Down to Earth™ Shrimp Meal 6-6-0 All-Purpose Fertilizer — 15lb / OMRI Listed®

Shrimp Meal 6-6-0 — All-Purpose Organic Nutrition with Natural Calcium

Down To Earth Shrimp Meal 6-6-0 is an all-purpose organic fertilizer derived from finely ground Pacific shrimp processing by-products. With a balanced 6-6-0 NPK analysis plus natural calcium content from shrimp shells, it delivers nitrogen and phosphorus in an organically complexed form that breaks down steadily in the soil to support vigorous, sustained plant growth rather than the flush-and-crash cycle typical of synthetic nutrient applications.

The chitin-rich shrimp shell fraction provides an additional benefit beyond direct plant nutrition: chitin is a natural substrate for beneficial soil bacteria, including species known to help suppress certain soil-borne fungal pathogens over successive applications. Finely ground for rapid breakdown in the soil profile, this 15lb bag is OMRI Listed for use in certified organic production programs.

Key Features & Benefits

• Balanced 6-6-0 NPK plus calcium: Equal nitrogen and phosphorus with natural calcium from shrimp shells supports vegetative growth, root development, and cell integrity.
• Chitin-rich organic source: Shrimp shell chitin feeds beneficial soil bacteria and may contribute to suppression of certain soil-borne pathogens over successive applications.
• Rapid soil breakdown: Finely ground particle size accelerates organic matter decomposition and nutrient release compared to coarser-ground meal products.
• OMRI Listed: Approved for use in certified organic production programs, meeting input standards for organic vegetable, herb, and flower production.
• 15lb bag: Sized for season-long applications across garden beds and greenhouse benches.

Who Should Use This

Certified organic vegetable producers, home gardeners, greenhouse growers, and herb farmers who need a versatile all-purpose organic fertilizer with balanced N-P nutrition and natural calcium benefit are the direct fit for Shrimp Meal 6-6-0, particularly as a soil amendment worked in at bed preparation or applied as a top-dress mid-season.

Frequently Asked Questions

Does shrimp meal have an odor?

Like most marine-derived fertilizers, Shrimp Meal 6-6-0 has a mild fish-like odor. The smell dissipates as the product is incorporated into the soil and begins decomposing, and it is not an indicator of product quality.

Can shrimp meal be used in container growing?

Yes. Incorporate it into the potting mix at planting or apply as a top-dress during the growing season, using the lower end of recommended rates in containers to match the smaller root zone volume.

Does the chitin from shrimp shells really suppress pathogens?

Chitin amendments stimulate chitinase-producing bacteria that can suppress certain soil-borne fungal pathogens over time with repeated applications. This is a soil biology effect rather than a direct fungicide action, so benefits build over successive growing cycles.

How quickly does shrimp meal release nutrients?

Finely ground shrimp meal breaks down relatively quickly compared to coarser organic materials. Nitrogen and phosphorus become plant-available within a few weeks of application under warm, moist soil conditions that support microbial activity.
