Our Seashell Flour is derived from soft seashells that are washed, low temp dried and ground to a fine consistency, about the grade of coarse Raw sugar.
Seashells are much softer than Oyster shells, and as such provide a faster hitting Calcium source than our Oyster Lime. While it can be used as the sole buffering agent in soil, its lifespan would necessitate multiple top-ups throughout the crop cycle. We recommend using it alongside our Oyster Lime Powder grade for fast-growing, annual plants.
Application rates can range from 1/2 to 2 Tablespoons (7 grams to 42 grams) per 5L of soil. With reup applications fortnightly throughout the season.
