Respuesta :

The statement is false. When the prairie soils are brought under cultivation, the fraction of soil organic compound carbon which disappears most quickly in not the passive fraction. Prairie soils are dark fertile soils that are formed from the accumulation organic matter produced by dense root systems of prairie grasses. Majority of these soils are found in temperature climates with variable environments.They are the most fertile soils in the world and most of the products that we use, or eat every day come from these types of soils.

Answer:

The given statement is false.

Explanation:

When the prairie soils are brought under cultivation, the fraction of soil organic compound carbon that disappears most briskly is not the passive fraction. Humus is considered as the passive fraction of soil organic matter. It is a complex and dark amalgamation of organic components, which have been modified substantially from the native form over time, and it also comprises other components that have been produced by soil organisms.  

Prairie soils are the dark fertile soils, which are produced due to the gathering of organic matter generated by dense root systems of prairie grasses. Most of these soils are witnessed in temperate regions with varying environments. They are considered as the most fertile soils found on the planet and the majority of the products used by humans comes from these kinds of soils.
