Citrus
Vegetables need consistent nutrition for quality and yield.
Atlas fertilizers supply the balanced organics and minerals that support vigorous roots, steady growth, and the premium colour and size markets reward.
Citrus trees need steady feeding for excellent fruit set and colour. Atlas fertilizers blend organics and minerals that keep roots active and support even growth across the orchard.

Fertilizer That Builds Soil While It Feeds Crops
Most conventional fertilizers give your crops a quick burst of nutrients, then wash away or lock up in the soil. Over time, this depletes soil life, forcing you to use more fertilizer just to maintain yields.
Atlas fortified organic fertilizers reverse this cycle. They feed your soil first – rebuilding organic carbon, activating microbes, and releasing nutrients steadily throughout the season. The result: healthier soil, stronger plants, and improving yields season after season.
Citrus productivity relies on sustained nutrition through flowering and fruit development. Atlas fertilizers supply the organics and minerals that support vigorous root systems, consistent fruit set, and the sizing and quality that command premium prices.

Fertilizers For Citrus Growers
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 your citrus steadily instead of flushing through with heavy rain or irrigation, helping reduce nitrogen losses and growth swings.
By keeping nitrogen in the root zone, N-Boost supports an active, well-leafed canopy, helping trees hold fruit size through both heat and wet spells.
- Farmers’ notice: strong canopy, more consistent yields
- 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.
Used for years on row crops and fruit trees, 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 strong, healthy growth throughout the season.
Formulated on a potassium chloride base, Nitro-K performs exceptionally well on citrus where balanced potassium drives fruit fill, colour development, and juice quality, while maintaining overall tree health.
- Farmers’ notice: improved fruit fill and enhanced shelf-life
- 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
- Apply 2 – 2.5kg N per ton of citrus harvested.
- For a 60mt yield, this equals 120 -150kg N, so apply 1200 – 1500kg Nitro-K in a single post-harvest application.
- Use in conjunction with Tropi-K or Super-K to achieve potassium 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, driving stronger flowering, improved fruit set, and even fruit development.
Designed for fruiting crops and proven on citrus, The Real McCoy supports healthy trees, vibrant colour, and consistent yields season after season
- Farmers’ notice: healthier trees and fuller fruit 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
- Apply as a post-harvest nitrogen and potassium fertilizer to achieve potassium targets for the season. Use in conjunction with Super-N as a nitrogen source.
High-K is a potassium-rich blend with a small amount of nitrogen, formulated for high-value fruit crops like citrus, bananas, macadamias and avocados. In citrus blocks, it fits wherever trees need extra potassium at key stages, especially from fruit set through sizing and colour development.
High-K uses KCl buffered in an organic base that also releases orthophosphate the tree can use straight away. This keeps more nutrients in the root zone and softens the salt effect, reducing the risk of fertilizer burn. The result is active roots and soil life that can support more uniform fruit size, better packout from orchard to market.
- Farmers’ notice: better colour, longer shelf-life
- 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.
Organi-ZINC is a fortified zinc solution formulated to correct deficiencies and boost nutrient uptake in citrus orchards. Its organic base buffers the zinc against acidic soil conditions, keeping it plant-available even in sandy or high-rainfall areas where leaching is common.
By complexing zinc with organic acids, Organi-ZINC supports strong flushes, and balanced canopy growth.
- Farmers’ notice: improved flowering and better fruit fill
- 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
- Use Organi-ZINC as a remedial or maintenance application to achieve adequate zinc levels in the sap and leaf.
Organi-BOR is a biological boron solution designed for both maintenance and soil correction applications in citrus orchards. Its organic base keeps boron available for longer, resisting leaching even in sandy or high-rainfall soils.
By enhancing the movement of sugars and nutrients within the tree, Organi-BOR supports stronger flowering, better fruit fill, and unbeatable orchard performance throughout the season.
- Farmers’ notice: improved fruit size, and shelf-life
- 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
- Use Organi-BOR as a remedial or maintenance application to achieve adequate boron levels in the sap and leaf.
