Potatoes

Originally formulated for leafy green vegetables, Veg-Mix quickly proved its value on potatoes across different soil types. Its balanced NPK profile and fortified organic base deliver steady nutrition that supports strong root systems, healthy canopy growth, and uniform tuber development.

Use once-off upfront for full-season feeding, or combine with The Real McCoy for improved size and consistent skin finish. On seed potatoes, pair with Organi-D for better root establishment and early vigor.

• Farmers’ notice: stronger plants, and potatoes that bulk evenly right through the row
• 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

• Incorporate 1000 – 2000kg/ha into the ridge before planting in order to meet phosphate demands. Apply The Real McCoy either at the same time or as a topdressing at re-ridging to achieve potassium and nitrogen targets.

Bean-Mix is a potassium-weighted NPK blend widely used on potatoes and other crops that respond to extra K. In potatoes, its balanced nitrogen, phosphorus and potassium support early root growth and a healthy canopy, which later shows up as better sizing and stronger yields.

When worked thoroughly into the ridge or bed at land preparation, Bean-Mix provides a solid nutrient base right through the season.

• Farmers’ notice: potatoes that handle grading with fewer bruises and rejects
• 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

• Bandplace to achieve Phosphate targets.

The Real McCoy is Atlas’ flagship fertilizer; a full-spectrum blend that leaves nothing out. Every nutrient is sulphate-based for superior uptake and balanced nutrition, supporting strong canopy growth, uniform tuber sizing, and improved skin finish. Designed for high-value crops and proven on potatoes, The Real McCoy delivers healthy plants and consistent yields season after season.

• Farmers’ notice: even bulking, and 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

• Incorporate The Real McCoy into the ridge before planting to achieve potassium targets for the season – this should be done in conjunction with Veg-Mix or Organi-D to meet phosphate demands. Alternatively use it as a side-dressing at re-ridging.

Tropi-K is a special blend of potassium with a touch of nitrogen. Its phosphate comes from the organic base as orthophosphate – a stable, non–water-soluble form that’s immediately available to plants.

Formulated for high-value crops, it performs exceptionally on potatoes where balanced potassium supports uniform tuber bulking, improved skin finish, and stronger plants. The sulphate-based potassium source lowers burn risk and enhances microbial activity for healthier, more resilient crops.

• Farmers’ notice: more consistent 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

• Broadcast Tropi-K as a soil correction or topdressing to achieve potassium targets.

High-K is a potassium-rich blend with a small amount of nitrogen, originally formulated for high-value fruit crops like bananas, macadamias and avocados. On potatoes, it fits wherever the crop needs extra potassium at key stages, typically from tuber set and early bulking through to the last passes before lifting.

High-K uses KCl buffered in an organic base that also releases orthophosphate the crop can use straight away. This keeps more nutrients in the ridge and softens the salt effect, reducing the risk of fertilizer burn. The result is active roots and soil life, with more plant energy ending up in well-sized potatoes.

• 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

• Broadcast to achieve potassium targets.

N-Boost is a leaching-resistant nitrogen source enriched with biologically active organic matter, magnesium, lime and a range of micro-elements. This balanced mix feeds potatoes steadily instead of flushing through with heavy rain or irrigation, helping reduce nitrogen losses and growth swings.

By keeping nitrogen in the ridge and root zone, N-Boost supports an active canopy and more stable growth, helping the crop carry its bulking and yield potential through both dry and wet spells.

• Farmers’ notice: deeper green tops, and even bulking through the ridge
• 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

• Bandplace or broadcast to achieve nitrogen targets.

Originally formulated for pasture and lawn, Super-TOP has proven highly effective on potatoes as a reliable topdressing alongside Atlas basal fertilizers. Its nitrogen-weighted blend, balanced with potassium and key micro-elements, keeps plants vigorous and resilient through the growing season.

Apply at key stages of canopy and tuber development to maintain healthy tops and consistent bulking.

• Farmers’ notice: stronger growth, and potatoes that bulk evenly right through the ridge
• 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

• Broadcast as a nitrogen and potassium topdressing at week 5 after emergence before re-ridging.

Used for years on row crops and potatoes, Nitro-K provides a sustained release of nutrients that keeps soil and leaf nutrition in balance. By preventing calcium from being locked up by excess potassium, it supports vigorous plant growth and steady tuber bulking throughout the season.

Formulated on a potassium chloride base, Nitro-K performs well across most soil types and helps produce potatoes with consistent size, smooth skins, and significantly improved shelf-life.

• Farmers’ notice: steady bulking, and potatoes that size up evenly right through 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

• Used as an early nitrogen and potassium boost for increased initiation and vigour, Nitro-K is an excellent topdressing before re-ridging.
