compare them against another guano provider. Guanos are regionally specific. Peruvian will differ from jamacian due to the diet of the particular bats in those regions.
Example:
Sunleaves
Jamaican Bat Guano
Nothing is better for blooming flowers or ripening fruits than pure, high-phosphorus Sunleaves Jamaican Bat Guano (1-10-0.2). Now listed by the Organic Materials Review Institute (OMRI), Jamaican Bat Guano is most effectively used at the root zone to heighten root and flower development.
Gardeners can amend their soil with it, use it as a top dressing or create a "guano tea" and apply it directly to plant roots in a fortified water dilution. Eco-friendly harvesting from centuries-old cave deposits. Available in 2.2 pound bags or an 11 pound box.
Sunleaves
Peruvian Seabird Guano
With absolutely no chemical additives, Sunleaves Peruvian Seabird Guano (10-10-2) offers the highest quality in organic fertilization and is even listed by the Organic Materials Review Institute (OMRI).
Peruvian Seabird Guano is pelletized for water solubility with less mess. There is nothing like it for accelerating growth - growers can use Peruvian Seabird Guano indoors and out on houseplants, vegetables, ornamentals and fruit trees. Available in 2.2 pound bags or an 11 pound box.
Sunleaves
Mexican Bat Guano
High nitrogen Sunleaves Mexican Bat Guano (10-2-1) brings important nutrients to plants and adds active micro-organisms to soil. These tiny organisms unlock nutrients bound up in the soil and break down the compounds in the guano, releasing major soluble and trace nutrients to eager plant roots.
The result is increased soil porosity and a healthier root system. Mexican Bat Guano is now listed with the Organic Materials Review Institute (OMRI). Available in 1 pound bags or a 5 pound box.
Sunleaves
Indonesian Bat Guano
Perfect for encouraging multiple blooms and hardy root growth, phosphorus-rich Sunleaves Indonesian Bat Guano (0.5-12-0.2) is all natural and suitable for use indoors and out. Indonesian Bat Guano restores a natural balance in the garden without increasing soil salt content or acidity and is safe for use around people and pets. Available in a 2.2 pound bag and an 11 pound box.

GUANO
The 100% Natural Organic Soil Amendment
The word guano originated from the Quichua language of the Inca civilization and means "the droppings of sea birds". It is a misnomer to refer to bat dung as guano. As the word is used today, guano describes both bat and sea bird manure. The most famous guano was that used by the Inca. The guano would collect on the rainless islands and coast of Peru. Atmospheric conditions insured a minimal loss of nutrients. There is very little leaching of valuable material, nor is there a considerable loss of nitrogenous matter. For this the Inca would guard and regulate the treasured soil enricher. Access to the guano deposits were restricted to chosen caretakers. Disrupting the rookeries could result in punishment by death.
Guano became a very important part of the development of agriculture in these United States. During the peak of the guano era, drastic steps were taken to maintain a supply for the U.S. farmer. "On August 18, 1856, Congress passed an act to authorize protection to be given to citizens of the United States who may discover guano, under which any citizen of the United States was authorized to take possession of and occupy any unclaimed island, rock or key containing guano. The discoverers of such islands were entitled to exclusive rights to the deposits thereon, but the guano could only be removed for the use of the citizens of the United States."Nutrients in guano are as different as there are a variety of producers, food sources and environmental constraints. Sea birds eat strictly small fish and are not scavengers. Bat guano is available from one species that thrives on fruit, while another feasts on insects. Guano can be fresh, semi-fossilized or fossilized and will be a factor, among others, on the nutrient content when used.
Guano is provided in the ready to use condition, thoroughly aged to the vintage state of a good natural fertilizer. Guano can be used inside or outdoors for all living plants. Guano supplies fast and slow release nutrients to the biological system. Apply the pure guano in smaller amounts than ordinary barnyard or poultry manure. Applied as a top dressing and worked into the soil or mixed with water and applied, guano will have a dramatic influence. Hydroponic growers, in contrast to normal fertilization, are finding that guano and water are a natural alternative to chemical solutions. Use nitrogen guano for growth, phosphorus guano for budding and all guano for your plants general health and well being. Guano can be blended with topsoil before laying sod or grass seed and while planting trees and shrubs. Add guano to your container growing mix for a supercharged potting soil.
Holy Shit Batman! Is it really that much better than other composts such as bloodmeal, steer manure, etc?
I have an area on my land where the previous owners dumped their horse manure, it's been many years since the last dump but the earth is so fertile that everything that grows there is 4 times the size of everything growing in other locations.
