Poultry manure

The second component for synthetic (on straw basis) compost preparation is poultry manure. Broilers manure is used generally; contained on a bedding of sawdust, seed peelings and straw cut into small pieces.


Poultry manure on straw

The chickens excrement must be dry (humidity not higher than 40%), friable, with no clods or rubbish. This kind of manure will be easily applied, uniformly distributed and mixed with straw, and as a result, the substrate becomes more uniform and hence, more qualitative.

The optimal nitrogen content in poultry manure 3.5 5 %.
The minimal nitrogen content in chickens excrement suited for use is 2.5%.


Storage of poultry manure under a shed on a concrete platform

The chickens excrement is stored under a shed on asphalted or concrete floor.

Because of the loss of nitrogen, its undesirable to store fresh poultry manure for more than 1 month. Moreover, long-term stored poultry manure represents favorable conditions for the multiplication of yellow-green mold, especially when the manures humidity is high.

In literature, it is mentioned that theres a possibility of using layer hens manure of cellular content. Despite the fact that the composition of this manure is similar to the composition of broilers manure, no one works with it in practice. The reason for this is that the watery manure of layer hens is hard to uniformly apply to and mix with the straw to obtain a uniform mass of substrate. Greasy areas appear in the compost, they are a constant source of ammonia, which adversely affects the crop.

Layer hens manure can be dissolved in water and used along with recycled water, but this technology requires additional work.
