This trend coincides with similar pattern for SOC content (IISD, 2012b). Residue generated by a single crop or crop sequence has its impact on potential recyclable organic matter. 5:1. In addition, crop residue left on the ground after harvest is of concern, since it has direct impact on organic carbon recycled into soil and erosion control. , 1979). On a wider scale, aspects such as crop residue generated and left on the field has marked effect on C sequestration and emissions in the Great Plains.
Winter wheat production in large farms is common in Kansas, Oklahoma, Texas, and Colorado. The Upland cotton region in Southern Plains occurs in Texas and Oklahoma. The Texas high plain is an important cotton growing region in the plains (see Hudson, 2012). 1â•… DEVELOPMENT OF FARMS AND FARMING IN THE GREAT PLAINS: RECENT HISTORY Initiation of large-scale farming was an event of immense influence to natural vegetation of the Great Plains.

It seems crested wheat grass that was introduced into Great Plains in 1900s established rapidly and helped in reclaiming abandoned wheat fields. However, a species such as leafy spurge (Euphorbia esula) became prolific and spread like a weed. Several other grass species such as Japanese Brome (Bromus japanicus) also had its impact on perennial flora in the Great Plains (Pieper, 2002). According to Patton and Marston (1996), Central Plains were dominated by short and tall grass prairies interspersed with slush and wetlands, forests, and grassy savannahs.
