By the time the chyme has reached this tube, most nutrients and 90% of the water have been absorbed by the body. At this point some electrolytes like sodium , magnesium , and chloride are left as well as indigestible parts of ingested food (., a large part of ingested amylose , starch which has been shielded from digestion heretofore, and dietary fiber , which is largely indigestible carbohydrate in either soluble or insoluble form). As the chyme moves through the large intestine, most of the remaining water is removed, while the chyme is mixed with mucus and bacteria (known as gut flora ), and becomes feces. The ascending colon receives fecal material as a liquid. The muscles of the colon then move the watery waste material forward and slowly absorb all the excess water, causing the stools to gradually solidify as they move along into the descending colon . 
“Field Crop News” is an archive of information dedicated to the production of over million acres of field crops in Ontario and a forum for which producers, researchers and industry personnel can share information and ideas. The crop technology team with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), faculty at the University of Guelph and Ontario field crop producers continually work together to find ways to improve field crop production. The key learning and outcomes from these collaborations are captured at “Field Crop News”.
