Growing vibrant, high-yield tomato plants requires more than sun and water—it demands a thoughtful fertilizer strategy. With tomato fertilizer options ranging from fast-acting liquids to long-lasting granules, gardeners and growers often wonder: Which form delivers the best results? This comprehensive guide explores the science and strategy behind liquid and granular tomato fertilizers, helping you decide which is right for your garden size, plant stage, and productivity goals.
How Liquid Tomato Fertilizer Works
Liquid tomato fertilizers are water-soluble nutrients applied directly to the soil or foliage. Their biggest advantage? Speed. These fertilizers deliver immediate nutrient availability, especially during critical growth stages like flowering and fruit set.
Key Benefits of Liquid Tomato Fertilizer:
- Fast absorption: Nutrients are quickly taken up through roots or leaves.
- Precise application: Suitable for fertigation and foliar sprays.
- Ideal for stressed or nutrient-deficient plants: Quick correction of imbalances.
One standout in this category is Ugarit 40-10-10 + TE, which supplies high nitrogen (40%) for robust vegetative growth while supporting phosphorus and potassium levels. When tomatoes are transitioning into flowering, Ugarit 10-10-40 + TE ensures potassium dominates the mix, enhancing fruit development and quality.
Biofast, a gel fertilizer with a 12-12-12 NPK ratio plus 24% humic and fulvic acid, offers balanced nutrition and improved root uptake through its organic complex. This is particularly useful in early to mid-season applications.

When to Use Granular Tomato Fertilizer
Granular tomato fertilizers release nutrients more slowly, offering extended feeding over weeks or months. They’re particularly useful for large plots, raised beds, or in regions with limited irrigation.
Scenarios Where Granular Fertilizer Excels:
- Pre-planting base nutrition: Builds soil fertility before transplanting.
- Long-term feeding: Ideal for sustained nutrient supply over time.
- Minimal maintenance: Fewer applications required compared to liquid forms.
Ugarit 10-0-5 + 70% Organic Matter is a standout granular option. With 10% nitrogen, 5% potassium, and an impressive 70% organic content (27% humic, 43% fulvic), it supports microbial activity, improves soil structure, and feeds plants consistently.
For potassium-heavy feeding late in the season, Ugarit K-T-S 25 (36% K?O, 25% SO?) provides strong fruit-finishing support.
Tomato Fertilizer Absorption Rates Compared
Nutrient absorption varies significantly between liquid and granular formulations, affecting how quickly plants respond to feeding.
| Fertilizer Type | Average Nutrient Uptake Speed | Ideal For |
|---|---|---|
| Liquid Fertilizer | 1–7 days | Foliar feeding, fertigation, quick fixes |
| Granular Fertilizer | 1–4 weeks | Pre-planting, base feeding, slow release |
Ugarit DKP (33% P?O?, 44% K?O) is a liquid formula designed for fast nutrient mobilization during flowering and fruit set, particularly effective in drip systems. For those needing sustained phosphorus support, Ugarit 0-52-34 provides excellent phosphorus-potassium balance in suspension form.

Cost Differences in Tomato Fertilizer Forms
Price plays a critical role in choosing a fertilizer, especially in commercial production or large-scale gardening. While liquid fertilizers offer precision and speed, they often come with higher per-unit costs due to their formulation and ease of application.
Cost Considerations:
- Liquid Fertilizers:
- Higher upfront cost.
- Require more frequent applications.
- Ideal for short-term results or small plots.
- Granular Fertilizers:
- More economical for large-scale applications.
- Lower labor costs due to fewer applications.
- Greater storage stability.
Despite the cost difference, product efficiency can offset the price. For instance, SULPHOMIN (45% nitrogen, 15% sulfur, 25% organic matter) delivers concentrated nutrients in a liquid form with enhanced uptake, meaning less product may be needed over time.
Tomato Fertilizer Form Selection by Garden Size
The size of your tomato-growing area influences not only how much fertilizer you need but also which form is more practical.
Small Gardens or Potted Plants:
- Opt for liquid fertilizers like Ugarit Strawberry (20-25 P-K) for precise feeding.
- Easy to mix and apply without waste.
Medium to Large Home Gardens:
- Combine both forms: Apply granular fertilizer like Ugarit 10-0-5 at transplanting and supplement with liquids like CALCIMAG (15% N, 22% CaO, 3% MgO) during flowering to prevent blossom end rot.
Commercial Fields:
- Granular fertilizers like Ugarit K-T-S 70 (36% K?O, 70% SO?) are ideal for base nutrition.
- Supplement with liquids through fertigation systems using Super DKP (30% P?O?, 60% K?O) during reproductive stages.

Micronutrient Support for Tomatoes
Beyond NPK, micronutrients are vital for fruit set, disease resistance, and quality. Tomatoes especially benefit from balanced secondary and trace nutrients.
Consider these micronutrient-rich solutions:
- SULFOMIX: Delivers essential micronutrients like Fe, Zn, Mg, Mn, Cu, B, and Mo in suspension form—ideal for preventing deficiencies during rapid growth.
- Ugarit Multi: Combines 30% K?O, 32% sulfur, and 10% calcium, reinforcing fruit firmness and shelf-life.
- Ugarit Beet and Ugarit Grapes: Formulated with balanced trace elements suitable for fruiting crops like tomatoes.
Integrating these products within a scheduled fertility program ensures your tomatoes receive complete nutrition.
Final Recommendations for Tomato Fertilizer Strategy
To build an effective fertilization plan for tomatoes, consider the following:
- Early Growth Stage: Apply Ugarit 27-27-27 + TE for balanced NPK to establish strong roots and foliage.
- Flowering Transition: Switch to Ugarit 10-10-40 + TE to increase potassium without sacrificing nitrogen.
- Fruit Set and Maturation: Use Ugarit 0-52-34 or Super DKP for high-phosphorus, high-potassium feeding.
- Ongoing Micronutrient Maintenance: Incorporate SULFOMIX and CALCIMAG as foliar sprays or soil drenches.
Conclusion
Choosing between liquid and granular tomato fertilizer depends on your garden’s needs, crop stage, and resources. Liquid forms offer speed and precision, ideal for responsive feeding. Granular fertilizers, on the other hand, deliver long-lasting results for larger or less frequently tended areas.
To optimize your tomato crop, consider integrating both forms into a tailored fertilization plan. Explore our full Yarafert-compatible fertilizer lineup, including Ugarit, Biofast, and SULFOMIX solutions, designed for maximum tomato performance.
