Urea fertilizer (46-0-0) is the most concentrated solid nitrogen fertilizer available, containing 46% nitrogen by weight. When applied to soil, urea undergoes hydrolysis through the enzyme urease, converting to ammonium carbonate and then to plant-available ammonium and nitrate forms. This transformation typically occurs within 2-4 days under optimal conditions (moist soil, temperatures between 50-85°F). The high nitrogen content makes urea extremely efficient for promoting vegetative growth, chlorophyll production, and protein synthesis in plants.

To minimize nitrogen loss through volatilization (conversion to ammonia gas), follow these best practices:

• Incorporate quickly: Work urea into soil within 24-48 hours of application
• Apply before rain: Time applications before expected rainfall (0.5 inches or more)
• Irrigate after application: Apply at least 0.5 inches of water if rain isn't expected
• Avoid hot, windy days: High temperatures and wind increase volatilization
• Consider urease inhibitors: These can reduce losses by 40-50% if incorporation isn't possible
• Split applications: Multiple smaller applications are more efficient than single large doses

Timing varies by crop and climate, but general guidelines include:

• Cool-season grasses: Early spring (when soil reaches 55°F) and fall
• Warm-season grasses: Late spring through summer during active growth
• Vegetables: At planting and again at specific growth stages (e.g., corn at knee-high)
• Trees: Early spring before bud break for deciduous trees
• Field crops: Pre-plant incorporation or side-dress during rapid growth phases

Avoid applying during drought stress or when plants are dormant, as this increases the risk of nitrogen loss and potential plant damage.

Yes, urea can cause fertilizer burn if improperly applied due to its high salt index and rapid conversion to ammonia. Prevention strategies include:

• Proper dilution: Never exceed recommended rates; when in doubt, use less
• Keep away from seeds: Place urea at least 2 inches away from seeds or transplants
• Water immediately: Irrigate after application to move urea into the soil
• Avoid foliar contact: Unless specifically diluted for foliar feeding (0.5-2% solution)
• Don't apply to wet foliage: This concentrates the fertilizer and increases burn risk
• Use split applications: Divide total amount into 2-3 smaller applications

No, synthetic urea is not approved for certified organic production. Urea is manufactured through an industrial process combining ammonia and carbon dioxide under high pressure and temperature. Organic gardeners seeking nitrogen sources should consider:

• Blood meal (12-0-0)
• Feather meal (12-0-0)
• Fish emulsion (5-1-1)
• Composted manure (varies)
• Alfalfa meal (2.5-0.5-2.5)

However, urea remains an excellent choice for conventional gardening due to its high efficiency, cost-effectiveness, and rapid results.
