More on The Land
Wildlife: The damage to farm crops by wildlife should not be underestimated.  In recent years, complaints by farmers concerning crop losses that were caused by deer, geese, and other wildlife have increased significantly.  Control measures for these animals are limited, since the government protects many wildlife species.  Avoiding their favored habitat is the best way of reducing wildlife’s impact on crop production.  Farms located near woodland are going to have deer problems and resident Canadian geese will live year-round near farm ponds.
Acreage: The size of the farm has the most to do with how much land the operator has to farm.  While rented ground may be available, it is unwise to rely too much on it for your farm business because you can always lose it to someone else.  The soil type and soil conditions, such as poor drainage will affect what can be grown on the farm.  What you plan to do on the farm will affect what you need from a farm.  Grazing animals on pasture does not require the farm to have excellent soils.  Also, not all of the land on the farm may be useable for crop production, some may be in trees, wetlands, or too hilly.
