Don't confuse this serv-, -serve with another Latin serv- which means "servant" or "slave".
The technique of strip cropping (alternating different crops) is one method of soil conservation because it is believed to provide almost total resistance to erosion.
Generally, conservatism, in politics, includes the desire to maintain, or to conserve, the existing order and conservatives usually believe that the implementation of changes should be minimal and gradual and not radical as is often the case with ultraconservatives.
Conservatives are said to value the wisdom of the past and are generally opposed to widespread reform and they are usually flexible and receptive to moderate changes, but they favor the maintenance of order on social issues, and they actively support deregulations and privatizations in economic spheres; however, ultraconservatives tend to be much more radical and extreme in their desires for maintaining certain political practices or conditions.
