Rock Phosphate is a natural mineral fertilizer made from 90% rock phosphate with naturally occurring calcium and trace minerals. As a long-lasting, slow-release source of phosphorus, it is typically applied during soil preparation and planting to build a foundational nutrient reserve that supports root development over an extended period.

It is often used together with PROM (Phosphorus Rich Organic Manure) at planting time for Brinjal and other long-season fruiting vegetables.

Key Benefits:

  • Supports strong root development through a sustained phosphorus supply
  • Encourages healthy flowering and fruiting over the growing season
  • Improves phosphorus availability in soil with deficient natural levels
  • Enhances overall soil fertility with added calcium and trace minerals
  • Promotes vigorous plant growth from the early root-establishment stage

Gardener Tip: Work Rock Phosphate into the soil at least a few weeks before planting whenever possible, rather than applying it right before sowing. Because it's a slow-release mineral, giving it a head start lets soil microbes begin converting it into a plant-available form before roots actually need it.

How to Use:

  1. Sprinkle the recommended quantity around the plant base.
  2. Mix lightly with the topsoil to integrate it into the root zone.
  3. Water thoroughly after application.
  4. Best applied during planting or early growth stages, then every 45-60 days as needed.

Dosage: Small Pots: 15-20 g, Medium Pots: 25-40 g, Large Pots: 50-75 g, or as required.

This product is suited to the following plants. Where Anandi Greens sells the matching seed directly, the plant name links to that product:

  • Nutrient Composition: Available Phosphorus (P₂O₅) 18-22%, Calcium 25-30%, Trace Minerals 48-57%
  • NPK Ratio: Natural source of Phosphorus (P) with Calcium and trace minerals
  • Coverage Area: Covers approximately 30-60 medium-sized pots or 40-70 sq. ft. garden area, depending on application rate.
  • Application Frequency: Every 45-60 days, or during soil preparation and planting
  • Application Area: Home Gardens, Terrace Gardens, Kitchen Gardens, Balcony Gardens, Nurseries, Flower Beds, Raised Beds, Pots & Grow Bags, Organic Farming
  • Growth Stage: Ideal for Seedling, Vegetative, Root Development, Flowering, Fruiting, and Mature Plant stages
  • Shelf Life: Best used within 24 months from the date of manufacture when stored properly
  • Country of Origin: India
  • Safety Information: Keep out of reach of children and pets. Avoid inhaling dust and wash hands after handling. Not for human consumption.
What is Rock Phosphate fertilizer used for?

It is used as a natural, slow-release source of phosphorus to support root development, flowering, and fruiting.

How much phosphorus does Rock Phosphate contain?

It contains approximately 18-22% available Phosphorus (P₂O₅), along with 25-30% Calcium.

How often should Rock Phosphate be applied?

Apply every 45-60 days, or primarily during soil preparation and planting.

Is Rock Phosphate the same as PROM?

Rock Phosphate is a pure mineral source, while PROM combines rock phosphate with organic matter and beneficial microbes for improved availability.

Can Rock Phosphate be used for fruit trees?

Yes, it supports fruit trees like Lemon, Guava, and Mango alongside vegetables and flowering plants

How much Rock Phosphate should I use per pot?

Use 15-20 g for small pots, 25-40 g for medium pots, and 50-75 g for large pots.

Is Rock Phosphate a fast-acting or slow-release fertilizer?

It is slow-release, making it ideal for establishing a long-term phosphorus reserve in the soil.

Can Rock Phosphate be combined with nitrogen fertilizers?

Yes, it pairs well with nitrogen-rich options like Mustard Cake or Neem Cake for a balanced feeding plan.

Is Rock Phosphate suitable for organic farming?

Yes, it is a naturally occurring mineral fertilizer widely used in organic farming practices.

How should Rock Phosphate be stored?

Store in a cool, dry place; it remains effective for up to 24 months

Can I apply Rock Phosphate to seedlings?

It's generally better to incorporate Rock Phosphate into the soil before sowing or transplanting, since its slow-release nature means it works best as a foundational soil amendment rather than a direct seedling treatment.

Can I use Rock Phosphate in grow bags?

Yes, mixing it into the soil during grow bag preparation is a common and effective use case.

Can Rock Phosphate burn plants?

Burning is unlikely since Rock Phosphate is a slow-release mineral, but using significantly more than the recommended dose can disrupt overall soil nutrient balance over time.

How long does Rock Phosphate take to become available to plants?

Being a slow-release source, Rock Phosphate can take several weeks to a few months to fully become available, depending on soil conditions like pH and microbial activity.

Can Rock Phosphate be mixed with compost or vermicompost?

Yes, mixing Rock Phosphate with compost or vermicompost helps create a more active soil environment that improves phosphorus availability over time.

Is Rock Phosphate suitable for acidic or alkaline soils?

Rock Phosphate tends to become more available in slightly acidic soils; in very alkaline soils, phosphorus availability may be reduced, so testing soil pH can help determine effectiveness.

Can Rock Phosphate be used for fruit trees?

Yes, it is commonly used for fruit trees like Lemon, Guava, and Mango as a long-term phosphorus reserve.

Is Rock Phosphate the same as superphosphate?

No, superphosphate is a chemically processed, fast-release phosphorus fertilizer, while Rock Phosphate is a naturally occurring, slow-release mineral source.

How often should Rock Phosphate be reapplied?

Every 45-60 days, or primarily at the time of soil preparation and planting, since its slow-release nature means it doesn't need frequent reapplication.

Can Rock Phosphate replace a complete fertilizer programme?

No, since it only supplies phosphorus and calcium, it works best alongside nitrogen and potassium sources for complete plant nutrition.
