Hi everyone, I've read chicken manure pellets are a great slow release fertilizer that doesn't burn roots and improves the soil. Is it ok to use chicken manure pellets to fertilize container citrus? If so, is there a limit to how much I can use? Any drawbacks to using it for container citrus? Thanks for your help.

Manure is both a soil conditioner and a fertilizer. Because of its high content of soluble salts, it can also cause a lot of plant burning. Manure should never be applied fresh. Always compost it for one year or more. Manures vary greatly in nutrient content. The age and the type of manure create many variables. This makes it almost impossible to know how strong it is. As a rule the older the manure, the less nutrient value. Poultry manure is about twice as rich/strong as that of horse, cows and pigs. Manure is not very suitable for pots, or containers, as it is too easy to cause burning. Generally, manure is normally used in soil beds. It would be much safer to use your chicken manure in the form of a manure tea. Manure tea is made by simply infusing water with a source of manure. Prepare an old bucket to hold the manure. Take a nail and hammer, and poke hundreds of holes in the bottom and sides of the bucket. Set the "holy" bucket full of manure into another bucket of water for a few hours. Remove the manure bucket and your tea is ready. It is primarily a source of nitrogen and can be absorbed through the leaf as well as the root. As you might have guessed, it doesn't smell great. If it is flavor you want, try Lipton tea. - Millet (1,033-)

In addition to Millet's answer, I would research the pellet product that is available. It may be composted/ ammended, and may have an analysis of nutrient content on the package. Apart from that, the nutrient balance of grain fed poultry manure products, may be too high in Phosphorus, compared to Nitrogen, and hence the other elements as well, as a stand alone fertilizer.
This will probably determine the rate you could apply it, without over supplying the Phos.
Composted poultry manure has been seen to suppress Phytophora root rots.

Thank you Millet and pagnr for your inputs.
