Nitrogen is the lifeblood of plant growth, fueling lush foliage, robust stems, and bountiful yields—and urea nitrogen fertilizer stands out as a top choice for delivering this essential nutrient. With its high nitrogen concentration and neutral nature, it’s a versatile option for a wide range of crops. SHIJIAZHUANG HAN HAO TRADE CO.,LTD., a leader in agricultural fertilizers with a 70,000-square-meter factory and advanced production lines, understands its value. Their product lineup includes high-quality urea, part of their 600,000 MT annual capacity, ensuring farmers have access to reliable urea nitrogen fertiliser options. This article explores the best crops to pair with urea nitrogen fertilizer, highlighting how this nutrient powerhouse supports their growth and productivity.

Grains Thriving with Urea Nitrogen Fertilizer 46 0 0

1. Wheat’s Nitrogen Hunger: Wheat is a heavy nitrogen feeder, especially during its vegetative growth stage. Urea nitrogen fertilizer 46 0 0 —with its 46% nitrogen content—delivers the high dose needed to promote tillering (the formation of multiple stems) and leaf development. Applying it at planting and again when the crop reaches knee height results in thicker stands and plumper grains, making it a staple for wheat farmers.
2. Corn’s Rapid Growth Boost: Corn grows quickly, demanding a steady supply of nitrogen to support its tall stalks and large leaves. Urea nitrogen fertilizer provides this in spades, with its slow-release properties ensuring nitrogen is available during both the vegetative and reproductive phases. Farmers often side-dress corn with urea nitrogen fertiliser when the plants are 12–18 inches tall, fueling the growth spurt that leads to full ears.
3. Rice’s Flood-Tolerant Nutrition: Rice fields are often flooded, but urea nitrogen fertilizer holds up well in these conditions when applied correctly. Its neutral pH prevents soil acidification, a common issue in waterlogged environments. Applying it before flooding or as a top-dress during the tillering stage helps rice plants develop strong root systems and abundant panicles, crucial for high yields.

Vegetables Benefiting from Urea Nitrogen Fertiliser

• Leafy Greens’ Lush Growth: Spinach, lettuce, and kale thrive on nitrogen, which is essential for producing tender, vibrant leaves. Urea nitrogen fertiliser is ideal here, as its high nitrogen content promotes rapid leaf growth without adding excess phosphorus or potassium—nutrients that leafy greens need in smaller amounts. A light application every 2–3 weeks keeps these vegetables looking fresh and tasting great.
• Tomatoes’ Balanced Development: While tomatoes need phosphorus for fruit development, they also require nitrogen for strong vines and healthy foliage. Urea nitrogen fertilizer applied early in the season (before flowering) supports vine growth, ensuring the plants can bear the weight of ripening fruit. Too much nitrogen late in the season can lead to excessive leaf growth at the expense of fruit, so timing is key—making urea’s controlled release a advantage.
• Cucumbers’ Vigorous Vines: Cucumbers are known for their fast-growing vines, which rely heavily on nitrogen. Urea nitrogen fertilizer 46 0 0 provides the boost needed to keep vines spreading and producing new flowers (and thus more cucumbers). Applying it when vines start to run ensures they have the energy to reach their full potential, resulting in a longer harvest period.

Best Practices for Using Urea Nitrogen Fertilizer

• Avoiding Volatilization Loss: Urea nitrogen fertilizer can lose nitrogen to the air if left on the soil surface, especially in warm, moist conditions. To prevent this, incorporate it into the soil within 24–48 hours of application, either by tilling or watering it in. This ensures the nitrogen is trapped in the soil where plants can access it.
• Balancing with Other Nutrients: While urea is rich in nitrogen, crops need a full range of nutrients to thrive. Pair urea nitrogen fertiliser with phosphorus and potassium sources (like SOP or DAP) based on soil tests. For example, corn benefits from a mix of urea and phosphorus at planting, while leafy greens may only need urea and a small amount of potassium.
• Considering Crop Rotations: Urea’s neutral nature and lack of harmful residues (as noted, long-term use has no adverse effects) make it perfect for crop rotations. Fields planted with nitrogen-loving crops like wheat can be followed by legumes (which fix their own nitrogen) with no soil damage, allowing farmers to maintain fertility across seasons.

Urea Nitrogen Fertilizer FAQS

Is Urea Nitrogen Fertilizer Safe for Long-Term Use?

Yes, urea nitrogen fertilizer is safe for long-term use. As a neutral-acting fertilizer, it leaves no harmful residues in the soil, even with repeated applications. This makes it a reliable choice for sustainable farming systems where soil health is a priority.

Can Urea Nitrogen Fertilizer 46 0 0 Be Used on All Crops?

While urea nitrogen fertilizer 46 0 0 works well for many crops, it’s best suited for those with high nitrogen needs, like grains and leafy greens. Crops that prefer lower nitrogen (such as root vegetables like carrots) may benefit from lighter applications to avoid excessive leaf growth at the expense of roots.

How Much Urea Nitrogen Fertiliser Should Be Applied per Acre?

Application rates vary by crop: wheat and corn typically need 80–120 pounds of urea nitrogen fertiliser per acre, while leafy greens require 40–60 pounds. Always follow soil test recommendations to avoid over-application, which can lead to nutrient runoff.

When Is the Worst Time to Apply Urea Nitrogen Fertilizer?

Avoid applying urea nitrogen fertilizer during heavy rain or when the soil is waterlogged (unless planting rice). This can cause nitrogen to leach into groundwater. Also, applying in extremely hot, dry weather increases volatilization loss—early morning or late afternoon applications are better.
