+ROOT SOLID is a concentrated solid rooting biostimulant designed to promote root development and early crop establishment. Its formulation combines 35% phosphorus, free amino acids and specific rooting compounds including IBA and naphthyacetic acid.
The product can be applied foliarly or directly to the root zone. It is intended to support nutrient flow from the soil solution to the plant, root-hair formation, crop vigor and recovery after stressful conditions, while helping establish the root system required for productive crop development.

+ROOT SOLID combines a high concentration of rapidly assimilable phosphorus with free amino acids and two specific rooting compounds: IBA and naphthyacetic acid. The formulation is designed to favor root-system development during early crop stages and after transplanting.
The source links a well-developed root system with proper vascular-tissue formation and productive potential. It also describes the product as useful at the beginning of plant activity and during stress situations where root-zone reinforcement is required.
Application Guidance: For newly transplanted seedlings, apply when root activity begins, approximately 1-5 days after transplanting. For best results, the source recommends repeating once or twice at weekly intervals. For annual crops during establishment, applications at 10-15 day intervals are suggested; for perennial crops, apply when root development starts or during fruiting, repeating 2-3 times where appropriate.
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Substrate or substrate for trays | During substrate preparation | 125-250 g per 100 kg of substrate | Dissolve in enough water to humidify 100 kg of substrate. Use the lower dose below 20°C and the higher dose above 20°C. |
| Nursery beds and trays | Starting in the third week of seedling development | 100 g per 200 L of water | Apply once a week. |
| Transplants | At transplanting and/or one week after transplanting | 100 g/100 L at transplanting · 400 g/100 L one week later | For the second treatment, direct the solution to the base of the plant. |
| Crops | Timing | Dose |
|---|---|---|
| Transplanted crops | Second and third weeks after transplanting | 0.5-1 kg/ha |
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Transplanted crops | Second, third and fourth weeks after transplanting | 2 kg/ha | Dilute the product in irrigation water and apply by drip irrigation. |
+ROOT SOLID is intended for insufficient root development, transplant establishment and situations where crops require root-zone reinforcement. The source specifically positions it for early plant activity and stressful conditions where recovery and reactivation of the root system are needed.
The source recommends mixing only with registered products authorized for the crop and carrying out a compatibility test beforehand. Avoid mixing with non-chelated calcium-based products.
