Slow Release N-P-K

Slow-release organic fertilizer from dungeness crab, a by product of shellfish processing, is air-dried at low heat and crushed for a uniform easy-to-apply amendment. Studies have found that chitin provides a source of carbon and nitrogen for microbial growth in soil. Beneficial chitin-feeding microbes multiply in the soil and consume the chitin in the shell meal until it is gone. At that stage they move on to consume any other high chitin sources that might be in the soil.

  • Apply at 500-2000 lbs per acre, or 5-10 lb/100 sq ft.
  • Apply 2-3 lbs as a top dress, 1-2 times per growing season
  • Makes an incredible compost bio-activator
