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
Cover crop recycle soil nitrogen already present. The catch crops take up surplus nitrogen remaining from fertilization of the previous crop, preventing it from being lost through leaching (Morgan et al. 1942), or gaseous denitrification or volatilization (Thorup-Kristensen et al. 2003). Catch crops are typically fast-growing annual cereal species adapted to scavenge available nitrogen efficiently from the soil (Ditsch and Alley 1991). The nitrogen tied up in catch crop biomass is released back into the soil once the catch crop is incorporated as a green manure or otherwise begins to decompose. An example of green manure use comes from Nigeria, where the
