Another way to collect a stool sample is to loosely place plastic wrap across the rim of the toilet, under the seat. Then place the stool sample in a clean, sealable container before taking to the laboratory. Plastic wrap can also be used to line the diaper of an infant or toddler who is not yet using the toilet. The stool should be collected into clean, dry plastic jars with screw-cap lids.
change, and (2) climate change conditions derived from regional climate parameters projected by the. GISS general circulation model combined with a CO2 concentration of 550 ppm. The 1971 to 1995. period was simulated under neutral conditions with the purpose of defining soil conditions for 1996. It. was found that in the event of a change in climate, physical proporties would change to a lesser degree. than chemical properties. The soil bulk density would decrease by 8% with respect to the baseline sce-. nario in soils under nsk of erosion.
In addition, other factors such as location, soil fertility, crop varieties, and management practices will all affect future yields. Below we list some of the effects we could expect for agriculture due to various aspects of climate change.
