For gardeners seeking optimal plant growth, choosing between urea fertilizer and compost can feel like comparing speed to sustainability. Both options enhance soil fertility—but in vastly different ways. This guide explores the nutrient profile, application speed, soil impact, and long-term effects of urea fertilizer versus compost, helping you make the most informed decision for your garden.
Let’s break down how urea fertilizer compares to compost across five essential gardening metrics.
Nutrient Availability in Urea Fertilizer vs. Compost
Urea fertilizer (CO(NH?)?) is one of the most concentrated sources of nitrogen (N), containing about 46% N, making it a powerful tool for nitrogen-deficient soils. Nitrogen is a critical macronutrient that supports leaf and stem development.
Compost, in contrast, offers a broader but less concentrated nutrient mix. It typically contains:
- 1-3% nitrogen,
- Trace phosphorus and potassium,
- High levels of organic matter, improving soil texture and microbial activity.
Here’s a side-by-side comparison of nutrient composition:
| Fertilizer Type | Nitrogen (%) | Phosphorus (%) | Potassium (%) | Organic Matter |
|---|---|---|---|---|
| Urea Fertilizer | 46% | 0% | 0% | 0% |
| Compost | 1–3% | 0.5–1% | 0.5–1% | High |
To increase phosphorus and potassium availability alongside urea, you can use Ugarit 10-10-40 + TE or Ugarit 27-27-27 + TE from the Yarafert line. These formulations balance nitrogen with other macronutrients for complete plant nutrition.
Speed of Results Using Urea Fertilizer
Urea fertilizer acts fast. Once hydrolyzed by the enzyme urease in soil, it converts into ammonium (NH??) and then nitrate (NO??), forms plants can readily absorb. This makes it ideal for:
- Rapid green-up,
- Correcting acute deficiencies,
- Encouraging lush vegetative growth in early stages.
Compost, however, releases nutrients slowly as microbes break down organic matter. While beneficial for long-term fertility, it won’t deliver the same immediate boost that urea fertilizer can provide.
Tip: When immediate growth is needed, combine urea with SULPHOMIN (N 45%, S 15%, Organic Matter 25%) to enhance nitrogen efficiency while maintaining organic content.

Urea Fertilizer vs. Compost for Soil Health
Although urea fertilizer delivers nutrients quickly, it doesn’t contribute organic matter or improve soil structure. Over time, repeated use without organic amendments can degrade soil biology and pH levels.
In contrast, compost enhances:
- Soil water retention,
- Microbial activity,
- Aggregate stability.
That said, this isn’t a binary choice. Gardeners can pair urea fertilizer with Ugarit 10-0-5 + 70% Organic Matter to combine nitrogen efficiency with humic and fulvic acids that promote microbial health.
Here’s how they stack up on soil health metrics:
| Parameter | Urea Fertilizer | Compost |
|---|---|---|
| Organic Matter | ? | ? |
| Microbial Support | ? | ? |
| Soil Structure | Neutral | Improved |
| pH Impact | Acidifying | Neutral to Alkaline |
If your soil needs both nitrogen and structural enhancement, consider products like Biofast (NPK 12-12-12, with 24% humic and fulvic acid), which bridge the gap between synthetic and organic options.
Cost and Effort Comparison of Urea Fertilizer and Compost
Cost and application effort are significant factors in fertilizer choice:
- Urea fertilizer is lightweight, compact, and inexpensive per nutrient unit. It’s easy to store, apply, and dose precisely.
- Compost requires more labor (turning, hauling, spreading) and space to process or store. While cheaper if homemade, bulk compost can become costly for large gardens.
Here’s a quick breakdown:
| Factor | Urea Fertilizer | Compost |
|---|---|---|
| Price per kg of N | Low | High |
| Application Time | Low | High |
| Storage Space | Minimal | High |
| Odor/Attractants | None | Possible (if unmanaged) |
To minimize leaching and volatilization of urea, consider combining it with CALCIMAG (N 15%, Ca 22%, MgO 3%) or Sulforex 80 + S, which stabilize nitrogen while enriching with sulfur and calcium.

Long-Term Benefits of Urea Fertilizer in Gardens
Though compost improves long-term soil health, urea fertilizer supports consistent nutrient supply year over year—especially when applied strategically.
Key long-term benefits of using urea fertilizer include:
- Predictable nitrogen availability for seasonal crop cycles,
- Controlled-release potential when stabilized with organic matter or sulfur,
- High return on investment due to concentrated nutrient content.
To make the most of urea over the long term:
- Rotate with organic amendments to maintain soil health,
- Use integrated solutions like Ugarit Cereal (N 15%, Cu 2%) for cereal crops, or Ugarit Grapes for micronutrient balance in vineyards.
Pro tip: Apply Ugarit Multi (K 30%, S 32%, Ca 10%) post-urea application to fortify plant resistance and boost flowering and fruiting.
Final Verdict: Urea Fertilizer or Compost?
Choosing between urea fertilizer and compost depends on your garden’s current needs:
Choose urea fertilizer if:
- You need fast, targeted nitrogen correction.
- You grow high-demand crops like corn, tomatoes, or leafy greens.
- You want a cost-effective way to boost growth during key stages.
Choose compost if:
- You aim to improve long-term soil health.
- You practice organic gardening.
- Your soil is sandy, depleted, or microbiologically inactive.
Or better yet—use both. A hybrid strategy offers the best of both worlds, especially when you combine urea fertilizer with Yarafert solutions like SULFOMIX (with micronutrients and 11% sulfur) or Ugarit 25-25-25 + TE for balanced NPK delivery.
