Carbon dating practice questions

The fluxes of soil organic carbon vary in response to a host of potential environmental and anthropogenic driving factors.

Scientists worldwide are contemplating questions such as: ‘What is the average net change in soil organic carbon due to environmental conditions or management practices? These questions are far reaching, because maintaining and improving the world's soil resource is imperative to providing sufficient food and fibre to a growing population.

Since a small fraction of CO2 contains C14, some of carbon fixed within the plant is that of C14.

Animals eat the plants, ingesting the C14 which in turn enters the animal’s tissues (Warf, 212).

► This review discusses perspectives and practices to sequester more soil carbon.

►It also highlights methods and models used to estimate soil carbon pools.

Radiocarbon Every day cosmic rays bombard our atmosphere.

These cosmic rays release free neutrons which zip around our nitrogen rich atmosphere at high velocities.

As is common fact, plants photosynthesize and consume CO2, fixing its carbon.

It is estimated to be practiced over 1 billion hectares in developing countries, and to a lesser extent in the industrialized countries.

Agroforestry systems (AFSs) are believed to have a higher potential to sequester carbon (C) because of their perceived ability for greater capture and utilization of growth resources (light, nutrients, and water) than single-species crop or pasture systems.

’, ‘How can soil organic carbon sequestration be enhanced to achieve some mitigation of atmospheric carbon dioxide? Additional challenges are expected through climate change and its potential to increase food shortages.

This review highlights knowledge of the amount of carbon stored in soils globally, and the potential for carbon sequestration in soil.
