Before being able to sow seeds and grow crops to sell, a farmer must prepare the land for the crop. This, both in reality and Farming Simulator 18, is called cultivating a field, and it is one of three mandatory steps in processing crops. In order to cultivate a field, a player will either have to begin with one of the Fields that they are given to start their farming career or make a new field for themselves. The former is easier to begin with, as creating a field involves both participating in Forestry and then eventual cultivating.
Once you have a field ready to be cultivated, a player must select the proper Equipment vehicle to do the job (or done manually). All the vehicles come with a description of what they are used for, as well as the Tools that can attach to them. This allows even the novice of farmers to learn what vehicles do what, earning them invaluable knowledge along the way. After the land has be cultivated - tilled, plowed and fertilized - it will be ready for the seed to be sown. If a field is not properly cultivated, the crops grown won't be the best they could be.
