Libro 20-20-20 + TE is a 100% water-soluble fertilizer with a balanced formula of 20% nitrogen (N), 20% phosphorus (P₂O₅) and 20% potassium (K₂O), plus trace elements (TE). It is designed to provide balanced nutrition throughout the different growth stages, supporting vegetative growth and root development while keeping the major nutrients in balance within the plant.
Its low-pH (acidifying) formulation helps lower the alkalinity of the fertigation solution and improves nutrient availability, especially in alkaline water. It also helps reduce salt precipitation inside irrigation lines and improves system efficiency, making it a good choice for modern fertigation programs that depend on controlling irrigation-solution quality.
Key Features
- Balanced 20-20-20 NPK formula for complete plant nutrition.
- Low pH (acidifying effect) improves nutrient solubility and uptake efficiency.
- Helps reduce salt precipitation in irrigation lines and improves drip-system efficiency.
- Improves nutrient-use efficiency in alkaline, high-bicarbonate water.
- Contains micronutrients that support vital processes and metabolic efficiency.
- 100% water-soluble, suitable for fertigation and foliar spraying.

Directions for Use
- Foliar spray: 1–2 g per 1 liter of water (100–200 g per 100 liters of water).
- Spray until full wetting of the foliage.
- Repeat every 10–14 days depending on crop stage.

- Adjust the rate according to growth stage and crop condition.
Suitable Crops
- Vegetables (tomato, cucumber, pepper, eggplant).
- Field crops (potato, corn, beet).
- Fruit trees (date palm, citrus, grapes, other fruit trees).
- Greenhouses and modern irrigation systems.
Precautions
- Do not mix with calcium nitrate in the same tank to avoid precipitation.
- Avoid spraying during high temperatures or under direct sunlight.
- Do not exceed the recommended rates.
- Store in a cool, dry place away from moisture.
Orkida Tip
- The effect of Libro 20-20-20 is most noticeable in alkaline water or in systems with precipitation inside the lines. It is best used within an integrated fertilization program that controls the pH of the irrigation solution.
