Spent mushroom compost Medium fertility. Tends to be alkaline, so not suitable for acid-loving plants. Source from organic mushroom-growers.

The effect of amending soil with other types of organic-rich material has also been investigated by sequential extraction. These materials include chicken manure and cowpea leaves (Li et al, 1997) spent mushroom compost, commercial humic acid and poultry litter (Shuman, 1998) and cow manure, pig manure and peat soil (Narwal and Singh, 1998). The mechanisms by which inorganic additives (zeolite, apatite and iron oxide) reduce uptake of Cd and Pb by crops have also been studied (Chlopecka and Adriano, 1997). 

Permitted If the material is known to be free from chemical and antibiotic residues when applied to the land battery manure, municipal compost (recognised), farmyard manure (bought in), slaughterhouse waste, mushroom compost, tannery waste, recognised proprietary organic manures e.g. Grancreta and Regenor...

A biologist will want to know something about the relationship of Bt to other bacteria, the natural function, if any, of the toxins, as well as the natural occurrence of the Bt strains. Numerous strains have been isolated from a wide range of habitats such as soil, mushroom compost, and stored products. Bt may be present in samples from beach deserts and tundra, and may multiply in cadavers of insects and other animals. Insecticidal activity does not correlate with the origin of the isolate, and many of them do not seem to be toxic for insects. Bt may be regarded as a ubiquitous soil microbe and common on vegetation. Their spores may be viable for years in the soil... 

The substrate in Cell A is mushroom compost the substrate in Cells B and C is a mixture of equal parts of peal/ aged steer manure/ and aged wood chips. The top is the first six inches, the bottom is at three feet, the front is near the inlet, and the back is near the outlet.

Many species thermophilic thriving in the 115-135°F. temperature range and commonly found in decomposing straw, horse and cow manures. Actinomyces are important soil constituents. They thrive in aerobic, well prepared mushroom composts. 

History, Use, and/or Medical Implications Streptomyces represents 80% of all actinomycetes which inhabit mushroom compost and is selected for its beneficial properties during Phase II. (See Chapter V). 

Habitat Frequency of Occurence Saprophytic, a common mold in soils, and endemic to composts prepared in direct contact with the ground. Although Chlysosporium species naturally inhabit the dung of most pastured animals and of chickens, today they are rarely seen in finished mushroom composts with the development of modern composting methods. 

Medium Through Which Contamination Is Spread Air soil and dung. Measures of Control Concrete surface used for composting isolation of mushroom compost from areas where untreated soils and raw dung are being stored and filtration of air during Phase II If Chlysosporium occurs before or at the time of casing, salt or a similar alkaline buffer can be applied to limit the spread of infection. 

Generally a saprophyte although some forms act as parasites. Ceotrichum species are extremely common in nature but infrequently encountered in mushroom compost—unless it has been prepared directly on soil. Ceotrichum dwells in soils, cow dung, old straw, compost piles and rots some fmits and vegetables. In general, species of this genus are mesophilic thermophiles and are therefore sensitive to pasteurization temperatures. 

The second site of contamination is horse manure/straw compost where it most frequently appears during spawn run. Oniy detrimentai when iarge outbreaks occur, Sepedonium spresence on compost can be traced to insufficient pasteurization or spent compost residues in the trays or sheives. Aithough not regarded as a serious competitor on mushroom compost, Sepedonium is another fungus beiieved to be a food source for mites (Kneebone, 1961). 

Saprophytic, common. Many thermophilic species participate in the decomposition of straw and manure in the making oL mushroom composts. Although Torula is rarely seen in agar culture, its cousin Rhodotorula, a red yeast, is frequently seen. 

Phase II The pasteurization and final conditioning of a mushroom compost, phenotype The observable physical characteristics resulting from interaction between the host environment and the genotype, photosensitive Sensitive to light, phototropic Growing towards light, pileus The mushroom cap. pith The central cottony stuffing in the stems of some mushrooms. 

In the environment, bacteria that have the ability to degrade PAHs have been reported. Saprotrophic soil fungi Pusarium solani, and yeast Rhodotorula glutinis metabolize pyrene as a sole source of carbon. Mushroom compost is reported to be used directly to ameliorate phenathrene contaminated soil. After 111 days incubation time, 36.7+2.9% loss of soil-associated phenanthrene was observed.
