MAGPI IN-FURROW STARTER NUTRITION
MagPi- In-Furrow Starter Nutrition for Potatoes, Arable & Vegetable Crops
MagPi In-Furrow Starter Nutrition Use:
MagPi is a high-availability liquid starter fertiliser developed as a source of phosphate, potassium and magnesium for use at planting or as an early foliar spray.
It is designed to introduce key nutrients from the earliest stages of crop growth and development, supporting root establishment, tuber initiation, canopy development, crop quality and yield. MagPi can be applied in-furrow, onto the seed tuber at planting, or as a foliar feed during the early stages of growth.
Key benefit:
Delivers early phosphate, potassium and magnesium for rooting and crop establishment
MagPi provides crops with direct access to three key nutrients required for early root growth, tuber development and strong canopy formation. Its high-availability formulation helps support crop development from the earliest stages, making it particularly useful for potatoes, arable and field vegetable crops.
Benefits:
- Provides direct access to phosphate, potassium and magnesium.
- Supports early root growth and crop establishment.
- Helps promote tuber development in potatoes.
- Supports strong canopy development.
- Can be applied in-furrow or directly onto the seed tuber at planting.
- Can also be applied as an early foliar feed.
- Suitable for all arable and field vegetable crops.
- Can be combined with Symposium microbial and fungi mix as part of a crop programme.
When and where to use:
MagPi can be used at planting as an in-furrow starter fertiliser, particularly in potatoes where early nutrient access is important for rooting and tuber development.
It can also be used as a foliar spray from the earliest stages of crop growth and development, where phosphate, potassium and magnesium support is required. Always use sufficient water for good coverage.
Crops:
Potatoes, all arable crops and field vegetable crops.
Pack Size:
