Core product portfolio and specialty nutrient technologies

Mosaic manufactures balanced nutritional granules designed to deliver multiple nutrients within every individual particle.

  • MicroEssentials: Patented technology combining nitrogen, phosphorus, sulfur, and micronutrients like zinc in one uniform granule.
  • K-Mag (0-0-21.5 with 10.5% Mg and 21% S): Natural langbeinite mineral providing potassium, magnesium, and sulfur in a water-soluble form.
  • Diammonium Phosphate (DAP 18-46-0): Concentrated source of plant-available phosphate and starter nitrogen for basal crop placement.
  • Muriate of Potash (MOP 0-0-60): High-analysis potassium chloride supporting drought resilience and carbohydrate translocation.

Agronomic benefits of fused granule fertilization

Traditional physical blends can segregate during transport and spreading, leading to uneven nutrient distribution across fields.

  • Uniform nutrient distribution: Every plant receives an identical balance of macro and secondary nutrients.
  • Dual-form sulfur technology: Delivers sulfate sulfur for immediate uptake and elemental sulfur for season-long root feeding.
  • Enhanced zinc bioavailability: Acid-forming micro-zones around each granule keep zinc soluble even in high-pH alkaline soils.
  • Stronger early root proliferation and tillering in cereals, pulses, and oilseeds.

Application guidelines and soil health alignment

Apply Mosaic basal fertilisers at sowing or transplanting, placing granules below and beside the seed line. Base application rates on localized soil health card recommendations to optimize return on investment and preserve long-term soil mineral balance in accordance with the Fertilizer (Control) Order.

Common questions

What is Mosaic MicroEssentials fertiliser?

MicroEssentials is a proprietary granule that fuses nitrogen, phosphorus, sulfur, and zinc into every individual fertilizer particle.

What nutrients does K-Mag supply to crops?

K-Mag supplies water-soluble potassium (21.5% K2O), magnesium (10.5% Mg), and sulfur (21% S) in a low-chloride form.

How does dual-form sulfur in MicroEssentials help plants?

Sulfate sulfur provides immediate nourishment to young seedlings, while elemental sulfur breaks down slowly for sustained feeding throughout the season.
