+ROOT SOLID
Concentrated Solid Rooting Biostimulant for Faster Establishment and Stronger Crop Development
A vigorous and well-developed root system is essential for efficient nutrient uptake, balanced vegetative development and improved crop performance. +ROOT SOLID supplies key nutritional and physiological components that support root initiation, elongation and branching. Its high phosphorus content promotes energy-dependent processes involved in early development, while free amino acids provide readily available organic compounds that help sustain plant metabolism during establishment and recovery.
The formulation is suitable for both foliar and soil applications, although its main positioning is in root-zone treatments, substrates, nurseries, transplanting programmes and fertigation. By promoting root activity, +ROOT SOLID helps increase the plant’s capacity to explore the growing medium and absorb water and nutrients. It is especially recommended after transplanting, during crop establishment, when root development must be reactivated, and after environmental or agronomic stress.

Origin and Certifications
+ROOT SOLID is developed and marketed by Tangel Agro, a Spanish agricultural-input company focused on crop nutrition, biostimulation and bioprotection. The product is formulated as a concentrated solid containing mineral nutrients, free amino acids and root-development compounds.
The available technical datasheet does not specify a particular third-party certification, organic-input approval or international registration. Product registration, authorized uses and certification status should therefore be verified according to the legislation of the country in which the product will be marketed or applied.

- Improves root-zone activity and nutrient uptake capacity.
- Helps crops recover after adverse environmental conditions.
- Supports the development of stronger and more vigorous plants.
- Contributes to more balanced vegetative and reproductive growth.
- Helps improve the productive potential of the crop.
- Can be applied through substrates, root drenches, foliar sprays and drip irrigation.
- Is suitable for a wide range of horticultural, fruit, ornamental and field crops.
Key Benefits
Faster Crop Establishment
The product stimulates root development during the first stages of crop growth, helping seedlings and transplants establish more rapidly in the soil or growing medium.
More Absorbent Root Hairs
+ROOT SOLID promotes the formation of fine absorbent roots, increasing the active root surface available for water and nutrient uptake.
Improved Nutrient Acquisition
A larger and more active root system can explore a greater volume of soil or substrate, helping the crop access nutrients more efficiently.
Stronger Plants After Transplanting
Applied at transplanting or during the following weeks, the product supports root renewal and helps reduce the impact of transplant stress.
Root-Zone Reactivation After Stress
The formulation can be included in recovery programmes following heat, cold, drought, waterlogging, salinity or other conditions that reduce root activity.
Greater Crop Vigour
By strengthening the foundation of the plant, +ROOT SOLID supports more uniform vegetative development and greater resistance to adverse growing conditions.

Recommended Crops and Timing of Application
Vegetable and Horticultural Crops
Recommended for tomatoes, peppers, cucumbers, melons, watermelons, courgettes, aubergines, lettuce, brassicas, onions and other transplanted vegetables.
Apply during nursery development, at transplanting and throughout the first weeks after transplanting. It can also be used when root activity has been affected by low temperatures, excessive moisture, salinity or other stressful conditions.
Fruit Trees and Perennial Crops
Suitable for citrus, stone fruit, pome fruit, grapes, olives, avocado, mango and other perennial crops.
Apply at the beginning of active root-growth periods, after planting young trees, following periods of root stress or when increased nutrient uptake is required. Repeat two or three times according to crop condition and technical advice.
Berries
Recommended for strawberries, blueberries, raspberries, blackberries and other berry crops.
Apply after planting, at the beginning of vegetative activity, during root reactivation and after conditions that may restrict root development.
Field and Extensive Crops
Suitable for cereals, maize, rice, legumes, oilseeds, cotton and other annual field crops.
Apply during early establishment or through fertigation where available. Applications may be repeated at 10–15-day intervals during the initial development period.
Nursery and Ornamental Crops
Recommended for seedbeds, propagation trays, rooted cuttings, ornamental plants, flowers and container-grown crops.
Incorporate into the growing medium or apply as a root drench beginning from the early stages of seedling or cutting development.
Stress-Recovery Programmes
Apply after transplant shock, temperature stress, temporary drought, waterlogging, salinity, root damage or other conditions that reduce root activity. Root-zone applications are generally preferred when the objective is to reactivate the root system.
Compatibility and Application Recommendations
Dissolve the required quantity in a small volume of water before adding it to the application tank. Maintain agitation until the product is fully dissolved and apply the solution uniformly.
+ROOT SOLID may be combined with other products registered for the intended crop, but a small compatibility test should be carried out before preparing a full tank mixture. Avoid combining it with non-chelated calcium-based products unless compatibility has been previously confirmed.
For root applications, avoid excessive irrigation immediately after treatment, as this may move the product below the active root zone. Application equipment should be clean and properly calibrated.
FAQ
What is +ROOT SOLID used for?
+ROOT SOLID is used to stimulate root initiation, branching, elongation and absorbent root-hair formation. It is particularly useful during propagation, transplanting, early establishment and recovery after stress.
Can it be applied to all crops?
The product is recommended for a wide range of crops, including vegetables, fruit trees, berries, field crops, ornamentals and nursery plants. Always verify that the intended use is permitted under local regulations.
Is +ROOT SOLID applied through the soil or as a foliar spray?
It can be applied through both methods. Soil, root-drench and fertigation applications are especially suitable when the main objective is direct root stimulation. Foliar applications can complement post-transplant programmes.
When should it be applied after transplanting?
The first application can be made at transplanting or when root activity begins, generally one to five days later. Additional treatments may be applied during the following weeks.
How often can applications be repeated?
Newly transplanted crops may receive one or two repeat applications at weekly intervals. Annual crops can be treated every 10–15 days during establishment, while perennial crops may receive two or three applications during an active root-development period.
Can it be used in nursery trays?
Yes. Apply 100 g per 200 L of water once per week, beginning from the third week of seedling development. It may also be incorporated into growing media at 125–250 g per 100 kg of substrate.
Can it be applied through drip irrigation?
Yes. The recommended datasheet rate is 2 kg/ha per application, diluted in irrigation water. During post-transplant establishment, applications are recommended in the second, third and fourth weeks.
Can it be mixed with calcium products?
Mixing with non-chelated calcium-based products should be avoided unless a compatibility test has confirmed that the combination is physically and chemically stable.
Does the product replace the standard fertilization programme?
No. +ROOT SOLID should be integrated into a balanced crop nutrition and irrigation programme. Although it supplies nitrogen, phosphorus and amino acids, its main role is to stimulate root development and improve early crop establishment.
Why is phosphorus important in a rooting product?
Phosphorus is involved in energy transfer and several metabolic processes that are especially important during early plant growth. An adequate phosphorus supply supports the energy requirements associated with root initiation and development.
