The shells of crustaceans have two benefits for biological gardeners. They are largely made of calcium carbonate: There is a bit of phosphorus, nitrogen and magnesium in there- but it is the calcium carbonate they contain that is of value to us!

This calcium comes without the extra sulphur, as in gypsum, or the extra magnesium, as in dolomite. This is an important factor for the not till gardener, who wants a continuous calcium supply without the burden of excessive amounts of the other nutrients!

This crab meal is ground to the finest particle size available, as this increases the surface area of the material greatly, and equally speeds up the decomposition of the material in the soil.
