Spelt Spelt Spelt ("Triticum spelta"; "Triticum dicoccum"), also known as dinkel wheat or hulled wheat, is a species of wheat cultivated since approximately 5000 BC. Spelt was an important staple in parts of Europe from the Bronze Age to medieval times; it now survives as a relict crop in Central Europe and northern Spain, and has also found a new market as a 'health food'. Spelt is sometimes considered a subspecies of the closely related species common wheat ("Triticum aestivum"), in which case its botanical name is considered to be "Triticum aestivum" subsp. "spelta". It is a hexaploid wheat, which means
Crop residue annual global amount of collectable rice straw (not total produced straw) for biofuel production was estimated about 249 million tonnes, that could approximately produce 355.78 kilotonnes of hydrogen and 11.32 million tonnes of lignin by the proposed organosolv technology and it was found that China contributes to about 32% of global potential capacity to produce biohydrogen from rice straw. Nutrients in most crop residue are not immediately available for crop use. Their release (called mineralization) occurs over a period of years. The biological processes involved in soil nutrient cycles are complex. As a rough guide, cereal straw releases about 10
