DESCRIPTION

Enhance soil fertility and promote strong root development with Calphos Soft Rock Phosphate (5 lb), a natural source of phosphorus and calcium. This slow-release mineral fertilizer provides essential nutrients that support plant growth, improve flowering, and encourage fruit and vegetable production. Ideal for organic gardening, it gradually breaks down in the soil, supplying a long-lasting source of phosphorus without the risk of leaching.

Phosphorus is a key nutrient for root establishment, energy transfer, and bloom development, making Calphos an excellent choice for root vegetables, fruiting plants, and flowering ornamentals. In addition to phosphorus, this soft rock phosphate contains calcium, which strengthens plant cell walls and contributes to overall plant resilience. Together, these nutrients support vigorous plant growth and improved yields.

Easy to apply, Calphos Soft Rock Phosphate can be mixed into the soil before planting or used as a top dressing to provide continuous nourishment throughout the growing season. It is suitable for vegetable gardens, orchards, flower beds, and general soil improvement. The finely ground powder ensures efficient nutrient absorption, helping plants thrive in a variety of growing conditions.

Key Benefits:

  • Rich Nutrient Content: Averages 20% P2O5 (3% immediately available), 18% calcium.
  • Slow-Release Formula: Provides phosphorus and calcium for up to 5 years after application.
  • Supports Root Growth: Strengthens root systems and improves plant resilience.
  • Improves Soil Microbial Activity: Enhances beneficial bacteria for better soil health.
  • Reduces Nutrient Loss: Stays in the soil, minimizing runoff and maximizing plant uptake.
  • Versatile Application: Ideal for vegetables, trees, perennials, and general soil enrichment.

Application Guidelines:

  • General Use: Apply 5 lbs per 100 square feet or 1 ton per acre on phosphorus-deficient soils.
  • Trees & Perennials: Use 1-10 lbs per planting hole, depending on plant size.
  • Pre-Planting: Mix into the soil for best nutrient absorption.
  • Top-Dressing: Apply around plants as a slow-release nutrient source.

For larger applications, Calphos Soft Rock Phosphate is also available in a 50 lb bag.
