The official line on adding coal or smokeless fuel ash to the garden and particularly the vegetable plot, is don't do it. Apparently the ash can contain trace elements of arsenic and metals such as cadmium, iron, lead, zinc, aluminium and so forth. Official Line versus Reality Now this brings us to the 'official line' versus reality.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

Charcoal is stable and durable. It is capable of persisting in the soil for a very long time. Of course how long may depend on the type of charcoal, conditions, soil etc. but it is no doubt capable at times of persisting for millennia. While some of the minerals in ashes may be persistent, ash is essentially a very short term fertilizer.

Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).

The biochar can also act as a habitat for many soilbased microorganisms. Microbial life has been shown to be a real necessity in gardening. Beneficial microbes help plants to take up nutrients more readily. They also help defend against plant diseases. Providing housing for the microbes is a good idea, and it improves overall soil health too!
