Chitin-Rich Organic Soil Amendment for Strong Roots and Healthy Soil Crab/Lobster Shell Chunks from The Soil Makers are a nutrient-rich organic soil amendment designed to improve soil structure, enhance microbial activity, and support healthy plant growth. Derived from natural crab shells, this amendment provides a balanced nutrient profile of 5-3-0 NPK, along with 17% calcium and 1% magnesium, helping strengthen plant cell walls and support vigorous root development. Crab shells are naturally high in chitin, a compound that stimulates beneficial chitin-eating bacteria in the soil. These beneficial microbes help enhance soil biology while contributing to a healthier and more resilient growing environment. In addition to providing nutrients, crab shell chunks improve soil structure by increasing organic matter and moisture retention while giving roots a natural structure to anchor and expand. This versatile amendment can be used in garden beds, lawns, containers, and raised beds, making it a valuable addition to both vegetable gardens and ornamental landscapes. Key Benefits: NPK 5-3-0 organic nutrient source Contains 17% calcium and 1% magnesium Improves soil structure and organic matter content Enhances moisture retention and root development Rich in chitin to stimulate beneficial soil microbes Supports healthy soil biology and nutrient cycling Suitable for lawns, gardens, containers, and raised beds Biological Benefits: High levels of chitin help encourage beneficial chitin-eating bacteria in the soil. These microbes support soil health and can help reduce pressure from pests and pathogens that rely on chitin-based structures. Crab shell amendments may help discourage pests such as: Ants Grubs Root nematodes Slugs and snails They can also help suppress weeds and discourage digging from animals around bulbs and root crops. How to Use: Soil PreparationWork crab shell chunks into the soil before planting to improve soil structure and nutrient availability. Top DressingApply around existing plants, garden beds, or lawns to gradually enrich the soil over time. LawnsBroadcast with a spreader and water in to help incorporate into the soil. Seasonal applications can help build long-term soil health and support stronger plant growth. Ideal For: Vegetable gardens Flower beds Perennial plantings Raised beds and containers Lawn care programs
