Nanophos is a natural sedimentary soft rock phosphate mined on the west coast of South Africa.

Soft rock phosphate is a natural, non-detrital sedimentary rock rich in phosphate minerals, used as a slow-release fertilizer to improve soil phosphate levels and promote long-term plant productivity.

As farmers increasingly seek more regenerative and sustainable agricultural products to enhance soil health, stimulate soil microbial activity and ensure plant nutrition, Nanophos provides a unique composition of Phosphorus, Calcium and Silicon.

Unlike synthetic fertilizers, which can cause water pollution and soil degradation, soft rock phosphate is a natural product that supports sustainable farming practices. Its slow-release properties minimize the risk of nutrient leaching into water bodies, helping to protect South Africa's precious natural resources.

DIRECT APPLICATION PHOSPHATE ROCK (DAPR)

KROPZ produces a phosphate rock product containing 22% P2O5. This product has a high reactivity (based on the citric soluble P), is partially water soluble and super fine with high reaction surface.

NANOPHOS IS UNIQUE IN THAT IT IS:

a natural mined product un-altered
a very fine product (requires no grinding) with a particle size of 60% less than 25 μm
a highly reactive sedimentary phosphate rock with a P2O5 citric solubility of > 35%.

partially water soluble with a P2O5 water solubility of > 10%
contains key elements, phosphorus (P), Silicon (Si) and calcium (Ca) required to sustain plant growth.
can be blended with most fertilizers and organic material.

BOOST SOIL FERTILITY NATURALLY WITH DIRECT APPLICATION PHOSPHATE ROCK

What is Direct Application Phosphate Rock (DAPR)?

Direct Application Phosphate Rock (DAPR) is a natural, slow-release phosphorus fertilizer derived from finely ground phosphate rock. It provides essential phosphorus to plants, enhancing root development, improving crop yields, and promoting sustainable soil health.

KEY BENEFITS:

Slow-Release Phosphorus – Ensures a steady supply of nutrients over time.
Enhances Soil Fertility – Improves long-term soil productivity and structure.
Eco-Friendly & Sustainable – Reduces environmental impact compared to synthetic fertilizers.
Boosts Root & Crop Growth – Supports plant development and yield.
Cost-Effective – Long-lasting effects reduce the need for frequent applications.

NANOPHOS ENSURES:

Having the benefit of natural fertiliser that work with the soil microbes to enhance the availability of plant nutrition and supporting the soil structure and water retaining ability.

Having access to natural plant available phosphate nutrition that adds to the benefit of soil and plant health without the pressure of adding excessive salts or changing soil pH and soil structure.

High reactivity which makes it more bioavailable to plants because of a very fine particle structure. The fineness of Nanophos ensures a larger surface area, which allows it to react more effectively with soil acids and release phosphate more readily.

NATURAL ORGANIC NANOPHOS SOFT ROCK PHOSPHATE

Nanophos contains 90 – 100 g P / kg Nanophos in its organic form and is registered under the Act 36 of 1947 as a Sedimentary phosphate rock powder and classified within the Group 2 Fertiliser category. Nanophos organic adheres to stringent standards monitored by The Department of Agriculture, Land Reform and Rural Development (DALRRD).

Technical Data Sheet

PHOSPHATE

The total phosphate content amounts to 9 – 10% soluble P.

35% of the P in Nanophos are immediately available as citrate soluble P (2% citric acid solution) while the remainder becomes available after a further three extraction cycles.

PHOSPHATE

Phosphate is an essential nutrient for all living organisms. It plays a vital role in photosynthesis, respiration, energy storage and transfer, cell division and cell enlargement. Phosphorus supports root growth and assists plants during cold winter conditions and increase the rate of water absorption.

NANOPHOS has all the characteristics as a P bearing mineral and fertilizer to provide or supplement the P nutrition plants require when used in the correct application. It is a slow-release source of P, ensuring efficient use of P, available over more than one planting cycle. It reduces P run-off and P fixation in soils.

CALCIUM

NANOPHOS contains 22% calcium (Ca). Calcium is essential for microorganisms to turn crop residues into organic matter, release nutrients and improve soil aggregation and water holding capacity. Calcium also plays an important role in neutralizing soil toxicity.

SILICA

Nanophos contains 26% silica (SiO2). Silica not only plays an important role in soil structure and stability but also increase P availability in soils by reducing soil sorption of P. Silica is beneficial for crops as it strengthens plant cell walls making it harder for pathogens to penetrate. Additionally, silica can stimulate a plants natural defence mechanisms making it more disease resistant.

MICRONUTRIENTS

NANOPHOS also contains levels of trace elements (micronutrients) that are required for plant growth, and overall plant health.
