredients: Copper Sulfate, Copper Oxide

Manganese (Mn) – Aids in photosynthesis and enzyme activation.

Common Ingredients: Manganese Sulfate, Manganese Chelates

Boron (B) – Essential for cell wall formation and reproductive growth.

Common Ingredients: Borax, Boric Acid

Molybdenum (Mo) – Aids nitrogen fixation and metabolism.

Common Ingredients: Ammonium Molybdate

Chlorine (Cl) – Supports osmotic regulation and photosynthesis.

Common Ingredients: Potassium Chloride, Calcium Chloride

Cerco Group offers inputs compliant with organic production standards, including composted materials, manure-based fertilizers, and natural mineral sources.

Organic amendments improve soil structure, microbial activity, and long-term fertility.

• Compost – Decomposed organic matter that enhances soil quality.

• Manure – Provides organic nutrients and improves soil fertility.

• Peat Moss – Enhances water retention and aeration.

• Biochar – Helps with water retention and nutrient availability.

• Worm Castings – Rich in nutrients and beneficial microbes.

• Seaweed/Kelp – Provides trace minerals and growth hormones.

• Fish Meal – Natural source of nitrogen, phosphorus, and micronutrients.

We provide lime, gypsum, and other products that help growers regulate soil pH, improving nutrient availability and long-term soil structure.

Maintaining proper soil pH is essential for nutrient availability and crop health.

• Lime (Calcium Carbonate) – Raises soil pH (reduces acidity).

• Dolomitic Lime – Raises pH while adding magnesium.

• Sulfur – Lowers soil pH (increases acidity).

• Iron Sulfate – Lowers pH and provides iron.

Our team sources products like humates, gypsum, and carbon-rich inputs that support soil health, water retention, and microbial activity.

These products enhance soil structure, aeration, and root development.

• Gypsum – Improves soil structure and provides calcium and sulfur.

• Humic Acids – Enhance nutrient availability and microbial activity.

• Silica – Strengthens cell walls and improves plant resilience.

• Feather Meal - Slow release nitrogen source that promotes soil fertility and sustained plant growth.

Cerco Group supplies EDTA- and EDDHA-chelated nutrients for foliar and soil application—improving micronutrient uptake and plant availability in various pH conditions.

Chelated nutrients improve nutrient uptake, especially in alkaline soils.

• Chelated Iron – Enhances iron availability in high-pH soils.

• Chelated Copper, Zinc, Manganese – Increases absorption and efficiency of micronutrients.

We help growers and blenders source coated, encapsulated, and stabilized fertilizers designed to provide sustained nutrient delivery and reduce leaching.

Slow-release formulas provide long-term nutrient supply with minimal leaching.

• Coated Urea – Nitrogen release controlled by a polymer or sulfur coating.

• Polymer-Coated Fertilizers – Extended nutrient release over time.

• Organic Slow-Release Fertilizers – Derived from composted manure, fish meal, or organic matter.

Cerco Group sources biological additives, mycorrhizal fungi, rhizobacteria, and plant-growth-promoting compounds to support yield, root health, and resilience.

These natural products support root growth, nutrient absorption, and plant resistance.

• Mycorrhizal Fungi – Enhances root expansion and nutrient uptake.

• Rhizobium Bacteria – Assists in nitrogen fixation for leguminous plants.

• Trichoderma – Beneficial fungi that suppress soil pathogens.

• Seaweed Extracts – Contains plant hormones that promote growth.

• Amino Acids – Improve nutrient absorption and plant metabolism.

For growers who need protection tools, we can assist in sourcing select insecticides, fungicides, and natural pest control agents for integrated fertility and pest management.

Some fertilizers include natural pest and disease control solutions.

• Neem Oil – A natural pesticide and fungicide.

• Sulfur – Used as a fungicide and also aids in lowering soil pH.
