Maximizing plant health while preventing damage through proper mixing techniques
Liquid fertilizer is one of the most effective tools for delivering essential nutrients directly to a plant’s root system or foliage. Its fast-acting nature, high solubility, and versatility make it a favorite among growers. But to achieve optimal results and prevent plant stress or burn, knowing how to correctly mix and dilute liquid fertilizer is crucial.
In this guide, we’ll walk you through everything you need to know—from reading product labels and calculating water ratios to container selection and environmental conditions that affect dilution. We’ll also show how Yarafert products like Biofast, Ugarit K-T-S 25, and CALCIMAG can be integrated safely into your fertilization routine.
How to Read Labels and Measure Liquid Fertilizer Correctly
Before mixing any liquid fertilizer, understanding the product label is essential. Each formula has different nutrient concentrations and recommended dilution rates.
Here’s how to read and apply label data accurately:
- Nutrient percentages: For example, SULPHOMIN contains 45% Nitrogen and 15% Sulfur. This means 100 ml delivers 45 grams of nitrogen—potent enough to require careful dilution.
- Application rate: Labels typically suggest ml per liter or per square meter. Products like Biofast, with balanced NPK (12-12-12) and high humic content, are often used at 1:100 or 1:200 dilutions for foliar application.
- Crop-specific notes: Some products, such as Ugarit Grapes, include tailored micronutrients (Cu: 1.5%, Zn: 0.5%) suitable for vineyards—read the fine print for timing and frequency.
Always shake the container well before use, and use calibrated measuring cups or syringes to avoid dosing errors.

Ideal Water Ratios for Common Liquid Fertilizers
Water-to-fertilizer ratios vary based on product concentration, crop type, and application method (soil drench vs. foliar spray). Overdiluting can reduce effectiveness, while underdiluting may burn plants.
Below are typical dilution ratios for key YaraFert products:
| Product | Application Type | Recommended Dilution |
|---|---|---|
| Biofast | Foliar / Drip | 5–10 ml per liter (1:100–1:200) |
| Ugarit K-T-S 25 | Drip irrigation | 2–5 ml per liter |
| CALCIMAG | Calcium booster | 3–6 ml per liter |
| Ugarit DKP | Flowering phase | 2–4 ml per liter |
| Super DKP | Fruit filling stage | 1–3 ml per liter |
| Ugarit Beet | Micronutrient mix | 2–3 ml per liter |
| Phosphoric Acid 85% | pH adjustment | 0.5–1 ml per liter |
Start with the lower end of the range during initial applications, especially for seedlings or newly transplanted crops.
What Containers Are Best for Mixing and Storing Liquid Fertilizer
The right container can make all the difference when it comes to safety, precision, and ease of use. Using inappropriate materials or poor mixing tools can compromise your results—or worse, degrade the fertilizer.
Key considerations when choosing containers:
- Material compatibility: Use plastic (HDPE) or stainless steel to prevent corrosion. Avoid metal containers with acidic products like Phosphoric Acid 85%.
- Graduated markings: Choose mixing containers with clear volume lines to measure both water and liquid fertilizer accurately.
- Dedicated sprayers: Use separate tanks for herbicides and liquid fertilizers to avoid contamination.
- Storage conditions: Keep diluted fertilizer in shaded, cool areas and always seal tightly. Most blends like Ugarit Cereal and Ugarit Strawberry are stable for 1–2 days post-mixing but lose efficacy if exposed to sunlight.
Never mix directly in irrigation lines without a bypass system or venturi injector to ensure even distribution.

Mixing Tips for Indoor vs. Outdoor Liquid Fertilizer Use
Indoor plants and outdoor crops have different nutrient uptake behaviors, water needs, and light exposure. This affects how you should mix and apply liquid fertilizer.
Here are some practical differences to consider:
- Indoor Use:
- Use more diluted solutions (1:200 or more) to prevent salt buildup.
- Products like Biofast, with its humic/fulvic acids, are great for potted plants as they improve soil health in small volumes.
- Apply with a small watering can or handheld sprayer.
- Outdoor Use:
- Slightly more concentrated mixes (1:100 to 1:150) can be used, depending on the crop.
- Use motorized or backpack sprayers for larger coverage areas.
- Acidic fertilizers like Sulforex 80 + S (80% sulfur) are best used outdoors due to strong odor and pH-lowering effects.
Adjust your watering frequency accordingly, especially in containers where excess salts can accumulate faster.

How Temperature and pH Affect Liquid Fertilizer Dilution
Environmental conditions such as temperature and water pH can greatly impact the solubility and uptake efficiency of liquid fertilizer.
Consider these key factors when preparing your solution:
- Water temperature: Cold water can slow solubility. Always mix in room-temperature water, especially with gel-based products like Biofast.
- pH sensitivity: Many nutrients are pH-sensitive. For instance:
- Calcium and magnesium from CALCIMAG are less available at low pH.
- Phosphorus from Ugarit DKP is most available at pH 6.0–6.5.
- Sulfur from Ugarit K-T-S 70 is most effective when the solution is slightly acidic (pH 5.5–6.5).
- Chemical compatibility: Mixing high-calcium fertilizers with acidic or phosphate-heavy products can cause precipitation. Use a jar test or mix sequentially.
Pro Tip: Use a digital pH meter to adjust your water before mixing, especially for foliar applications where leaf burn risk is higher.

Final Thoughts on Mixing Liquid Fertilizer Safely
Mixing and diluting liquid fertilizer properly is both a science and an art. When done right, it ensures your plants receive nutrients efficiently, without the risk of overfeeding or nutrient lockout. The process begins with understanding your fertilizer’s chemical profile, reading labels carefully, and adapting to your plant’s environment.
Products from YaraFert, such as Biofast, CALCIMAG, and Ugarit K-T-S 25, are formulated for high solubility and stable mixing—making them ideal for growers seeking both performance and safety. By following dilution guidelines, choosing the right containers, and adjusting for environmental factors, you can harness the full power of liquid fertilizer.
