MA is Mfg Plant Code (see http://www.harriger.com/exptire.htm), L9 is a tire size code, ABCD is optional manufacturer info, 036 is mfg date (in this case third week of unspecified year ending in 6, but not 2006) The newer tires are using 4 digits, the first 2 = the week, and the last 2 = the year. For example 4202 = 42nd week of 2002.
Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.esertification often causes rural lands to become unable to support the same sized populations that previously lived there. This results in mass migrations out of rural areas and into urban areas, particularly in Africa.
A desert is a unique geographical feature found on the Earth, which covers almost 1/7th of its surface. It can be defined as an arid land with very less vegetation. The scarce amount of vegetation is seen due to less amount or lack of rainfall (annual rainfall in deserts is 25cms or even less). desert is a unique geographical feature found on the Earth, which covers almost 1/7th of its surface.
