It is readily available (bagged, at nursery suppliers), and its formulation generally consists of a combination of wheat straw, dried blood, horse manure and ground chalk, composted together. It is an excellent source of humus , although much of its nitrogen content will have been used up by the composting and growing mushrooms.

For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, because horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3]

If organic manure is not available, they are permitted to use non-organic manure as long as the animals have room to roam, are not kept in the dark, and growers abstain from using genetically modified feeds. [12] Fresh manure, right from the stall, can cause issues because it can be too high in ammonia, or contain bacteria from the animal’s gut.
Spent soil or compost, and organic amendments such as biochar may be added, as may non-fermented material, in which case the boundary between bokashi and composting becomes blurred. A proposed alternative [ 20 ] is to homogenise (and potentially dilute) the preserve into a slurry, which is spread on the soil surface.
In the past, it was common for farmers to use animal manure to improve their soil fertility. In the 1920s, the farming community began also to use sewage sludge from local wastewater treatment plants. Scientific research over many years has confirmed that these biosolids contain similar nutrients to those in animal manures.
