Chitin is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. It is the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans (e.g., crabs, lobstersand shrimps) and insects, the radulas of mollusks, and the beaks of cephalopods, including squidand octopuses. In terms of structure, chitin may be compared to the polysaccharide cellulose and, in terms of function, to the protein keratin. Chitin has also proven useful for several medical and industrial purposes.
In its unmodified form, chitin is translucent, pliable, resilient, and quite tough. In arthropods, however, it is often modified, becoming embedded in sclerotin, a tanned proteinaceous matrix, which forms much of the exoskeleton. In its pure form, chitin is leathery, but in most invertebrates it occurs largely as a component of composite materials. Combined with say, calcium carbonate, as in the shells of Crustacea, it produces a much stronger composite, harder and stiffer than pure chitin, tougher and less brittle than the mineral substance alone. Another difference between pure and composite forms can be seen by comparing the flexible body wall between the segments of a caterpillar (mainly chitin) to the stiff, light elytron of a beetle (containing a large proportion of sclerotin).
Crab shells have elevated levels of chitin, which encourages soil microorganisms to exude enzymes known as chitinases, which break down the chitin that's a part of nematode egg shells.
The existence of chitin within the fertilizer helps it be an all natural biopesticide that's non-toxic to animals, birds, plants and fish.
These kinds of “good guys” are able to break down the chitin contained in the egg shells of nematodes. This results in many fewer nematodes.
Crab meal is an organic, eco-friendly fertilizer. It's made by drying shells in a kiln and then grinding them into the fine dust. The crabs are usually gathered from Mexico to Maine.
Most recent studies point out that chitin is a good inducer for defense mechanisms in plants It has alsobeen assessed as a fertilizer that can improve overall crop yields. The EPA regulates chitin for agricultural use within the USA. Chitosan is prepared from chitin by deacetylation.

Indonesian - Dyacopterus spadiceus – The Indonesian bat is a predominantly fruit eating bat which results in a more phosphorous driven guano offering the gardener a sweet end product. The fruits consumed are figs, guava, lychee, banana, dates and chickoo. The high phosphorous indicates that the guano was harvest from the bottom of the pile. And Also due to the amount of rainfall in the tropics the water drains guanos of their nitrates.
Jamaican - Artibeus jamaicensis – The Jamaican bat feeds predominantly on mangoes, avocado’s, and figs. The high phosphorous count is an indication that it comes from the bottom of the pile. Also because of the high rainfall rate the nitrates are drained out. Mexican –
Mexican Free Tailed Bat – This is a more nitrogen rich guano because the diet consists of ants, beetles, dragon flies, wasps, beetles, and ants. Plus the guano is harvest from the top of the pile. With the Mexican region being more dry in climate the nitrates do not get leached out.
Peruvian – seabird guano – They have a diverse range of foods because of their ability to feed on marine life as well as land insects. This is the reason why you see a high N and P. All guanos that have the sunleaves label on it are required by the company to undergo certain criteria to harvest and package the guano.
Masks are required when workers are handling the product.
