High-Concentration Nitrogen for Maximum Crop Yields

Urea 46% Nitrogen Fertilizer is the world’s most widely used solid nitrogen fertilizer. Containing 46% pure nitrogen, it offers the highest nutrient concentration of any dry nitrogen source on the market. Designed to accelerate vegetative growth, deepen leaf greenness, and significantly improve harvest yields, Urea 46% is the go-to nutrient solution for commercial farmers, green keepers, and home gardeners alike.

Whether you are cultivating broadacre grains, high-value fruit and vegetable crops, or maintaining golf course turf, Urea 46% provides an economical, fast-acting, and highly versatile feeding option.

Key Benefits of Urea 46% Nitrogen Fertilizer

• Highest Nitrogen Concentration: At 46% N by weight, you get double the nitrogen density of traditional options like Ammonium Sulfate. This drastically lowers transport, handling, and storage costs per acre.

• Promotes Rapid Foliage Growth: Essential for chlorophyll production and protein synthesis, driving robust vegetative growth, dark green leaf development, and strong stems.

• Fully Water-Soluble: Dissolves rapidly in moist soil or water systems, converting into plant-available ammonium and nitrate forms for rapid root uptake.

• Versatile Application Methods: Suitable for broadcast spreading, side-dressing, foliar spraying, or drip fertigation.

• Cost-Effective Efficiency: Delivers more active units of nitrogen per dollar spent, optimizing fertilizer ROI for high-acreage agricultural operations.

Guaranteed Technical Specifications: Urea 46% Nitrogen Fertilizer

Recommended Applications & Target Crops

Urea 46% is suitable for virtually all crop types and soil profiles. It performs exceptionally well when incorporated into the soil prior to planting or during key vegetative growth stages.

• Field Crops & Grains: Wheat, Corn/Maize, Rice, Barley, Oats, Sorghum

• Cash & Industrial Crops: Cotton, Sugarcane, Canola, Soybeans

• Vegetables & Root Crops: Tomatoes, Potatoes, Onions, Leafy Greens, Brassicas

• Orchards & Vineyards: Citrus, Apples, Grapes, Fruit Trees

• Turf & Lawn Care: Pastures, Golf Courses, Commercial Landscaping

Application Best Practices & Handling: Urea 46% Nitrogen Fertilizer

Pro Tip to Prevent Nitrogen Loss: Because surface-applied urea can lose nitrogen through ammonia volatilization (gaseous loss), it should ideally be worked into the soil (tilled/incorporated) or irrigated immediately after broadcast application.

1. Soil Incorporation: Apply prior to sowing or side-dress along crop rows and incorporate 2–3 inches into the soil.

2. Irrigation/Fertigation: Dissolve completely in irrigation water for drip or sprinkler delivery straight to the root zone.

3. Foliar Spray: Use a low-concentration solution ($\le 1–2\%$) to prevent leaf scorching during critical growth boosts.

4. Storage: Store in a cool, dry, well-ventilated warehouse in sealed bags to protect against moisture absorption (hygroscopic nature).

Frequently Asked Questions (FAQ)

What does “46-0-0” mean on a fertilizer bag?

The numbers represent the N-P-K ratio (Nitrogen–Phosphorus–Potassium). 46-0-0 means the product contains 46% Nitrogen, 0% Phosphorus, and 0% Potassium by weight.

Is Urea 46% safe for seed placement?

Direct seed contact should be avoided. High concentrations of urea near seeds can cause salt injury or damage germinating roots due to temporary localized ammonia release. Place the fertilizer 2–3 inches to the side and below the seed row.

What is the difference between Granular and Prilled Urea?

• Granular Urea: Features larger, harder particles (2–4 mm) designed for heavy agricultural equipment and bulk soil broadcasting.

• Prilled Urea: Features smaller, softer spheres (0.8–2.0 mm) that dissolve faster, making them ideal for foliar sprays, quick solution mixing, and liquid fertigation.

Recommended application rates for Urea 46% (NPK 46-0-0) vary depending on target crop needs, soil baseline nitrogen, and crop stage.

Because Urea 46% is so concentrated (46 lbs of pure nitrogen per 100 lbs of product), calculations must account for both total actual Nitrogen (N) required and the gross weight of Urea applied.

Quick Reference Application Rates

Detailed Application Guidelines by Crop : Urea 46% Nitrogen Fertilizer

1. Corn (Maize)

Corn requires heavy nitrogen inputs during rapid vegetative expansion.

• Calculation: To supply 150 lbs of actual N per acre:

  $$\text{Required Urea} = \frac{150 \text{ lbs N}}{0.46} \approx 326 \text{ lbs Urea/acre}$$

• Strategy: Avoid applying all 320+ lbs at once to prevent root burn and leaching. Band a smaller portion at planting, then side-dress the bulk when plants reach knee-high height (V4–V6 stage).

2. Wheat

Wheat nitrogen demands spike right around the tillering and stem elongation phases.

• Calculation: To supply 90 lbs of actual N per acre:

  $$\text{Required Urea} = \frac{90 \text{ lbs N}}{0.46} \approx 195 \text{ lbs Urea/acre}$$

• Strategy: Broadcast early in the spring when green-up begins. If applying on top of dry soil, incorporate with light tillage or time the application right before a expected light rain ($\ge 0.5$ inches) to lock in the nitrogen.

3. Lawn Care & Turf Management ; Urea 46% Nitrogen Fertilizer

Turfgrass requires lower, steady amounts of nitrogen to avoid excessive leaf growth and burning.

• Calculation: For a standard 1 lb of N per 1,000 sq ft rate:

  $$\text{Required Urea} = \frac{1 \text{ lb N}}{0.46} \approx 2.17 \text{ lbs Urea / 1,000 sq ft}$$

• Strategy: Always water the lawn immediately after application with roughly 0.25 to 0.5 inches of water to wash granules into the root zone and prevent leaf blade scorch.

Crucial Rule for Application:

Never place high rates of Urea 46% in direct contact with seed rows. High local concentrations of ammonia released during urea hydrolysis can severely injure germinating seeds and root tips. Keep banded fertilizer at least 2 inches beside and 2 inches below the seed line ($2 \times 2$ placement).
