Diammonium Phosphate (DAP) stands as a premier nitrogen-phosphorus fertilizer, essential for boosting crop yields and soil fertility in modern agriculture. DAP, chemically (NH4)2HPO4, delivers 18% nitrogen and 46% phosphorus (P2O5), making it highly concentrated and soluble for rapid nutrient release. Granules measure 2-4 mm, ideal for broadcasting, side-dressing, or fertigation across diverse soils. Produced by reacting ammonia with phosphoric acid, it creates an alkaline zone around granules while supporting long-term soil acidification.
DAP promotes robust root development, enhances flowering and fruiting, and improves nutrient uptake, leading to higher yields in field crops. Its ammonium nitrogen resists leaching, offering cost-effective dual nutrition, while slightly acidic properties adjust alkaline soils. Versatile blending with traces or other fertilizers customizes formulations for specific needs.
Urea N46% stands as the world's leading nitrogen fertilizer, supplying 46% nitrogen to drive vigorous crop growth and boost yields across diverse soils. Urea N46%, or carbamide, features white prilled or granular forms (1-4 mm size, ≥95% uniformity) with low moisture (≤0.5%) and biuret (≤1.0%) for safe handling. Highly soluble in water, it hydrolyzes to ammonium in soil, then nitrate, with a neutral pH (8.0-8.5) and melting point of 132°C. Available in granular (slow-release) and prilled (quick-dissolving) variants for broad application flexibility.
It accelerates vegetative growth in cereals, vegetables, and fruits while improving protein content and soil fertility at lower transport costs per nitrogen unit. Cost-effective and versatile, urea enhances chlorophyll production and resists leaching when incorporated properly.
Apply 40-300 kg/ha via broadcasting, banding, or foliar spray for rice, wheat, corn, sugarcane, cotton, and horticulture. Industrial uses include animal feed additives and resin production.
NPK fertilizers provide balanced nutrition through nitrogen (N), phosphorus (P), and potassium (K) in customizable ratios, driving superior crop yields and soil vitality in modern farming. Available in ratios like 10-10-10, 20-10-10, or 15-15-15, NPK blends granular or water-soluble forms for tailored nutrient delivery. Nitrogen fuels vegetative growth, phosphorus builds roots and flowers, while potassium enhances disease resistance and water regulation. Granules (2-4 mm) ensure even spreading, with high solubility for quick uptake.
These fertilizers boost chlorophyll production, root strength, and fruit quality, correcting soil deficiencies for 20-30% higher yields. Versatile across crops, they improve stress tolerance and sustain long-term fertility when soil-tested.
Ideal for cereals (rice, wheat), vegetables (tomatoes, potatoes), fruits (citrus, grapes), and cash crops (cotton, sugarcane) at 100-400 kg/ha. Apply basal, top-dress, or via fertigation; common ratios suit growth stages.
Ammonium Nitrate N34 delivers 34% nitrogen in balanced ammonium and nitrate forms, making it a stable, fast-acting fertilizer for early-season crop boosts on alkaline soils. This granular fertilizer (95% particles 1-4 mm) features pH 6.0-7.2, low moisture (max 0.2-0.5%), and high granule strength (>6 MPa) for easy spreading and storage. Equal parts ammoniacal (17%) and nitrate (17%) nitrogen ensure quick uptake without rapid volatilization, unlike urea.
It promotes rapid vegetative growth, increases protein/oil content in grains, and acidifies soils over time, ideal for pH >7 conditions. More stable than higher-N options, it resists leaching and suits fertigation or broadcasting.
Best for cereals (wheat, barley, corn), potatoes, sugar beets, soybeans, and grasses at 100-300 kg/ha in spring or post-harvest. Avoid acidic soils; incorporate immediately to maximize efficiency.
Sulphur serves as an essential secondary nutrient in agriculture, correcting deficiencies to enhance crop quality, soil health, and nitrogen efficiency. Elemental sulphur (S 90-99%) arrives in prilled, granular, or powdered forms (1-5 mm), oxidizing slowly in soil via bacteria to sulphate for plant uptake. Neutral pH initially, it acidifies alkaline soils (pH >7.5) over 4-8 weeks, with low moisture (<0.5%) ensuring storage stability.
