Potatoes
Fortified organic fertilizers that reduce inputs while improving soil health and nutrient balance.
Formulated for consistent tuber quality
Consistent grades and maximum pack-out start with a living soil. Atlas fertilizers combine organic carbon with balanced nutrients to stimulate soil biology and strengthen root growth from planting through bulking. The result is better size uniformity, and longer shelf-life. All while building soil structure that supports healthier rotations season after season.

Our Potato Crop Fertilizers
For Potato Growers
Ghwamis is a budget-friendly basal fertilizer designed to improve soil condition while supporting the early demands of a potato crop. It helps rebuild the soil environment from the ground up, giving young plants a better foundation for root development, early vigour, and more even establishment.
Well suited to new lands or lower-input programmes where restoring soil productivity matters as much as feeding the crop.
- Farmers notice: stronger root development and more even emergence
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
Super-VEG is a versatile fertilizer suited to the demands of a potato crop, whether used as a strong upfront feed or as the basal foundation of a broader programme. Its balanced formula supplies the essential nutrients needed to support establishment, steady canopy development, and uniform tuber production through the season.
It is especially useful where growers want a reliable base that carries the crop well while supporting both yield potential and marketable quality.
- Farmers notice: stronger canopy growth and more even tuber development
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
2.3.4(18) is a balanced NPK fertilizer that performs especially well in potato programmes where a stronger potassium weighting is needed to support yield and tuber quality. The nutrient balance also improves crop resilience throughout the season.
Whether used as a standard basal or applied at higher volumes in more intensive programmes, it gives potatoes a reliable foundation of essential nutrients.
- Farmers notice: better tuber bulking and more even sizing
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
Atlas 5.1.5(20) is an all-round biological fertilizer that has been used for years in potato programmes as a reliable once-off basal application. It provides a solid foundation of nutrients to carry the crop through establishment and early development, making it a practical option for growers who want a simple programme.
With a strong enough application upfront, very little else is needed to keep the crop moving well.
- Farmers notice: firmer, better-sized potatoes that hold up well in storage
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
Designed as an all-round stimulator, 3.1.2(18) helps meet seasonal phosphate requirements while also supporting vegetative growth and the early stages of tuber initiation in potatoes. Its balanced blend keeps the crop growing actively through key development stages, helping build the foundation for a healthier, more productive stand.
- Farmers notice: strong growth and even tuber set
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
Atlas’ answer to urea, LAN, and other chemical nitrogen sources, Ghwamis-PLUS is an ammonium sulphate-based product that delivers a steadier nitrogen supply through the root zone while resisting leaching losses.
Its balanced nitrogen and micro-element profile supports strong vegetative growth, healthy canopy development, and better recovery after stress. It is a budget-friendly option for potato growers looking to bring a biological product into the programme, either to support early growth or to help maintain crop strength through the season.
- Farmers notice: stronger canopy growth and better stress recovery
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
Formulated as the flagship of Atlas Fertilizers, The Real McCoy leaves nothing out. Every nutrient is sulphate-based for superior uptake and balanced nutrition, supporting strong crop development, steady tuber bulking, and consistent yields through the season.
Designed for growers who invest in quality, not shortcuts, its low-chlorine blend helps protect sensitive crops while delivering the complete nutrition needed to push potato performance to a higher level.
- Farmers notice: potatoes that size up beautifully at harvest
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
3.1.5(22) is a biological version of a tried and tested NPK blend, offering a more budget-friendly alternative to The Real McCoy. Formulated on a potassium chloride base, it is rich in iron, calcium, and manganese, which play an important catalytic role in photosynthesis and overall crop function.
In potato programmes, it supports steady crop development and the potassium demand needed for tuber bulking and harvest quality.
- Farmers notice: improved bulking and even tuber size
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
- Soil health: supports active soil life for better structure and nutrient uptake
- Low burn risk: organically buffered, low-salt formulation safe for delicate growth stages
10.1.10(21) is a specialised fertilizer that delivers steady, reliable feeding through an organic substrate that helps reduce leaching. A small phosphate component supports new root development, while added sulphur and micro-elements contribute to efficient protein synthesis and steady crop function.
The sustained nutrient release helps maintain balanced vegetative growth and supports tuber development, keeping the crop healthy and productive through the season.
- Farmers notice: steady bulking and potatoes that size up evenly
- Dual action: feeds today’s crop while rebuilding soil for next season
- Slow-release formula: nutrients stay available longer, reducing waste and leaching
