Climate deals with the weather in some location averaged over some long period of time. Climate of a certain region depends on various factors. A change or alteration in those factors either naturally or by human means ensue a great change in climate bringing out the climate change like shifting in rain fall pattern, temperature pattern etc. Climate change  is a significant and lasting change in the statistical distribution of  weather  patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as  oceanic circulation ),  biotic  processes, variations in  solar radiation  received by Earth,  plate tectonics  and  volcanic eruptions , and human-induced alterations of the natural world...

Conservation tillage  is any method of soil cultivation that leaves the previous year's crop residue (such as corn stalks or wheat stubble) on fields before and after planting the next crop, to reduce soil erosion and runoff. To provide these conservation benefits, at least 30% of the soil surface must be covered with residue after planting the next crop. Some conservation tillage methods forego traditional tillage entirely and leave 70% residue or more. The main principle of conservation tillage includes three main points: Retention of crop residue: It helps in checking the evaporation of soil moisture by covering the soil capillary. It also prevents the soil erosion. The residue also serves as a rich source of humus and helps to increase the fertility of the soil. Soil tilling with at least 30% surface covered with residue Crop rotation: it helps to increase the soil fertility. It also eradicates the weed and pest problem.         ...

TILLAGE Tillage  is the  agricultural  preparation of the  soil  by mechanical  agitation  of various types, such as digging, stirring, and overturning. Examples of human-powered  tilling methods using  hand tools  include  shovelling ,  picking ,  mattock  work,  hoeing , and  raking . “Tillage” can also mean the land that is tilled. The word “ cultivation ” has several senses that overlap substantially with those of “tillage”. In a general context, both can refer to agriculture generally. Within agriculture, both can refer to any of the kinds of soil agitation described above. Additionally, “cultivation” or “cultivating” may refer to an even narrower sense of shallow, selective secondary tillage of  row crop  fields that kills weeds while sparing the crop plants. Tillage is a mechanical manipulation of soil to create favorable condition for the growth and development of crops. It include...
