Other Natural Fertilizers
There is a large range of natural fertilizers available on the market today.
Do not be misled by the N-P-K numbers that suggest manure is less powerful than chemicals. The values of manure and organic fertilizers in general, are often based on the relative amount of nitrogen (N), phosphoric acid (P) and potash (K) they contain. While these are important elements, it is misleading to make a direct comparison between farm manures and chemical fertilizers on the basis of the relative amounts of N-P-K.
Alpaca Manure (1.7-.69-1.2) - is lower in organic matter content than the manure from most other barnyard livestock (cows, horses, goats and sheep) creating a higher concentration of nutrients as well as improves soil texture and water-holding capacity. This lower organic content allows alpaca manure to be spread directly onto plants without burning them. It is the decomposition of organic matter content of the manure that indicates their efficient digestion system. The nitrogen and potassium content of alpaca dung is comparatively high, an indication of good fertilizer value.
Bird Manures - Bird manures tend to be "hotter", where the plants can be burned easily if overused. Overall they are much richer in many nutrients, especially nitrogen, which marijuana plants require in their veg phase in copious amounts. But not the flower phase, thus this type of fertilizer use is limited.
Chicken Manure (1.1-1.4-0.6) - is common among farmers. It's high in nitrogen, (great for vegging plants not flowering), but can easily burn plants unless composted first. A small amount of dried chicken manure can be mixed in small concentrations directly into soil. Chicken manure is also a common ingredient in some mushroom compost recipes. One potential concern for the budding organic farmer, is the large amount of antibiotics fed to domestic fowl in large production facilities. It is also suggested that some caution should be used when handling chicken droppings, whether fresh or dried.
