Archipelago Bat Guano 0-7-0 (55 lb)

Archipelago Bat Guano 0-7-0 in the original 55 lb package is the primary family option for larger gardens, orchards, farms, and repeated applications. This animal-based powdered fertilizer supplies phosphorus without added nitrogen, making it useful where a current soil test identifies a need.

Guaranteed analysis and role

The product provides 7% available phosphate, approximately 15% calcium, and 0.5% manganese. Phosphorus supports energy transfer, root establishment, flowering, and fruit development when soil levels are deficient. Because phosphorus remains relatively immobile in most soils, incorporate the powder where developing roots can access it instead of leaving it concentrated on the surface.

The bulk format is useful for planned applications across several beds or successive plantings. It reduces handling compared with purchasing multiple small bags while still requiring careful measurement. Store the closed bag in a dry location and avoid creating airborne dust.

Recommended applications

• Preparing vegetable and flower beds before planting
• Supporting flowering or fruiting crops in phosphorus-deficient soil
• Amending orchard and perennial planting areas
• Making measured applications across multiple beds

Published general-use guidance is 1–2 lb per 100 sq ft. Refine that rate using a soil test, crop needs, and regional recommendations. This is not a balanced fertilizer and is not intended to supply every major plant nutrient. Excess phosphorus can create nutrient imbalances and increase environmental risk, so avoid routine or speculative use in soil that already contains sufficient phosphorus. Wear appropriate protection while handling the fine powder and wash after use.
