MaGypSil

Gypsum–Magnesium–Silicate
Soil Amendment

MaGypSil is a blended mineral soil amendment combining hydrated magnesium silicate with naturally mined agricultural gypsum. It is designed to improve soil structure, cation exchange, and long-term soil chemical stability while supplying calcium, magnesium, sulfur, and plant-beneficial silicon.

Guaranteed Mineral Profile
• Silicon Dioxide (SiO₂): 22.0%
• Magnesium Oxide (MgO): 17.0%
• Calcium Oxide (CaO): 15.0%

Core Agronomic Benefits

  1. Improves Soil Structure and Aggregation
    The combination of calcium and magnesium supports aggregation and flocculation, helping loosen tight soils, reduce crusting, and improve pore structure.

  2. Enhances Cation Exchange Capacity and Buffering
    MaGypSil improves the soil’s ability to hold and exchange nutrients, supporting more stable fertility and reducing nutrient losses.

  3. Supports Sulfur Availability Through Natural Processes
    Gypsum contributes sulfur that becomes available through microbial activity, supporting protein synthesis and overall plant metabolism.

  4. Moderates Soil Acidity Over Time
    Through gradual mineral weathering, MaGypSil helps moderate soil acidity without rapid pH swings, supporting long-term soil chemical balance.

  5. Provides Gradual Release of Plant-Beneficial Silicon
    Silicon supports stronger plant tissues and improved resilience, particularly under stress from heat, disease pressure, or lodging risk.

  6. Improves Water Movement and Rhizosphere Dynamics
    Better aggregation and pore continuity improve infiltration, drainage, and root-zone oxygen balance.

Where MaGypSil Fits Best


• Compacted or structurally degraded soils
• Fields requiring calcium and sulfur support
• High-CEC management systems
• Crops sensitive to poor drainage or crusting
• Programs seeking combined gypsum + silicate benefits

Typical Application
100–300 kg per hectare (approximately 90–270 lb per acre), incorporated into the top 4–6 inches of soil. Rates should be guided by soil test results and crop requirements.
