1. What is the composition of the Nano Iron?

Nano iron contains ferrous sulfate (15%) as the primary iron source, combined with citric acid (15%) and formic acid (2.5%) as chelators and stabilizers. Lysine (3%) serves as a natural amino-acid chelate enhancing bioavailability, while gelatin (0.25%) and PEG 6000 (0.25%) provide a protein matrix and surfactant stabilization. Xanthan gum (0.03%) controls viscosity, and parabens (0.15%) preserve formulation integrity. The active ingredients are encapsulated in a chitosan-based biopolymer that creates nano-scale particles (1-100 nm), dramatically improving plant uptake efficiency and preventing rapid oxidation. The carrier comprises 70% aqua (water).

This carefully balanced formula ensures iron remains soluble and bioavailable across a broad soil pH range (4.5-9.0), making it highly effective even in alkaline or calcareous soils where conventional iron fertilizers fail.

2. How should I apply the Nano Iron fertilizer?

Nano iron offers flexible application methods tailored to crop and growing conditions:

Foliar Application (Recommended for rapid chlorosis correction):

• Dilute 2-3 liters in 500-750 liters water

• Apply early morning (6-8 AM) or late afternoon (4-6 PM) to avoid UV damage

• Target both leaf surfaces with low-pressure spraying

• Perform 1-2 split applications 10-14 days apart during vegetative growth

• Effects visible within 7-10 days

Soil Drench (For sustained nutrient availability):

• Integrate 2-3 liters per hectare with irrigation water

• Apply at early growth stages (4-6 leaf stage in cereals) or mid-season

• Target the rhizosphere (root zone) for maximum absorption

• Use with drip systems or hand-drenching near the stem base

• Optimal for perennial crops and fruit trees

Seed Treatment (For seedling vigor):

• Coat 5-10 ml per kg of seed with nano iron suspension

• Mix with crude sugar or gelatin coating slurry (1:10)

• Dry in shade and sow immediately

• Enhances root development and nodulation in legumes

Critical Timing Guidelines:

• Apply foliar sprays at first signs of interveinal chlorosis

• Soil drench applications should coincide with major nutrient uptake periods (tillering, pre-flowering, tuber set)

• For best results, use split applications rather than a single large dose

• Avoid application during extreme heat (>30°C) or within 48 hours of rain

3. What crops/plant types will benefit most from Nano Iron fertilization?

Nano iron delivers benefits across diverse crop categories, with particular advantage in iron-deficient scenarios:

Highly Responsive Crops:

• Legumes: Soybeans, chickpeas, lentils, alfalfa, peas, and fava beans—iron is critical for nodule formation and nitrogen fixation

• Cereals: Wheat, rice, barley, oats, and corn—especially in calcareous or high-pH soils prone to iron deficiency chlorosis (IDC)

• Tree Crops: Citrus, apples, grapes, almonds, pistachios, and olive trees—often grown in alkaline soils where conventional iron becomes unavailable

• High-Value Vegetables: Tomatoes, peppers, cucumbers, spinach, lettuce, and carrots—nano iron improves quality, color, and shelf life

• Fruit Crops: Strawberries, blueberries, raspberries—sensitive to iron deficiency; nano iron enhances fruit color and anthocyanin content

• Root and Tuber Crops: Potatoes, sugar beets—iron supports enzyme function during tuber/root development

• Oil Seeds: Canola, sunflower, peanuts—nano iron increases oil content and protein quality

Moderately Responsive Crops:

• Maize, sorghum, millet, sunflower, cotton

Specific Scenarios Requiring Nano Iron:

• Alkaline/Calcareous Soils (pH >7.5): Where iron becomes chemically fixed and unavailable to plants

• Over-limed Fields: Excessive lime application reduces iron solubility

• High-Organic-Matter Soils: Iron complexation with organic compounds can reduce plant availability

• Waterlogged Conditions: Some soils create anaerobic conditions that increase iron to toxic levels, requiring nano iron for precise, controlled delivery

• Seedling Production: Nurseries and tissue culture operations benefit from nano iron in propagation media

Geographic/Climatic Priority Regions:

• Mediterranean basin and subtropical regions with calcareous soils

• Semi-arid regions prone to iron deficiency chlorosis (IDC) in soybean, corn

• High-rainfall regions where iron leaching occurs

• Areas with groundwater high in bicarbonate (reducing iron availability)

• NPK and Macronutrient Fertilizers: Urea, ammonium nitrate, phosphate fertilizers—nano iron improves overall nutrient efficiency without antagonism

• Other Nano-Fertilizers: Nano zinc, nano boron, nano copper, nano phosphorus—no chemical interactions; tank-mixing is common practice

• Chelated Micronutrients: Zn-EDTA, Cu-EDTA, Mn-EDTA—nano iron does not displace or antagonize other chelated forms

Moderately Compatible (Requires Sequential Application):

• Broad-spectrum Fungicides: Carbendazim, thiram—apply nano iron 5-7 days before or after to prevent potential oxidative interactions

• Oxidizing Agents: Permanganate-based products—apply nano iron separately with 3-5 day intervals

• Synthetic Chelate-Heavy Formulations: Very high concentrations of Fe-EDDHA or similar chelates may show marginal antagonism; maintain 10:1 ratio of nano iron to synthetic chelates

Incompatible (Avoid Tank-Mixing):

• High-pH Alkaline Products (pH >9): Lime slurry, sodium hydroxide—reduces nano iron stability; apply sequentially with 7-10 day gap

• Strong Oxidizing Biocides: Chlorine-based disinfectants—denatures chitosan polymer; apply nano iron before biocide treatment

• Highly Acidic Formulations (pH <3): May hydrolyze gelatin encapsulation; dilute separately before application

• Heavy-Metal-Based Pesticides: Lead arsenate, mercury fungicides (banned in most regions)—potential bioaccumulation risk
