Calcium Carbonate 50 lb. — Mississippi Lime CalCarb R2

Pure calcitic limestone powder (CaCO₃) from Mississippi Lime — one of the most trusted names in agricultural lime. At 200 mesh fineness, CalCarb R2 reacts quickly in the soil to raise pH, improve calcium availability, and create the optimal growing environment for nutrient uptake. A foundational amendment for any serious soil management program.

Why Growers Use CalCarb R2

  • Fast-acting pH correction — 200 mesh particle size means rapid soil reaction compared to coarser limestone products
  • High calcium content — pure calcitic source delivers calcium directly to the root zone, supporting cell wall strength and nutrient transport
  • Neutralizes soil acidity — the most cost-effective acid neutralizer available; raises pH to unlock tied-up phosphorus, magnesium, and micronutrients
  • Improves soil structure — calcium flocculates clay particles, improving drainage, aeration, and root penetration
  • Broad crop compatibility — suitable for vegetables, field crops, turf, ornamentals, and hydroponic media pH adjustment
