SOIL APPLICATION · COMPREHENSIVE SOIL CONDITIONER
Natural granular soil conditioning for balanced mineral nutrition, root development and crop resilience.

Product Overview
MNG PRILL CaMgS is a natural granular soil conditioner designed to support soil health and crop productivity across a wide range of soil types and crops. The formulation combines calcium, magnesium, silicon and iron within a mineral-based soil-conditioning system. Its granular form is designed for professional soil application and supports balanced mineral nutrition, root-zone function and crop development. Suitable for all soil types and integration into crop-specific soil-fertility programmes.
Key Benefits
Balanced mineral nutrition supports root development and helps crops access nutrients more effectively.
Calcium contributes to plant structure and root-zone mineral nutrition.
Magnesium plays a central role in chlorophyll-related processes and crop metabolism.
Silicon forms part of the mineral matrix and contributes to plant structural support and resilience.
The granular soil-conditioning system is designed to support soil structure, moisture retention and root-zone performance.
Contributes to tissue structure, supports active root and crop development and is a major component of the mineral formulation.
Central component of chlorophyll; supports photosynthesis, enzyme activation and crop metabolism.
Contributes to the mineral soil matrix, supports plant structural integrity and complements calcium and magnesium nutrition.
Contributes to enzyme systems and chlorophyll-related metabolism; supports active crop development.
Designed to contribute to improved soil conditions, moisture retention and root-zone function.
Supports up to 30% reduction in additional mineral fertiliser input*, subject to crop demand, soil analysis, nutrient status and the complete fertiliser programme.

All soil types
80–180 kg/ha
SOIL APPLICATION ONLY. Compatible with standard agricultural application equipment.
Flexible application timing
Selection: Match rate and timing to crop, soil type and analysis, nutrient status, crop demand, irrigation strategy and fertiliser programme. The midpoint is a range reference, not a universal recommended rate. Select the final rate according to crop and soil conditions and the approved MNG programme. 1 ASSESS THE SOIL · Review soil type, pH, nutrients, moisture and salinity where relevant. 2 ASSESS THE CROP · Review crop demand and production target. 3 SELECT THE RATE · Use 80–180 kg/ha according to crop requirement. 4 CALIBRATE EQUIPMENT · Ensure accurate, uniform granule distribution. 5 APPLY TO SOIL · Use suitable agricultural soil-application equipment. 6 POSITION FOR ROOT ACCESS · Where appropriate, distribute or incorporate within the active root-zone layer. 7 INTEGRATE NUTRIENTS · Use PRILL CaMgS within a crop-specific fertility strategy. 8 MONITOR RESPONSE · Assess roots, crop vigour, soil condition, nutrient response, yield and quality to refine future programmes. Match application rate, timing and placement to soil type, crop demand, nutrient status and production objective. Integrate PRILL CaMgS into the complete MNG Soil · Water · Plant programme.
