A crop can only perform as well as its roots allow. When soil is compacted, waterlogged, salty, or otherwise difficult, roots struggle to develop, and the whole plant slows down. Valagro Kendal Root is an advanced root biostimulant developed for exactly these situations. It works directly on the root system to help plants restart growth, form new roots, and regain vigour after root stress.
Kendal Root is formulated as an NK fertiliser suspension (9-0-9), so it also supplies nitrogen and water-soluble potassium along with its biostimulant action. It is applied through fertigation or, where recommended, through an overhead application that carries the solution down to the root zone. This page covers the composition, application rates, and practical use of Kendal Root.

Kendal Root is particularly useful when crops face conditions that limit normal root development, such as difficult soils or other root stress situations. It can be used across a wide range of crops, and the official recommendation covers fertigation for all crops, with overhead application indicated for vegetables and row crops.
| Situation | How Kendal Root Helps |
|---|---|
| Root stress or damage | Supports new root growth and faster recovery |
| Difficult or hostile soil conditions | Helps maintain root vigour and crop performance |
| Growth check or slow restart | Promotes a rapid vegetative restart |
| Important growth stages | Supports the root system when demand is high |
| Application Method | Recommendation |
|---|---|
| Fertigation: Vegetable and Fruit Crops | 5 L/ha every 7 days when crop stress is low; 20 L/ha every 20 days when crop stress is high |
| Overhead Application: Lettuce and Carrot | 5 L/ha every 7 days when crop stress is low; 20 L/ha every 20 days when crop stress is high |
| After Application | Use enough water to wet the root system thoroughly |
The overall application rate is 5-20 L per hectare, depending on the level of root damage and how often the product is applied. A lower, more frequent dose suits crops under mild stress, while a higher, less frequent dose is used where root stress is severe. Follow the current product label for the exact crop-specific rate, and do not apply a universal ml-per-litre dose unless the label specifies one.
What is Kendal Root used for?
Kendal Root is a root biostimulant used to support root development, root vigour, and plant recovery when crops face conditions that restrict normal root growth.
What is the recommended dose of Kendal Root?
The rate is generally 5-20 L per hectare depending on root stress and application frequency. Follow the current product label for the exact crop-specific rate.
Can Kendal Root be applied through drip irrigation?
Yes. Kendal Root is recommended for fertigation, which delivers it to the root zone through the irrigation system.
What is the NPK content of Kendal Root?
It is an NK fertiliser suspension with 9% nitrogen and 9% water-soluble potassium oxide (K₂O), and no phosphorus (9-0-9).
Which crops can Kendal Root be used on?
It can be used on a wide range of crops. Fertigation is recommended for all crops, and overhead application is indicated for vegetables and row crops such as lettuce and carrot.
