Why is Guano so Good?

  • Bat Guano has a high percentage of natural living microbic flora. There is a predominance of beneficial fungus, actinomycetes and bacteria in it.
  • Bat Guano is a nematocide. It destroys the primary stage of the nematodes and thus eliminates them. Eliminating nematodes is equal to protecting the plant's radicular system, which improve nutrition and production.
  • Bat Guano is a fungicide and competes with disease causing microbes.
  • Bat Guano contain a high percentage (40% and more) of organic matter.
  • High content of cationic exchange, increasing the plant's feeding possibility.
  • Guano has a wide range of chelates (natural organic-mineral compounds with a high molecular weight), which give bat guano great structural stability and produces a high residual effect in the soil and substrate where it is applied.
  • Bat guano's composition varies according to the animals' feeding habits and the type and form of caves where they live, among other factors.
  • Following is a characterization (humid base) of BAT GUANO:
  • Nitrogen (N2) 2 - 6 + %
  • Phosphorus (P2O5) 1.5 - 10 + %
  • Potassium (K2O) 1.0 - 3,0 + %
  • Magnesium (MgO) 1.5 - 8 + %
  • Calcium (CaO) 3.5 - 9 + %
  • Iron (Fe2O3) 0.5 - 1.3 + %
  • Manganese (MnO) 0.4 - 0.8 + %
  • Copper (CuO) 0.2 - 0.5 + %
  • Zinc (ZnO) 0.2 - 0.4 + %
  • pH (water) 4.0 - 5.6
  • Organic Matter 40 - 60 %
  • C/N Relation 5/1 - 8/1
  • Fulvic Acids 15 - 20 %
  • Microbiological Flora 30 - 45
  • X 10E7 + U.F.C.
  • Humidity 30 % +/- 5 %

Need advice on which one to pick?

  • 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.
  • Some people use the word "Bat Guana" instead of "Bat Guano" when referring to this fertilizer.
  • Our Guano is provided in a 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 (see picture at top of page) 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.