Sulphur boosts protein/oil synthesis, chlorophyll formation, and disease resistance (e.g., powdery mildew), while improving N use efficiency and drought tolerance. It unlocks phosphorus/iron in high-pH soils, reduces salinity, and elevates crop market value through better flavor and milling quality.
Apply 20-50 kg/ha basal for oilseeds (mustard), pulses, crucifers (rapeseed), and cereals, or blend into NPK for uniform delivery. Best in sandy, low-organic soils; incorporate 10-15 cm deep with irrigation to activate microbes.
Muriate of Potash (MOP), also known as Potassium Chloride (KCl), supplies 60% K₂O to strengthen crops against stress, enhance quality, and optimize water use in potassium-deficient soils. MOP appears as pink or white granules (2-4 mm, ≥95% uniformity) with moisture below 0.5% and high water solubility for rapid root uptake. Neutral in pH, it integrates easily into blends like NPK or SSP, supporting large-scale farming with low transport costs per nutrient unit.
Potassium from MOP builds robust stems, boosts disease resistance via thicker cell walls, and improves fruit color, flavor, and shelf life. It enhances drought tolerance by regulating water loss and pairs effectively with nitrogen for higher yields in saline or sandy soils.
Widely used for sugarcane, potatoes, cotton, soybeans, fruits, vegetables, and pastures at 50-200 kg/ha via broadcasting or banding. Avoid chloride-sensitive crops like tobacco; ideal for blending in basal or top-dressing.
Monopotassium Phosphate (MKP) delivers high phosphorus (52% P₂O₅) and potassium (34% K₂O) in a fully water-soluble, chlorine-free form, ideal for fertigation and foliar use during critical growth phases. MKP (KH₂PO₄), labeled 0-52-34, dissolves completely with neutral pH (4.5-5), low salt index, and no sodium or heavy metals, preventing leaf burn. Fine powder or crystals suit precise drip systems, blending seamlessly with pesticides for efficient nutrient delivery.
It accelerates root/shoot development, boosts flowering/fruit set, enhances sugar content, and builds disease resistance without excess nitrogen. Perfect for high-value crops, MKP improves quality and yield while maintaining soil balance across pH ranges.
Apply 1-3 kg/acre foliar (1-2% solution) or 10-20 kg/acre fertigation during transplanting to fruiting for tomatoes, peppers, bananas, citrus, and grapes. Repeat every 7-14 days; safe for hydroponics at 100-175 kg/1000L stock.
Monoammonium Phosphate (MAP) provides 12% nitrogen and 61% P₂O₅ in a low-pH, water-soluble form, ideal for starter fertilizers on alkaline soils and early root development. MAP (NH₄H₂PO₄), typically 12-61-0, features granules 2-5 mm (≥95%) with pH 4.0-5.0, moisture ≤0.3%, and high solubility (370 g/L at 20°C) for rapid nutrient release. Its ammoniacal nitrogen enhances phosphorus uptake without volatilization risks, unlike urea.
Lowers soil pH around roots for better nutrient access in calcareous soils, promotes strong seedlings, and boosts tillering/yields by 10-15% in cereals. Chloride-free and compatible with most blends (avoid Ca/Mg), it suits fertigation without equipment corrosion.
Basal application at 100-200 kg/ha for wheat, corn, soybeans, and vegetables; also foliar (0.5-1%) or drip for high-P needs during establishment. Best on pH >7.5 soils; split doses prevent fixation.
Ammonium Sulphate fertilizer combines 21% nitrogen and 24% sulphur to acidify alkaline soils, enhance protein synthesis, and support lush crop growth in sulphur-deficient regions. Chemically (NH₄)₂SO₄, it forms white crystalline granules (2-4 mm, ≥95% uniformity) with high water solubility (750 g/L) and solution pH of 5-6 for rapid nutrient availability. Moisture stays below 1.0% max, ensuring stability during storage and transport.
Provides quick-release ammonium nitrogen resistant to leaching, while sulphur boosts chlorophyll, oil content, and disease resistance in crops like rice and brassicas. Ideal for correcting soil pH >7.5, it improves N efficiency and nutrient uptake without chloride risks.
Apply 100-250 kg/ha basal or top-dress for paddy, wheat, tea, cotton, and vegetables; blends well with P/K fertilizers. Incorporate into soil for best results in sandy or low-organic matter fields.
