At my place, peat is available as coconut peat and it is in form of dry
I have read that peat is supposed to be acidic.
But how can dry cakes be acidic?
Or is ususal peat different from cocnut peat?
How is peat made and what is the actual constituent?
Peat is usually decomposed mosses. The US Geological Survey web site
defines it thus:
"Peat is a renewable, natural, organic material of botanical origin and
commercial significance. Peatlands are situated predominately in
shallow wetland areas of the Northern Hemisphere, where large deposits
developed from the gradual decomposition of plant matter under anaerobic
(low oxygen) conditions. Peat has widespread use as a plant-growth
medium in a variety of horticultural and agricultural applications
because its fibrous structure and porosity promote a combination of
water-retention and drainage. Commercial applications include potting
soils, lawn and garden soil amendments, and turf maintenance on golf
courses. In industry, peat is used primarily as a filtration medium to
remove toxic materials from process waste streams, pathogens from sewage
effluents, and deleterious materials suspended in municipal storm-drain
water. In its dehydrated form, peat is a highly effective absorbent for
fuel and oil spills on land and water."
Since peat bogs are usually in cool temperate to sub-arctic
(near-tundra?) flat locales, India is not likely to have many. Properly
composted coconut-husk fiber can be a useful replacement for most uses.
The usual peat we use, from anaerobically decomposed Sphagnum Moss, is a
good ion-exchange medium and can soften water somewhat. It also has some
humic acids that can dissolve and make softer water more acid. It has
little effect on harder water except to color it yellowish, and may drop
the GH a little if used in a filter.
The US grows some, but most here comes from Canada.
